From the project
Collection of electronic circuits I designed, tested, and documented using KiCad
A beginner-friendly photodiode alarm project that demonstrates how light from a flame can activate a transistor-driven LED and buzzer output.
This project demonstrates an educational optical fire-alarm concept using a photodiode, BC547 transistor, LED, and buzzer. Light from a flame reaches the photodiode, the photodiode changes the sensing condition, the transistor stage responds, and the LED/buzzer output path activates.
