capacitive touch screen for arduino

Now on the other side of the breakout board we have 12 pins that you can connect to anything you like, soda cans, fruits, aluminum foil and many other things. Download the ZIP file and extract the MPR121 folder out of the ZIP into your “libraries” folder in the Arduino ide working environment. Capacitive Proximity sensors: Capacitive proximity sensors on the other hand can detect dielectric materials such as liquid, plastic, glass, wood and granulated substances as long as it has a dielectric constant of 1.2 or more. for(int i=0; i “Examples” scroll till you see the “MPR121” and choose the “SimpleTouch” example from it. It has way more resolution than a black and white 128x64 display. Line 16 to 41 in the code – The above piece of code will execute only if we had issues initiating the MPR121 and it will output the error type and will loop forever (while (1)) – not allowing any other part of the code to run. MPR121.updateTouchData(); – We again update the data from the sensor, to get the current state of each of the input pins. Attached below, uou will find a zip file that contains the Arduino code for the Capacitive-Touch Arduino Keyboard Piano. This will allow us to create a switch without any moving parts and requires only an Arduino board and one of the capacitive touch sensors shown below.
