Help with shrinking program on to Tiny85

Using Arduino Microcontrollers

Hi,

Just to check your connections,
int switchPin = 3; // leg 3 on the ATTiny85
int led1Pin = 0; // leg 5
int led2Pin = 1; // leg 6
int led3Pin = 2; // leg 7 but it's NOT PWM capable, so your analogWrites won't work; suggest you move this one to leg 2 or 3 (D3 or D4 if you still need to analogWrite)

Cheers ! Geoff
