+   Inkplate6COLOR_Read_Touchpads example for Soldered Inkplate6COLOR
+   For this example you will need only a micro USB cable and Inkplate6COLOR.
+   Select "e-radionica Inkplate6COLOR" or "Soldered Inkplate6COLOR" from Tools -> Board menu.
+   Don't have "e-radionica Inkplate6COLOR" or "Soldered Inkplate6COLOR" option? Follow our tutorial and add it:
+   https://soldered.com/learn/add-inkplate-6-board-definition-to-arduino-ide/
+
+   This example will show you how you can use the built-in touchpads (on PCB marked with numbers 1, 2 and 3).
+   These are basically touch sensitive switches. You can read state each of these with function readTouchpad()
+   and the argument you need to pass to this function is PAD1 if you want to read the state of touchpad marked
+   as "1" on PCB, PAD2 for second touchpad, PAD3 for third. You can also use numbers as arguments.
+   For that you need to pass number 0 for touchpad that is marked as 1 on the PCB, 1 for the second touchpad and 2 for
+   the third. The function readTouchpad() will return 1 if selected touchpad is pressed, zero if not.
+
+   In this example, if you touch the first pad, it will decrese the number printed on serial, if you touch the third
+   touch pad, it will increase the number, if you touch second touchpad, it will reset the number to zero.
+
+   NOTE: You can not use touch pads when an enclosure is fitted on the Inkplate - they are not that sensitive!
