Arduino Course for Absolute Beginners Reading Analog Pins and Converting the Input to a Voltage. In the last lesson you learned about using the analogRead() function to collect data from a sensor connected to one of the Arduino analog pins.
Reading a Variable Reluctance Sensor - Arduino Forum
A thermistor indicates temperature by a change in electrical resistance. The analog input pins of the Arduino can only measure voltage, so the electrical resistance of a thermistor cannot be measured directly1. A simple technique for converting the (variable) resistance of …

Variable power supply (0-10V, 1A) - Arduino Blog
The code statement int reading=analogRead(sensor) reads the sensor output voltage and place the numeric value in variable reading. I divided the reading by 4. This is because arduino analog channel outputs analog value ranging from 0 to 1023.

/21/2015Variable power supply (0-10V, 1A) Standard. Here’s my latest project. I’ve spent the last week researching, prototyping and building a variable power supply to use with my other electronics projects. If we use Arduino, the voltage is limited to 5V. Since we want to have a power supply that goes from 0 to 10V we need something
