Tiny servo controller for HeartBeat project using a ATtiny13A 8-pin microcontroller.
It reads the analog value of pin B3 for heart rate adjustment. Outputs pulsed signals for controlling 3 hobby servos on pins B0, B1 and B2.
With the avr toolchain installed, just run make and it should generate the .hex file. Run make prog for programming the chip after building automatically.
