Arduino Leonardo Pro Micro case with 2 tactile push buttons

Case for Arduino Leonardo Pro Micro Micro usb version 3-6V PCB size 33.4mm x 18.3mm fits only without soldered connector pins! buttons: Tactile Push Button H2.0MM + 5.2X5.2MM +printed button heads I have printed all components laid on their flat side without any support and adhesion. wiring is not yet soldered wires should be pulled in the central hole to the PCB Cover is tight enough so glue is not needed there. update: for wiring I had to cut the hole's upper part from O to U shape. Fortunately it did not made the wall - which supports buttons - too weak Buttons' lower contacts are bridged by a small but solid wire (a part of regular resistor's wire.) This way buttons are always the same position. I have put 2 small ~4x4mm pieces of carton paper (like paper box of a medicine) There is no need to use any glue this way. buttons work like a charm :) +1 thing: I did not use pull_up resistors because in this type of micro controller there are programmable pull_up resistors. They can be turned on this way: ... pinMode(button1Pin, INPUT_PULLUP); pinMode(button2Pin, INPUT_PULLUP); ...
