Multiple switches on Arduino analog pin schematic


Posted on Feb 5, 2014

Connect a 5 way button/joystick to an Arduino using a single analog pin and wanted to quickly simulate it to verify my calculations before I went and soldered everything. The voltages for the six states are 0, 1, 2, 3, 4, 5. The 4V being shown in the photo is because one of the switches is pressed. I solved the problem of the all switches open state voltage by adding in the 1Mohm R7, which was okay for me since

I wasn`t making something battery operated. Some people prefer to turn on the internal pull-up on the chip.
