    current measurement over time

    I have a RC servo towerPro sg90 connected to Arduino, to measure the current I have put 1 ohm shunt resistor between servo GND and power ground. Then I did a analogRead on the resistor, when servo sweep between 0 -180. I am getting following values out of my analogRead. So in total I have 180...

    HW Interface to detect Radio Control Receiver PWM signal

    I am using an Arduino Pro Mini to detect a PWM signal from a radio control receiver. The input pin on the Arduino is supposed to be limited to 20mA current with a max current of 40mA. I plan on using a 220 ohm resistor in the circuit. Do I need a .1uF cap to ground (and what kind of cap)...
