I looked at the code for Arduino ISP and it seems there are 2 possible pin sets: #ifndef ARDUINO_HOODLOADER2 #define RESET 10 // Use pin 10 to reset the target rather than SS #define LED_HB 9 #define LED_ERR 8 #define LED_PMODE 7 and #define RESET 4 #define LED_HB 7 #define LED…

building custom ISP shield, what pin for LEDs?
