Hi everybody;
During one of my first expermints on PIC16F628 using Nigel's Tutorials. I used RED 7-sigment LED connected directly to the PIC. i noticed that the chip is warm and the 7805 regulator is hot, i measured the following:
7805 input = 9vdc Stable
7805 output = 5vdc Stable
PIC output PORTB= 1.6 vdc ( each of all the 8 outputs )
Current flowing to each Segment = 24 mA ( each of all the 8 outputs )
Is that normal or not? I have run the PIC for long time with no more heat but could any thing make butter ?
Thanks
