I use only resistors with a library of a capacitive touch sensing for the usage of a controller in PC. I use Arduino Micro for this though and search for KappaPad in google. I dont know why the serial plotter works this way tho. I get the basics for the sensing but for my project, i did six sensors on 1 controller and the code for PC connection is still bugging me. Huhuhuuu

You can use your body as a ground sink for an oscillating electric charge on the lamp.
Once you touch it, your body will sink the energy and an capacitor should start discharging - a logic inverter can then turn a tflipflop on and off which can turn a relay on and off. You don't need no buggy arduino for this project.

The problem was the capacitance of the lamp and the fact that the electromagnetic field from the mains wires kept it charging slowly. And also fixing things the hardware way is not the best option in most solution. In this case you should have fixed it the software way by increasing the discharge thereshold. Should work.

I don't want to diminish your enthusiasm, but I've seen highly effective NE555 demos that do exactly the same thing as your solution. am I missing something here? My gut says this is a sledgehammer for a finishing nail, but maybe I'm overlooking something important. Totally willing to admit I'm wrong. but still.

This is a bit random but, I have a cooker which turns on for 5 minutes using a touch sensitive switch. In order to keep using the cooker you have to constantly touch the switch midway through cooking or otherwise it turns off. Any tricks I can use to get around this?

All you need to do is, differentiate manual touch from noise of lamp. A human touch is definitely longer than the noise. Start a counter whenever touch is triggered and stop when its released. Based on the count value you can decide whether it's touch or noise.

Great explanation. i found the effect a while back but glad the ESP makes using it without extra circuitry possible. still finicky tho. The noise was most likely from mains voltage itself. Ive also had issues being too close to a wifi source.

Well i think that the whole metal body of the lamp acts like an antenna. Try to isolate the base from the lamp holder and connect the system to the base you ll have less noise and that might work

very nice video, There's a another capacitive touch sensing called projected capacitive sensing or mutual capacitance. I couldn't find much on YouTube, Maybe it could be subject for another video?
