Arduino as ISP - Using two arduinos

Using Arduino Microcontrollers

juanps90:
Hello, I have a question regarding the installation of a bootloader using two arduinos.

  1. Does the arduino used as programmer need to have a preinstalled bootloader?
    Yes, as there has to be a way to upload the arduinoISP sketch into the board so it will become a programmer board.
  2. "On the Arduino Uno, you'll need to connect a 10 uF capacitor between reset and ground (after uploading the ArduinoISP sketch).": Do I need to connect a capacitor to EACH arduino ( ie two capacitors ) ?
    No, just the board that is loaded with the arduinoISP sketch.
  3. I see other howtos show different connection diagrams involving ICSP connectors. Are they necesssary?
    They should all be doing the same function of wiring the ICSP signals from the programmer board to the target board. Show a link if one is confusing you.

Thank you very much !
