Time delay circuit to reverse the rotation of DC motor when input is high
I am trying to design a circuit to use to control a DC motor according to the output of a capacitive proximity detector.
The circuit should turn ON the DC motor in forward direction when the hand ...

How to create a clearance area around a single PAD in Altium
I'm creating large circular pads (13.5 mm diameter) for some capacitive buttons on ALTIUM.
I want to create a circular clearance non-copper space area around each of these pads (around 1..2 mm) to ...

Increase measurement distance of a capacitive proximity sensor - Arduino project
I am working on a 3D tracking interface project that I found online here.
However, instead of using my hand to track, I want to track an aluminum ball with a 2 cm radius, which is connected to ground....

Touchscreen Sniper [closed]
I was reading today about how capacitive touch works. This article on the Arduino site mentions that with a 40 Megaohm resistor you could detect an untouched "touch" from possibly 24 inches away.
My ...

Choice of sensor for detecting touch (on/off)
I would like to detect a user's touch on a shop window (at a specific area, there would be a 'call to action' marking on the window, i.e. 'touch here')
Any sensor to detect this must be contained ...

Can I use a capacitive sensor to detect a person proximity without touch?
I only see uses of capacitive sensor to detect touch. But I wonder if I can calibrate a capacitive sensor to detect if a person is close enough, even if the person is not touching it.
I intend to use ...
