Sink every shot with this robotic backboard
https://blog.arduino.cc/2020/05/12/sink-every-shot-with-this-robotic-backboard/
The setup uses a Microsoft Kinect, along with a Windows-based computer to calculate the inbound ball’s trajectory. On approach it passes data to an Arduino, which then moves the hoop into position via three large steppers and a linkage system.

How to Send Multiple Sensors Data wirelessly using Arduino & 433Mhz RF Rx Tx
https://www.electroniclinic.com/how-to-send-multiple-sensors-data-wirelessly-using-arduino-433mhz-rf-rx-tx/
How to Send Multiple Sensors Data wirelessly using Arduino & 433Mhz RF Rx Tx- In this project you will learn how to connect multiple sensors with Arduino and send Sensors data wirelessly using 433Mhz Radio Frequency Rx and Tx modules. Rx Tx stands for Receiver and transmitter. In this project we will connect 6 Flex Sensors with the Arduino and send their values wirelessly. This project can be easily modified, different types of multiple sensors can be interfaced with the Arduino Uno, Arduino Mega, or Arduino Nano, etc, this way advanced level projects can be designed. As this project is based on the 433Mhz short range radio frequency communication, so this can be ideal for control a robot with multiple functions, Home or office automation, etc.

Arduino Mains Monitor with SIM900A GSM messaging.
https://andydoz.blogspot.com/2015/10/arduino-mains-monitor-with-sim900a-gsm.html
So, we have a plan. Measure the mains voltage (and why not frequency at the same time?), and act conditionally on it’s failure. We also need to get it to send us a message. We’re going to need some form of uninterruptable power supply, so when the mains does go off, our micro will still be running, and we’ve got power enough to send the message. Here’s the circuit

Hospital radio streaming codec and monitor.
https://andydoz.blogspot.com/2020/03/hospital-radio-streaming-codec-and.html
Things have been getting a bit, well, unreliable at the hospital radio studio of late. We’ve been plagued with power outages, and things don’t recover well.
Here’s what I’ve got in mind.
Two Raspberry Pi’s, one transmitting, one receiving. The receiver will be monitored to ensure that the stream is up.
The Pi’s audio will be fed into and internet-equipped Arduino of some description, which will do the monitoring for us.

AN ARDUINO AS A PLL
https://hackaday.com/2020/05/23/an-arduino-as-a-pll/
At the heart of many amateur radio and other projects lies the VFO, or Variable Frequency Oscillator. Decades ago this would have been a free-running LC tuned circuit, then as technology advanced it was replaced by a digital phase-locked-loop frequency synthesiser and most recently a DDS, or Direct Digital Synthesis chip in which the waveform is produced directly by a DAC. The phase-locked loop (PLL) remains a popular choice due to ICs such as the Si5351 but is rarely constructed from individual chips as it once might have been. [fvfilippetti] has revisited this classic circuit by replacing some of its complexity with an Arduino

Arduino Hot Plate – What’s for dinner?
Posted by wolfgangfriedrich in Wolfgang Friedrich’s Blog on May 7, 2020 5:05:49 AM
https://www.element14.com/community/people/wolfgangfriedrich/blog/2020/05/07/arduino-hot-plate
“I am going to build a hot plate for reflow soldering with a CMH heater element. The GPIO is controlling power through a PWM controlled power FET and the ADC is reading back the temperature of the hot plate through an thermistor (maybe more sensors if needed). With some calibration I can program a nice temperature profile for reflowing boards.”
And to my surprise, I received an Arduino Nano Every in the mail and got to work.

Arduino Based Mini Robot Arm
http://ardulink.blogspot.com/2020/05/arduino-based-mini-robot-arm.html
This simple project explains how to build an Arduino based robot arm.
The objective is to control each part of the robot arm separately using servo motors and potentiometers.
In this project, 3 potentiometers are used to control 3 servo motors to form up a mini robot arm.

This LED lamp uses the tensegrity principle, not magnets, to create its levitation effect.
Levitating LED Lamp
https://www.instructables.com/id/Levitating-LED-Lamp/
Have you ever played around with magnets and tried to make them levitate? I’m sure many of us have, and although it might seem possible, if placed very carefully, after a while you’ll realize it is actually impossible to do. This is because of Earnshaw’s Theorem, which proves that it is impossible to levitate an object with only ferromagnetic materials. However, we have a workaround. Instead of using magnets, we will levitate the lamp using an illusion called tensegrity, making a lamp that looks like it is floating!
