MCHEN 9 PCS Digital Touch Capacitive Sensor Switch Module for Arduino with 30p Dupont Cable

in this tutorial I'm going to show you how to control the onboard LED with a touch sensor for this tutorial you'll need an Arduino the touch sensor and three jumper wires male-to-female if you don't have these jumper wires you can also use a breadboard and three jumper wires male-to-male the first step is to connect your jumper wires to the touch sensor PCB the touch sensor is actually a resistor when you touch the PCB the resistance will increase therefore the PCB can detect that you've touched the sensor and sends the signal HIGH to the Arduino now it's time to connect our touch sensor to the Arduino the red wire is connected to the 5V the blue wire is connected to the ground and the green wire is connected to pin 8 our circuit is now complete let's have a look at the code the code is pretty straightforward if you look at line 19 we set pin number 8 as an input on line 20, we use th
