Arduino AC Voltage Dimmer (Variable Resistor? PWM?)
Using a Variable Resistor as a Control . Goals. Push button and other switches are great input devices for some applications. For some things a knob that can be turned is a much better Human Machine Interface (HMI). The volume control on a radio is a good example.

Using a variable resistor with a microcontroller A/D
Arduino Tutorial Arduino inputs. Intro. Starting. Lesson 0. Lesson 1. Lesson 2 . Lesson 3 . Lesson 4 . Lesson 5 #6 - LEDs. LCDs. Sure we could use a variable to hold the result from digitalRead() With the pull-up resistor configuration, what is the value read by digitalRead() when the button is released?
Variable Resistance output from Microcontroller - Arduino
A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it …
duino - 120v variable resistor controlled by 5v
Share on Tumblr Variable Resistor or Potentiometer gives different range of Resistance value in circuit and used in many applications like volume control for Audio circuit, Television, Oscillators, Home Electrical appliance etc. . , This Article describes what is digital …
Arduino – Servo motor control rotation with Variable Resistor
Build variable resistor controlled by Arduino. Ask Question 1 $\begingroup$ I would like to build a variable resistor that can be controlled by Arduino. My plan is to vary resistance between the two values, i. e. , 1 ohm to 10ohm, to continuously change the load for a small wind turbine. The resistances are for dissipating the power from the

An Experiment by Simon Monk Before we go ahead and use the LEDs, you can try a little experiment using just the variable resistor also known as a potentiometer (often called a 'pot' for short) and the Arduino Serial Monitor.
Control the Brightness of an LCD Backlight using PWM with
Controlling a Digital Potentiometer Using SPI. For example, in this tutorial we will be using each variable resistor as a voltage divider by pulling one side pin (pin B) high, pulling another side pin (pin A) low and taking the variable voltage output of the center pin (Wiper).
