How to make a Touch sensitive light Circuit Diagram Touch Lamp Control Dimmer. HHere'sanother simple project where you use a touch sensor to control the brightness of your lamp, not just turn the light on/off. Also, we'll use an Arduino to design this circuit. Take a look at the circuit diagram below: Components Needed. Here are the components you need for this circuit: Breadboard (1) Touch Figure 1. Phase control waveform for an AC mains voltage dimmer. Image source: LEDnique.com. Your LED circuit is low voltage, requires DC current and therefore will not work with this circuit. Don't be tempted to supply the 12 V power supply from a dimmer such as this. It won't like it. See the linked article for more information.
Now, if you touch the touch plate, the bulb glows dimly. On second touch, the bulb gives medium light. At the third touch, the bulb is driven fully and another touch puts off the light. This sensitive touch light dimmer circuit uses minimum external components and can be used for 110V or 220V AC by simply changing some external components . The size and shape of the touch-sensitive area depend on your lamp design and personal preferences. When designing the touch-sensitive area, consider the following factors: Size: The touch-sensitive area should be large enough to accommodate a human finger comfortably. A diameter of around 1 inch (25 mm) is usually sufficient. (In the following images, a 220 ฮฉ resistor is shown. But it could be a good idea to use a larger value like a 470 ฮฉ resistor to make sure your LED can handle the current.) Step 3: Place The LED And Touchpad. Now, you're going to connect the LED and the touch-sensing part. For the touch-sensing part, you'll need two exposed wires.
Touch Lamp Circuit: A Comprehensive Guide Circuit Diagram
a Touch Dimmer Switch using Arduino. The Touch Dimmer Switch Circuit is implemented using a Touch Sensor. This sensors are activated with the touch of human skin or a stylus holding an electrical charge. Fig -2: Touch Sensor 1.3 Aurdino In default the Arduino is not equipped with a display to visualize measuring-data, for example from your Now let us assemble all the components and make a switching circuit. A touch sensor is a touch-sensitive module which has 3 input/output pins. Power up this module by connecting the Vcc pin and ground pin to the 5V and ground of the Arduino. Connect the SIG or OUT pin of this module to the pin8 of the Arduino.
