Arduino Playground - ArduinoPinCurrentLimitations
Smiley's Workshop — AVR C Programming Workshop Series - Part 10. Last month, we were introduced to the Arduino and made an LED blink. I’m betting that many of you went off to the Arduino website and played around with other examples.
Measuring Voltage with Arduino - Starting Electronics
On the Arduino board, these pins have an ‘A’ in front of their label (A0 through A5) to indicate these pins can read analog voltages. ADCs can vary greatly between microcontroller. The ADC on the Arduino is a 10-bit ADC meaning it has the ability to detect 1,024 (2^10) discrete analog levels.

- 10 volt analogue output from Arduino
To get a 12V output from an Arduino Uno Board you need to use the Vin and GND pin as terminals. Vin would give the maximum voltage being provided to the board ( if board is supplied 9V then Vin would supply 9V and likewise). This two methods are most used in Electronics for switching/Regulating more then 5 volts. 7. 2k Views View 10

Set up a 50 percent duty cycle PWM signal from the Arduino (depends on your rpm range). If you have an RPM range of 0 - 255 then M3 S127 would give you an approximately 50 percent duty cycle. Then using a voltmeter to measure the output turn the potentiometer until the output reads 5 volts. You also have to set the yellow jumper correctly.

Next was board for input to Arduino OP = oil pressure OT = oil temp WT water Temp V = volts Input board for Arduino uno All connected and testing piezo for alarm, can hear with helmet on.
Precise voltage measurement with an Arduino microcontroller
The truth is that most times we want something in the middle. We would maybe want a voltage of 2. 3 volts. The arduino pins with the squiggly line by them are able to write these in between voltages. These are pins 3,5,6,9,10,11 on the arduino uno. In the world of engineering and electronics, we say that we want an analog voltage.
