But the timing has to be right, hold down the reset, select the program from the IDE, when it says loading, count one two three, and release the reset.
I have tried this ! It's really do work well ! But the timing really have to be correct. Have to release the RESET button once the IDE shows 'uploading..'
Thanks ! Finally I understand why is there a cap there- to bring the RESET High and LOW.
When I want to upload a new sketch, the we should RESET our microcontroller so that the previous sketch is deleted and pull the RESET HIGH to allow the new program to load into ?
Am I correct ?
