This is a very simple touch sensor switch that is build with the 555 timer IC. You just need to touch the metal plate and the relay gets energised and is kept in this state for about 100 seconds, then ...

Fig 3. Circuit diagram. In this circuit diagram, we’ve employed three sensors and three relays to control three separate appliances. If you wish to extend the control to more appliances, you have the ...

To integrate a capacitive touch sensor into a circuit, you need a microcontroller that can generate and measure the voltage signals for the capacitor. There are many microcontrollers that have ...

The circuit is very simple, I have used the GPIO pins D23, D22, D21 & D19 to control the 4 relays. The GPIO pins D13, D12, D14 & D27 are connected to the TTP223 touch sensor to control the 4 relays ...

Usage Connect the Arduino to your computer via USB cable. Place the circuit on the breadboard, carefully following the wiring in the circuit diagram. Attach one end of a conductive wire to the leaf of ...

The purpose of this paper consists in development of hardware, ensuring artificial tactile sensing of an anthropomorphic robot. Through analysis, performed to that end, it was discovered, that the ...
