In MCU-based projects, this design uses a single push button to switch on and switch off 5-V and 15-V supplies in sequence.

Switches and push buttons need debouncing. It is straightforward to do this with software, using a library. The advantages of the Switch library are: External pull-up resistors are not required.

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...
