w_2_success after burning_2




I figured out why my microcontroller was burned at the first attempt. Comparing pictures of success and ones of being burned shows the reason. The failed one is circuited wrong. One end should be connected to power and the other to the ground. But the failed one did not give the circuit way out. That is what made the circuit banged.
On the successful circuit, I had current flowing indefinitely, finally 2 LEDs blinking.

The other issue I have been sticking around was how to supply a microcontroller with power. I thought "input" in a pic programming and 5-volt power supply in the diagram was identical. So I kept trying to power the microcontroller with only one input - that is onto the middle of microcontroller. I was wrong.

After a few weeks of lazy and foolish attempts, I finally made it. I owe many thnaks to Kazu.

You must have unequal voltage to have electricity happily tour around a circuit. I was among few who didn't realize it.
