ray @ rayshobby.net build a wifi enabled color led matrix using ESP8266. He writes: Last Thursday I had a lot of fun doing a workshop at my college (UMass Amherst) where I taught students to use a WiFi-enabled Color LED matrix combined with Javascript programs to create animations displayed onto the LED matrix. The matrix […]
4-20 mA current output for Arduino Uno
https://www.electronics-lab.com/4-20-ma-current-output-arduino-uno/
Giovanni Carrera writes: The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller ATmega328 and numerous other chips, such as the PIC. One of the more interesting applications of this circuit would be to replace or to realize a smart sensor with Arduino.” 4-20 mA […]

ADXL354 – MEMS ICs detect structural defects
https://www.electronics-lab.com/adxl354-mems-ics-detect-structural-defects/
Three-axis MEMS accelerometers, Analog Devices’ ADXL354 and ADXL355 perform high-resolution vibration measurement to enable the early detection of structural defects via wireless sensor networks. The low power consumption of the devices lengthens battery life and reduces the time between battery changes. by Susan Nordyk @ edn.com The analog-output ADXL354 and digital-output ADXL355 offer selectable measurement […]
€15 IoT Geiger Counter using ESP8266
https://www.electronics-lab.com/e15-iot-geiger-counter-using-esp8266/
Geiger counters are devices used to detect radioactive emissions, most commonly beta particles and gamma rays. The counter consists of a tube filled with an inert gas that becomes conductive of electricity when it is impacted by a high-energy particle. The Geiger–Müller tube or G–M tube is the sensing element of the Geiger counter instrument […]
