The heart of the device that [Kerry] designed is based on 6 power MOSFETs, a few operational amplifiers and an Arduino compatible ATmega328p microcontroller. Sense resistors are used to measure ...

His Mario themed Christmas Ornament uses a Silicon Labs FM972 micro controller, capacitive sensing, PWM controlled 8 bit audio, and blinky lights. The interesting part is some of the construction ...

Unlike SBCs, microcontrollers ... a capacitive moisture sensor. Again, you’ll need to interface the sensor with your ESP32 ...

Using the Arduino microcontroller, we will explore some of the essential and useful electronic sensors (light, sound, motion, sonar, infrared, angle bending), powerful actuators (relays, motors, ...
