Pin 3 is connected with resistor R2 and Pin 8 is connected with 6V power supply. Pin 5 of 555 timer IC is connected with a capacitor of 0.01 μf. We can use two pieces of a conductor to make the touch plate, connected with the trigger pin of 555 Timer IC and ground respectively. Here, 555 Timer IC is configured in Monostable mode. Touch-Plate (conductive material/Metal)Ĭircuit Diagram for Touch Switch using 555 Timer.Gather the following components before starting the design process of the circuit. Related Project: PCB Design of LED Flasher Circuit using 555 Timer.Go through the below table to understand the different pins and function of 555 Timer IC. This 8 pin IC is one of the most commonly used IC in electronic components. This IC is one of the most popular and widely used for providing time delay, as an oscillator or as a flip-flop element. The 555 Timer IC generally operates in three different modes depending upon configuration namely A-Stable, Mono-Stable and Bi-Stable modes. Before getting started with the design process of this project, let’s give you a quick overview of the 555 Timer IC. Here, the touch plate triggers the output of the 555 Timer IC, whenever sense a touch. To design this highly durable Touch sensitive switch circuit, we are using a 555 Timer IC as the main component. Touch-Sensitive Switch Circuit Using 555 Timer IC
#Touch timer switch how to
There are a number of ways to design the circuit by using different microcontrollers, ICs or even with some transistors. Touch sensitive switch circuit gives a sleeker view to the devices like UPSs, Mixer-grinder.These switch doesn’t need direct contact with metal and therefore completely eliminated the security risks.Touch switches have an infinite life and thus reduces the cost of maintenance.In addition, it is more superior to mechanical switches due to various factor that includes: The best part of this circuit is that very few components are required for the construction. This circuit turns ON and OFF an LED whenever it senses a touch. In simple words, it is a kind of circuit which can be operated or toggled just by a touch. In this article, we will be discussing the simple touch sensitive devices which can be used to operate LED or any home appliances. If you are the one looking for such a smart device then here is your halt. As a human being, we definitely need certain actions to be done with a touch instead of pressing buttons. Machines have been eliminating humans on job tasks for several centuries.
