Adjust the 10K potentiometer to adjust display contrast. You can power the Arduino from USB or via DC jack with 9 V batteries. Four 2 watt resistors will dissipate the heat evenly than using one 2.5 ohm resistor with 8 10 watt resistor. Measuring voltage in a circuit with PWM forum.arduino.cc The voltage in a PWM circuit is constantly changing, so the only "proper" way to measure it is to use an oscilloscope. But then, you will find that it switches constantly between about Vcc and 0. If you want to measure an average voltage, then a voltmeter that is very slow to respond (like an old analog needle type voltmeter) is another useful way.
