In this tutorial, I’ll first blink “an LED” using the positive pulse generated by a “DIY 555 Pulse Generator Module” , followed by “two LEDs” alternating and flashing at a regular interval.

For this tutorial we need:

2 x LEDs
1 x 555 Timer IC
1 x 10µF Capacitor
1 x 220Ω Resistor
1 x 1kΩ Resistor
1 x 10kΩ Resistor and/or
1 x 10kΩ Potentiometer”
