ATmega32 Switch Toggle Program

ATMega32 switch code is extremely simple to implement, and this article looks into how to write the code to make an LED light up when a switch is pressed. The atmega32-switch-code.c program tests the switch input to the ATMega32 Development System. There are many ways to write the code, but I have chosen the simplest way possible so everyone can understand. Therefore, instead of using “case”, I am using “if ...
