Touch Volume Control Circuit
This touch volume control circuit has two touch pads which enable the user to increase or decrease the volume of an audio amplifier simply by touching the relevant touch pads. The advantages of this solid-state volume control are: very long life due to the absence of any wear and tear, quick and easy finger touch […]
7 Best Touch Sensor Switch Circuits Explored
In this post I have explained 8 easy methods of building touch sensor switch circuits at home, which can be used for switching 220 V appliances ON/OFF with mere finger touch operat ions. The first one is a simple touch sensor switch using a single IC 4017, the second one employs a Schmidt trigger IC, […]
How to Use TTP223 Capacitive Touch Switch Module [Pinouts Explained]
In this article I have explained how to connect and use the TTP223 capacitive touch switch module. These modules work using 2.5V to 5V. They are all pre-debounced, all you need is to provide the DC supply across the VC and GND terminals, and you get an output in the middle. So it is really […]
Simple Touch Operated Potentiometer Circuit
In this touch operated potentiometer circuit we have two touch pads, which produce a slowly increasing voltage at the output when one touch pad is touched, and a decreasing voltage when the other touch pad is touched. When the touch contact is removed the voltage holds at that particular increased or decreased level “permanently”. Touch […]
Make this Touch free Faucet Circuit for Hands-free Tap Control
A very simple touch free faucet circuit or touch free automatic tap circuit can be built using as little as an IC 555 and a few passive components, in order to implement a contact less water supply operation from the attached facet or the tap. Drinking Water is Precious Pure drinking water which we normally […]
