10-Minute Buttons With Indicator

Perfectly simple Buttons for quick DIY Projects from spare Parts everyone has.

Supplies

3D Printer

Soldering Iron

Standart Round 5mm Led

Standart Button 5x5mm

Standart Resistor 10k for the Led (quite high)

Step 1: 3D-Print

The fit comes out perfectly on a Prusa, no glue or plastic soldering required. Here are the files for using:

Step 2:

While the case is printing its time to solder. Just cut a perfboard, add the components, solder ground together and one pin to one button or led. Its best to use thin wires that there is enough space. Sorry i don't have a schematic.

Step 3:

Assembling. Just put the 3 parts together and connect it to some Project. The left pin at the controller is GROUND. After that there are the 3 buttons as expected and then the Led which can handle 5V due to the resister. The buttons need a Pull-Up Resistor which can be mostly internal in the MCU.
