From the project
Collection of electronic circuits I designed, tested, and documented using KiCad
A beginner-friendly touch-controlled switching project using a touch sensor input, a BC547 transistor stage, and a low-power output indicator.
This project demonstrates a touch-controlled output circuit. The KiCad schematic labels U1 as touch sensor, Q1 as BC547, J1 as input, and LA1 as Lamp. In the verified prototype, the touch sensor module was a TTP223 capacitive touch sensor module, and the output indicator was a miniature incandescent flashlight bulb.
