Small macropad for any custom button configuration you want using the basic arduino keyboard library using the code below, this is NOT a matrix and uses pins 3-8 on INPUT_PULLUP. they can use any cherry MX switches, all 4 LEDs are in 2 sets of series so the 5V output works just fine for them.the pins on the board will need to be soldered flush with the top side of the board(with the squares and silkscreen silkscreen) so it doesnt block the keys themselves. solder the pin headers, LEDs and switches first then arduino onto the pin headers or it will be difficult to remove and reattach.all the code used is below and can be copy pasted straight onto the board through the arduino IDE.#include <Keyboard.h>void setup() {pinMode(3, INPUT_PULLUP);pinMode(4, INPUT_PULLUP);pinMode(5, INPUT_PULLUP);pinMode(6, INPUT_PULLUP);pinMode(7, INPUT_PULLUP);pinMode(8, INPUT_PULLUP);Serial.begin(9600); }void loop() {Keyboard.begin(); if (digitalRead(3) == 0){ Keyboard.write(0xD1); delay(250); } else if (digitalRead(4) == 0){ Keyboard.write(0xD1); delay(250);} else if (digitalRead(5) == 0){ Keyboard.write(0xD1); delay(250); } else if (digitalRead(6) == 0){ Keyboard.write(0xD1); delay(250);} else if (digitalRead(7) == 0){ Keyboard.write(0xD1); delay(250);} else if (digitalRead(8) == 0){ Keyboard.write(0xD1); delay(250);} Keyboard.end();}
