Today we build a LED Flasher circuit. We created blinking LED without using Arduino, by using the capacitor properties (charged and discharged) and an “and gate”. The switch distinguished between voltage differences, if there is no difference (both High) so it is Low and if one is Low and the other one is High the output is High.
The following video demonstrates how the circuit works. When the Pot is being spined it affects the blinking frequency.
