Project Touch Delay

Enjoy!

This project is a very simple idea where after you touch a sensor and LED slowly turns on or off, hence the delay. The delay is caused from the charging or discharging of a capacitor. This circuit here is the delay but with a button instead of a touch sensor: And this circuit is the actual touch part, where a simply wire acts as the ‘touch sensor’:

Basically, since we as humans carry a charge, when I touch the wire it causes the transistor to open its gate, allowing a capacitor to discharge.

At the end I wrote that it need to be the wall power, however this isn’t actually true.

I ended up using a slightly modified version of this in one of my future projects. I just put this here so I can reference it later.
