Because students are using it, it needs to be short-circuit-proof – no possibility that a mix-up in control signals can cause the drive to short out the rails (see DANGER, right). BTW, don’t use these ...

Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow fo… ...

Arduino Uno. 4-channel relay module. PIR motion sensor. Steps: Use Arduino to handle sensor input and relay control. Pi runs a Python Flask server with a simple UI to toggle GPIO pins via serial ...
