M5Stack Node for The Things Network
https://blog.hackster.io/m5stack-node-for-the-things-network-617200895826
M5stack.The system is based around 5×5×1.2 cm stackable modules, with the core module built around a ESP32, making it programmable both from the Arduino development environment and MicroPython.
Since its Kickstarter days, The Things Network has grown into a global crowdsourced data network for the Internet of Things, and arguably has become one of the main driving forces in making LoRaWAN the leader in the war for low-powered, long-range, but low-bandwidth wireless connectivity.
Despite this, it’s only recently that LoRaWAN hardware has started to become cheaper and more accessible.

Use This DIY RESTful Smart Power Plug However You Want
https://blog.hackster.io/use-this-diy-restful-smart-power-plug-however-you-want-be47d17b9365
Smart power plugs are probably the first home automation devices people buy when they get started with IoT. It’s convenient to just ask your home voice assistant to turn off a light instead of having to walk all the way over to the switch on the wall. But, virtually all of the smart plugs on the market use proprietary communication protocols. If that doesn’t appeal to you, there is an alternative: this RESTful DIY smart plug

The Internet of… Power Outlets?
https://blog.hackster.io/the-internet-of-power-outlets-ac8fcacde48d
This system is designed to distinguish between benign power surges when an appliance starts up and actual dangerous situations. It currently runs on a Raspberry Pi 3, using a USB sound card and current clamp for data acquisition and processing.
MIT engineers build smart power outlet
https://news.mit.edu/2018/mit-engineers-build-smart-power-outlet-0615
Design can “learn” to identify plugged-in appliances, distinguish dangerous electrical spikes from benign ones.
The problem with today’s arc-fault detectors, according to a team of MIT engineers, is that they often err on the side of being overly sensitive, shutting off an outlet’s power in response to electrical signals that are actually harmless.
In this case, the team’s machine-learning algorithm is programmed to determine whether a signal is harmful or not by comparing a captured signal to others that the researchers previously used to train the system.

Build a 3D Room-Mapping Robot with Unity 3D and $25
https://blog.hackster.io/build-a-3d-room-mapping-robot-with-unity-3d-and-25-882c6fdbd008
This 3D room-mapping robot from Matthewh8 is a fantastic example of just how much you can do on a limited budget today.
This robot keeps control costs down by using an ESP8266 NodeMCU, and has been paired with an L298N dual H-bridge motor driver to provide movement.
integrating the versatile Unity 3D app. That gives the robot the ability to track any arbitrary object, and even to map rooms in 3D.
ROOM MAPPING ARDUINO ROBOT WITH UNITY 3D
http://www.instructables.com/id/ROOM-MAPPING-Arduino-Robot-With-Unity-3D/
This project uses an Arduino robot running a ESP-8266 Node MCU that communicates (and drives around) with a mobile phone. The phone is running an app made in the video game engine Unity 3D that does 3 things:
1.) The first scene allows you to drive around the robot with a camera feed going back to your computer. You can use the arrow keys to drive it around in any direction and the video feed allows you to keep driving even when the robot is out of sight.
2.) The second scene allows the robot to track anything you put in front of it. You can click the screen to initialize the tracker and then the robot will follow around that object.
3.) The third scene allows you to drive the robot with your computer using the arrow keys. The app uses an augmented reality SDK to find the walls and ceiling which it sends back to your laptop giving you a digital representation of your environment.

ABOUT THIS PROJECT
We all know that being without that special person in your life can be difficult, but what if you could send love and affection remotely over the Internet by just hugging a pillow?
Now, we can’t really send hugs… but what we can send is a sweet emoji through a messaging app, triggered by you giving a pillow a hug.
When you hug the I Love You Pillow you will hear the sound of a heartbeat coming from the buzzer inside. Depending on the length of your hug, a different emoji will be sent from a Telegram Bot to whatever chat you choose.

ABOUT THIS PROJECT
Smart Plant IoT Demo
Introduction
Gardening might be a fun hobby for some, but for many others it’s much of a hassle to deal with. In this article I am writing a simple guide on how to build a smart IoT plant that would send sensor data to Azure IoT Hub and storing over Azure SQL via Azure functions, at the same time both auto and remotely control water for the plant.
Helium IoT Hub connects to Azure IoT Hub in a seamless fashion, in this article we will explain how the entire process works. Since the entire project is serverless, the only code needed for the entire process to work is just Azure Function and Arduino code.

Flipping a Light Switch with Servos Instead of a Relay
https://blog.hackster.io/flipping-a-light-switch-with-servos-instead-of-a-relay-dd7beb68fe77
Both The Clapper and IoT switches operate with the use of relays, but that doesn’t mean there aren’t other ways to tackle the problem — like this build from Robin Hartley that physically flips a light switch.
The servos are controlled with an Arduino Pro Micro, and a LM393 sound sensor lets the user toggle the light by snapping or clapping.

Distributed Datalogging Network
https://www.hackster.io/scijoy/distributed-datalogging-network-c88169
Log data remotely from a fleet of ESP32s and graph the data with Google services
Helium made it easier to register devices and send data to cloud platforms like Azure, Amazon Web Services, and Google Cloud Platform. Our system allows the user to plug in a sensor and record data with only a few configuration variables.
A system like this could be used in classrooms to compare results from small group experiments or at home for IoT data recording. A more robust version could be used in industrial applications to monitor machines or processes.

https://blog.hackster.io/this-nfc-auto-door-lock-works-with-existing-heavy-deadbolts-5973011b180f
Locking and unlocking doors is one of the most popular uses of NFC (near-field communication), and you’ve probably used it yourself at an office. The most common way to lock a door with NFC is with a magnetic bolt that’s powered through a relay. They can either be normally-open or normally-closed, depending on whether safety or security is more important in the event of a power failure.

Blinds (Or Any High Power Motor) Control
https://www.hackster.io/gomecin/blinds-or-any-high-power-motor-control-27f633
How to control several blinds with inexpensive relay boards (not ruining them) with physical buttons and remotely simultaneously.
wanted to automate everything, starting with the blinds. What seemed to be an easy project turned out to be a bit of a nightmare: the relative high power motors (150W) were destroying my relays and triacs, what wireless communication and controller to use and how to make it work was not obvious, noise in the lines were causing random activation of the blinds (pretty scary in the middle of the night)…
When controlling motors, an important issue is their inductance, which causes that when trying to open the circuit, the current insists on keeping flowing through your breaking device, causing a very high voltage. If you try to break the circuit with no precautions with a small relay, their contacts will stick together, and if you use a triac (solid state relay) the over-voltage (in my case I measured peaks of more than 1600V) will destroy the semiconductor.
I realized by googling, that other people had issues with this, but they took the easy, expensive and voluminous way, they just get bigger relays, still needing the cheap relays just to activate the bigger ones, while the contacts will still suffer and may fail eventually. As an engineer I could not allow myself not to get the most efficient solution.
In the schematic below you have the solution to spare this big relays just by adding one resistor, one capacitor and one varistor.
The varistor protects the triac from an over-voltage. The resistor plus capacitor forms a RC Snubber circuit that absorbs the energy during the breaking commutation.
