Arduino library for reading values from a Dell power supply via 1 wire protocol
Reads the data from a dell charger using OneWire and parses the wattage, voltage, and current
Connect the center pin of the Dell power supply to the desired Arduino I/O pin
Add a 4.7K pull-up resistor between the tiny center pin of the Dell power supply and the Arduino +5V rail
Connect the ground pin of the Dell power supply to the Arduino GND
Do not connect the 19.5V pin of the Dell power supply to the Arduino!!!!
