Proteus is a software tool that allows simulation of various circuits including microcontroller based ones. You can complete entire project with simulator including hardware and software parts. And only then you can move towards manufacturing real device. This page is dedicated only to PIC16F84 microcontroller projects where you can download ready to simulate about 31 complete project.
Projects include implementation of popular interfaces like LCD, Timers, EEPROM writing, Interrupts, I2C and 1-wire communication, motor control and so on. Each project include Proteus project file and microcontroller hex file that has to be attached to model to start simulate.
