Electronics and Circuits Module Guide
Follow Voltage Vera as a small board must power its lamp, switch, and sensor safely under real changes.
This board powers a lamp, switch, and sensor.
Trace power from the source to each load.
Check what each part can safely bear.
Test loose wires, heat, and a weak supply.
