In this project, a simple variable voltage regulator is implemented. LM317 is used to regulate the output voltage.
The output voltage of LM317 is adjustable as long as it maintains a difference between input voltage and output voltage lower than 40 Volts.
Voltage reference is 1.25 (the band-gap voltage).
