This project is on how to make a simple flashing/blinking LED circuit using transistors on a breadboard. watch the video for detailed step by step instructions on how to build this circuit. Changing the flashing rate is also possible by changing the value of capacitor used, which is shown later in the video.
Components Needed:
- 1 npn transistor (BC547)
- 1 pnp transistor (BC557)
- Resistors: 22R, 1K, 1M
- Capacitor: 2.2uF
- Breadboard
- Few Breadboard Connectors
- Power Supply: (3-6)V
