Frequently asked questions
How do I use it with the Arduino IDE?
Upload the ArduinoISP sketch to the UNO, fit the shield, then select Tools > Programmer > Arduino as ISP and run Burn Bootloader. Check the target wiring and fuse settings before burning.
Which signals connect to the target chip?
The ISP header carries MOSI, MISO, SCK, RESET, VCC and GND. Connect them to the matching pins of the target chip and use the same supply voltage for the target.
