Arduino Based power supply

This is my all new DIY power supply. It's based on the ATMega328 micro with the arduino bootloader on it. I used the LM350 as the voltage regulator so I can get 15 volts and about 3 Amps( not that I will ever use 3 amps :D). The LCD is based on the HD44780 driver.

@paulwoody if you want you can give me your email and i will give you more info.

There is 2 switched one is a simple on-off switch the the other is for current measuring.

The current measuring works by putting a small resistor(about 1Ohm) in serial with the circuit you're powering, and by measuring the voltage across the resistor you can calculate the current(V/R=I).

Do you have more inform on the project? What do the buttons do exactly?

Also one thing I could never get my head around how do you measure current consumption exactly?

Looks great anyway!
