AVR programming language Arduino can be simulated and debugged with Proteus

Here is the Arduino program:

Press the "triangle" icon and press Shift at the same time, and you can see where the HEX of the 0018 version of the Arduino programming software has gone. Look at the compilation result area in the figure above, the part I shaded, and you can see the directory where the HEX is hidden. Put the HEX file into the ATMEGA168 microcontroller of Proteus, press the run button in Proteus , and you can see that the combination of Arduino and Proteus has achieved the task requirements. You can learn it without spending a penny. It is an avr programming software highly praised by foreign robot enthusiasts.

Note the correspondence between the Arduino controller digital and analog interface numbers and the AVR microcontroller pins.
