555 clock generator

its a clock generator and you can control the speed of the resistance on the  10K Ωresistor.

Cool, good job

Use battery between 5 and 15 volts. Maybe change Resistor values. Generally R2 is much bigger than R1. Try 10k and 40k or 1k and 10k for example. For the led if it blinks too fast then it will just stay on. So increase the capacitor to 47uF or greater. Led forward voltage is not 7v. Try 2.8v or 3.2v for example. Don’t need that square wave source, just use battery 6 or 9 volts.

and speed up the simulation rate.

You can even make other waveforms as well.

really?

Get rid of that square wave source, just delete it

Positive of the battery is correct, negative of battery to the ground.

Change the 40k to 1k

Change the other resistor to 10k

At the out put you can connect a resistor then a capacitor to ground.

You can play with the resistor and capacitor values to change the shape of the wave

Change simulation rate closer to 1s/s

Ok not understanding what I mean it’s ok

Delete the output capacitor for now

2.8 is realistic I have a bunch of them at home

Cool, just remember 555 timer limit is 1MHz
