The pinout at 3:31 is wrong, pins 6 and 8 should be swapped. Sorry for that!

This video shows how to build a basic NE555 timer IC chip circuit in astable configuration. The example shows how to blink an LED ~ once per second. By the end you will undestand how it works and learn about the multiple use cases of the 555 timer. You will also learn how to change the timing of the pulses.
