has TWO servo or PWM outputs and one (ADC/Digital input or Output) Servo Outputs PB1 and PB4 General I/O PB3
Only uses Timer/Counter1 for OCR1A and OCR1B Does not touch Timer0
LOTS of notes in it for understanding PWM
Personally would like to thank danielfaust for: https://github.com/danielfaust/ATtiny45-ADC-PWM-I2C-RaspberryPi
I just build off it
