Arduino Projects
A temperature sensor with 8 segments display with an Arduino Uno microprocessor. There are other small projects including Stepper motors, photoresistors, relays, RFID modules and more.
ESP32
Using an ESP32 microprocessor and a servo motor, I made a automatic voice activated garage door controller. This required a copper trace PCB soldering of the microprocessors with some server side scripting. This required you to use the home automation application on IOS devices.
