MCP41HVX1 Digital Potentiometer for Arduino: The MCP41HVX1 family of digital potentiometers (aka DigiPots) are devices that mimic the function of an analog potentiometer and are controlled thru SPI. The AD5251/AD5252 are dual-channel, I2C, nonvolatile memory, digi Arduino library for I2C digital potentiometer AD5263 and compatibles. I wrote a program to increment the 4 bit value every 1 second, and I used an analog pin to read the circuit output. The component has been attached to my Arduino UNO board and I am trying to control the volume using the "Wire" library. Part one covered the AD8403 digital pot. 1k is a must as I am replacing a mechanical potentiometer and trailfitting some higher value messed up the item. Interfacing X9C103S Digital Potentiometer Module with Arduino . Using Arduino's I2C Wire Library, the digital pot will step through 64 levels of resistance, fading an LED. Programming is accomplished by an I²C-compatible interface, which can operate at speeds of up to 400kHz. Hi Everyone, I'm trying to use an Arduino to control a peltier element, and was searching the forums when I found a link to this (Arduino Controlled Digital Potentiometer); Would I be correct in saying that if I replaced the terminals of the LED with the terminals of the peltier element, that it would then be controllable by the Arduino? Or am I taking a too simplistic I'm trying to see if I could use the I2C protocol to be able to read a potentiometer connected through an ADC that is connected through I2C with the microcontroller. The link I gave above has some sample code. I'm not sure how to wire the two together in terms of power connections. What I want to do is the use an arduino connected to one analog Data Sheet AD5251 /AD5252 Dual 64-/256-Position I2C Nonvolatile Memory Digital Potentiometers Rev.
