Burning Arduino Uno Bootloader Answered

I am planning to burn a bootloader onto an Arduino Uno using a Uno as an ISP. The instructions here: http://arduino.cc/en/Tutorial/ArduinoISP  say to put a 10 mf capacitor between reset and ground. But they to not say which Uno to put the capacitor on. Am I correct that it should be on the Uno to be programmed and not the programmer?


The forums are retiring in 2021 and are now closed for new topics and comments.

Wire the capacitor on the chip that you are programming or trying to flash with the bootloader. I think it prevents the new chip from resetting itself while being programmed causing the process to fail. Good luck.
