Alexa BBQ/Kitchen Thermometer with IoT Arduino and ePaper
https://www.hackster.io/rogertheriault/alexa-bbq-kitchen-thermometer-with-iot-arduino-and-epaper-63c64f
“Alexa, ask my thermometer to make Yogurt.” No fiddling with thermometer settings, Alexa can do it for you.
I created this next iteration to take advantage of multiple Alexa devices we have throughout our home, new capabilities available via Alexa Skills Kit and AWS IoT, Lambda, DynamoDB, and more-capable Arduino software and hardware.
We now have flexible ways for Alexa to help us monitor and control what’s cooking in the kitchen, outside in our smoker/grill, and from any room and device in the house.

Here’s how to make Alexa control a toilet because why not
https://techcrunch.com/2018/02/21/heres-how-to-make-alexa-control-a-toilet-because-why-not/?utm_source=tcfbpage&sr_share=facebook
Alexa-controlled toilets are a thing in 2018 but cost thousands. An enterprising person can make their own by following these instructions. It takes a bit of work, multiple components and about $750 (plus the cost of the toilet) but the end result is a voice controlled toilet and everyone needs that in their life.

ESP-01 Bridges the Gap Between IR and WiFi
https://hackaday.com/2018/02/20/esp-01-bridges-the-gap-between-ir-and-wifi/
[Emilio Ficara] dropped us a line recently about his efforts to drag his television and receiver kicking and screaming into the modern era. His TV is old enough that it needs an external tuner, which means it requires two separate remotes to properly channel surf. He wanted to simplify the situation, and figured that while he was at it he might as well make the whole thing controllable over WiFi.
To begin the project, [Emilio] had to capture the IR signals from the two remotes he wanted to emulate. He put together a quick little IR receiver out of parts he had in the junk bin which would connect up to his computer’s microphone port. He then used an open source IR protocol analyzer to capture the codes and decode them into hex values.

Let an Arduino notify you when the coffee is ready
https://blog.arduino.cc/2018/02/23/let-an-arduino-notify-you-when-the-coffee-is-ready/
His device uses a current sensor to monitor power usage of the coffee pot, and after some observation, he was able to pick out its brewing pattern—7A at 10 minutes, then quick cycling to keep the pot warm.
The system features an Arduino Yún for brew tracking and sends an alert via his office communication tool to let everyone know that a fresh pot is ready. As with many projects, the first iteration started life on a breadboard, but now exists on a manufactured PCB as a shield.

Sentinel Security
https://www.hackster.io/user16807/sentinel-security-735c54
Sentinel Security is a smart home monitoring system that uses an Amazon Alexa skill and Arduinos with PIR motion sensors to protect a home.
Amazon Alexa and Arduino have been forces to be reckoned with in their respective industries. With the prospects and realization of smart homes coming to fruition, the combination of these two companies in one project creates an exciting dynamic for innovation. One area that can be improved with these technologies is home security.
The Alexa skill acts as the mediator between you and your Sentinel security system. It can arm, disarm, and recount the disturbances stored in the Firebase.
The sensors consist of an Arduino Nano R3, PIR motion sensor, NRF24L01 radio module, and four AA batteries in a holder. Multiple sensors can be named and used in different locations, both indoor and outdoor to create a network of sensing capabilities for a smart home.
The Raspberry Pi base station compiles the sensor outputs when disturbances occurs and uploads them to the Firebase database from which the Alexa skill can retrieve information.

Alexa Enabled USB Power Switch
https://www.hackster.io/TinamousSteve/alexa-enabled-usb-power-switch-93bab3
Many devices are powered by USB power now, but few home automation systems provide USB power switching. “Alexa, turn off the ThingyStick!”
This project allows you to control the power supply to USB powered devices via the internet, and by using the Tinamous SmartHome Skill for Alexa, you can enable voice control for your dumb USB devices.
Currently their are very few devices on the market to control USB power remotely
Simple power control: Internet enabled power switching, either via Alexa voice control or other commands through Tinamous. On and Off.
Smart power control: Many USB lamps have touch controls to switch the lamp on, which means we can’t switch the light on remotely, but we can switch it off, and a lot of the time that’s all we want
With smart power enabled, the off command will turn the lamp power off for a few seconds before restoring power to the device. Enough to turn the lamp off, but also allowing normal operation after.
Power monitoring: If you’re developing USB powered hardware you may well want to know how much current you device is taking, particularly when it is first switches on, or you may like to profile battery pack charging. With the on-board INA219 you can monitor current consumption
Power failure: By using the battery option on the MKR 1000 we can monitor the USB supply voltage and send notifications if the input power has failed.
This project is fairly simple, an Arduino MKR1000 at the heart, USB power switching using two LM3526M’s to provides high side switching and fault detection (low voltage, over current), along with power monitoring (voltage and current) using an INA219, and finally LEDs and switches for local control options.

Alexa Enabled Thermostat for Junkers Gas Heater

Tomi Engdahl says:
Even a couple of years ago, no one thought wifi would be suitable for IoT devices. After that, however, companies have offered wifi solutions with less and less power. Silicon Labs’ first wifi circuit cuts power consumption, praises Riku Mettälä, the company’s wifi product.
- We decided to develop our own wifi chipset two years ago to make our IoT radio range comprehensive. The now announced WF2200 modules are the result of this work, Mettälä told Nürnberg.
Wifi circuits are needed in many of the IoT applications that need a higher data rate. – For example, surveillance cameras should get a picture at 5-8 megabits. This is not possible with Bluetooth, Mettälä emphasizes.
However, these devices still need to be powered by battery / battery power, so power consumption should be kept as low as possible. According to the article, the current consumption of circuits and modules is 138 milliamps. This is up to 40-50 percent less than the wifi of competitors. At reception, SiLabs circuitry consumes 48 milliamps, which is also the lowest in the market.

Tired of your ordinary Junkers/Bosch room thermostat? Or is it giving hiccups like mine? Time for an upgrade!
Thanks to an ESP8266 and Amazon Alexa, the central heating can now be controlled from anywhere, and even by voice!
Some modern gas boilers have adopted an open standard (OpenTherm) for the interface between the gas boiler and the room control unit, but in my installation, the interface is proprietary by the manufacturer. The solution shown here replaces a Junkers (Bosch) TW2 room control unit, or any compatible unit.

Air Surfer
https://www.hackster.io/antonramenskiy/air-surfer-a2d80f
It is a device that measures CO2 level, inside and outside temperatures and humidity.
The most expensive part of the project was mh-z19 CO2 sensor. It is relatively cheap among other CO2 sensors while providing reliable measurements and auto calibration function.
Auto calibration is simple. When I leave my apartment there is no one who consumes oxygen, so CO2 level drops to the outside level, which is 400ppm. If readings are somewhere below this figures sensor calibrates.
It can communicate via UART and PWM.
Then I used SI7021 temperature and humidity sensor for indoor monitoring that uses I2C protocol and connects to SDA and SCL pins. Not expensive, industrial high precision.
For outside temperatures I used ds18b20 enclosed in a stainless steel capsule. Cheap and accurate readings.
For the time I purchased DS 1307 RTC module that used I2C.

Monitor Power Consumption of Low-Power Devices
https://hackaday.com/2018/02/28/monitor-power-consumption-of-low-power-devices/
Perhaps the most important consideration to make when designing a battery-operated device of any kind is the power consumption. Keeping it running for longer between battery changes is often a key design point. To that end, if you need to know how small programming changes will impact the power consumption of your device then [Daniel] has a great tool that you might find helpful: an ESP8266-based live power meter.

ABOUT THIS PROJECT
Hello all,
In this project I will introduce to you a pan-tilt controlled by cell phone.
All movements of the cell phone are reproduced in the pan-tilt device via Bluetooth.
The assembly is very simple using an Arduino R3 (or similar) and two shields over it.
I started this project thinking about a device to support newbies in home astronomy giving them an easy way to indicate the right position for the telescope to find out in the sky any planet, star or constellation.
You just need use this device as a sky pointer together with apps like Sky Map.
Very easy and fun!
Video
1 – Material list
All you need is on the following list:
Arduino Uno R3 (or similar)
1Sheeld – Android version (shield for connection to cell phone – Android)
Motor Driver Shield (for servo motors)
02 x Micro Servo Motors SG90 (or similar)
Pan-Tilt SG90 kit
Power supply (9V x 1A) with plug P4
USB cable (connection between Arduino and your Computer)
2 – Assembly
The assembly is very simple with no soldering and few wirings.
Follow the next steps:
Put 1Sheeld board over the Arduino board.
Put the Motor Driver Shield over the 1Sheeld board.
Connect the cable of Tilt axis in the Motor Shield plug (Servo 1).
Connect the cable of Pan axis in the Motor Shield plug (Servo 2).
3 – 1Sheeld
According with their developers, “1Sheeld turns your smartphone into 40 different Arduino shields”.
This shield is very interesting because you can connect an Arduino board via Bluetooth to a cellular phone and use all its available sensors.
The connection is simple and you have all necessary libraries available for Arduino.
With the library of Orientation of 1Sheeld, the Arduino program will read the axis X and Y of your cell phone and translate them to the angular position of each servo motor.
One important detail is each cell phone can have a different origin/reference for the axles X, Y, Z.
Examples for future developments:
• With the app Sky Map it will be possible to automatize the positioning of a home telescope.
• It can be converted on a personal “follow me camera” to capture images or videos as personal camera-man.

Use IFTTT to Turn an ESP8266 into a Wi-Fi Button à la Amazon Dash Button
https://blog.hackster.io/use-ifttt-to-turn-an-esp8266-into-a-wifi-button-à-la-amazon-dash-button-5a167ba11f00
Amazon’s Dash Button was originally created to give you an easy way to order a specific product at the touch of a physical button. It works by connecting to your home’s wireless network, and fires off a request to Amazon when the button is pushed. They’re inexpensive (for promotional reasons) and hackable, so they gained popularity with hackers and makers for other non-shopping tasks.
If you don’t have an Amazon Dash Button, however, you can follow this guide to build own with an ESP8266 that has far more potential. The core functionality is provided by the IFTTT service, which is free to use. IFTTT uses a straightforward trigger-event logic, and works with a variety of services for both the triggers and events.

https://blog.hackster.io/use-ifttt-to-turn-an-esp8266-into-a-wifi-button-à-la-amazon-dash-button-5a167ba11f00
In this case, the trigger is a button press on the ESP8266. IFTTT provides a webhook that works on any ESP8266 that’s setup to be programmed with the Arduino IDE. All you have to do is use the ESP8266WiFi library to get it online, and then have it make the IFTTT request (using your unique API key) whenever the button is pressed. Then just add a LiPo battery and voltage regulator to make it wireless.
