- Set the pin to HIGH (5V), this will turn the LED on.
- Wait for 1000 milliseconds, or one second.
- Set the pin to LOW (0V), cutting the power to the LED and turning it off.
- Wait for another second, and then repeat everything again.

The circuit for blinking an LED using transistors is called an Astable Multivibrator. … The two capacitors C1 and C2 will alternate between being charged and discharged and thereby turning the transistors ON and OFF. When a transistor is ON it allows current to flow through it so that the LED above it will light up.
