Arduino Power Tester

This code displays the power of the Arduino’s on-board 3.3v power supply. It’s a good example of Arduino to TouchShield communication and TouchShield graphics. Two files are part of this project, one to compile and upload to the Arduino, one to compile and upload to the TouchShield.

Parts for Arduino Power Tester:

Arduino Duemilanove
TouchShield Stealth

Files for Arduino Power Tester.

This can only measure up to 5V because it is going into the micro controller. Higher voltages could damage the chip.

FYi to other readers, you could make this measure a wider range of voltages by using a resistor divider network, and then multiplying the result you get from the Analog input pin accordingly. I have my Arduino measure up to about 20VDC safely.
