How it works

A very simple circuit that you can build to blink or flash LEDs. The circuit is built using transistors, resistors, capacitors, and LEDs. Of course, you will need a breadboard, wire jumpers, and a power source. The parts list includes:

NPN Transistor, 100hFE, Qty: 3

Resistor, value 470 Ohms, qty: 6

One terminal Vs, 9V Qty: 3

Capacitor, 470 uF, Qty: 3

LED, Qty: 3

Breadboard

Jumper wires
