Above you can see one of the example circuits provided to help ... or timing data like in the 555 timer circuit above. Where does this fantastic tool come from? [Humberto Evans] and [Mike Robbins ...

The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the most widely used ICs due to its reliability and flexibility.

With a little work, you could probably adapt this idea to any number of circuits out of the 555 playbook, like a PWM generator, for example. There’s almost nothing a 555 can’t do. If you want ...
