555 timer on/off switch with momentary button

This is another quick 555 timer project I made. It takes a momentary signal from the button press and it converts it to an on signal. Press the button again and it turns it off. Definitely a useful circuit.

My First 555 timer Circuits

I recently made a few 555 timer circuits successfully. The reason I say successfully is because I have never been able to get them working in the past. All because I had the pinout all wrong. Now that I got them working, they are really cool. The first one is a bi-color LED alternating between its two colors. The second one is supposed to be a "ticking bomb" sound but it sounds more like a heartbeat. That's it on 555 timers for now but I still have a couple more ideas so stay tuned.

Bench-Puter Update

Here is a video of my bench-puter. I have added a start-up tone, knock detecting on switch, and labels. I did not take pictures, only a video.
