I am building a 4-channel touchless switchboard. Arduino Uno, as the heart of the project, surrounded by four ultrasonic sound sensors, offers a simple, low-cost, and novel solution. The switches can ...
The objective was to find a way to turn a light on and off using the SparkFun RedBoard and interacting with the Arduino software using a Python script. We set out to have a user input a “1” or “0” ...
