Sensing Part 1: Potentiometers

Description

In this lab, three LEDs were controlled using 3 potentiometers. In the beginning exercises, an LED's brightness was controlled using the rotational position of the potentiometer to change the input voltage. This concept of changing the input voltage using a potentiometer in order to change an output was used to create the final concept for this lab.

Lab3: Potentiometers (3LEDs & 3POTs)

Submitted by euiyoungkim on Mon, 02/18/2013 - 22:41

 

 

Description

I made diffusers to mix RGB colors by covering LED lights with transparent plastic tube, as well as a tiny glass. I use 3 independent potentiometers to 3 RGB LEDs to adjust the brightness of each color manually.

Lab 3: Red/Blue blending with potentiometer

Submitted by alexis.taylor on Mon, 02/18/2013 - 19:04

Description

For this lab, I first extended the circuit to include one potentiometer to control LED blinking speed. I then extended the circuit to include another potentiometer, and tried out code to use one pot to control blinking and one to control brightness. Since I only have two pots, I decided to write a code that uses one pot to control blinking, and the other to map an LED at full brightness each end of the range to blend two colors - when one LED is at full, the other is at zero and vice-versa.

Components Used

1 arduino uno R3 (5V)

Description

In this lab assignment I have created a circut that lets you control three LED's with two potentiometers. One potentiometer controls the brightness of all three LED's and the other potentiometer controls the blinking speed of all three LED's.

Triple Blink and Fade

Submitted by jmscott212 on Mon, 02/18/2013 - 17:12

Description: 

I combined the blink code and fade code so that one Potentiometer controlled the blink of all 3 LEDs and another Potentiometer controlled fad of all 3 LEDs.

 

Components Used:

1- Arduino Uno

1- Breadboard

3- 220 Ω Resistor

3- Potentiometers

3- LEDs (Blue, Green, Red)

1- Diffuser Sculpture

EGGuino with Pots

Submitted by deb on Sun, 02/17/2013 - 20:37

Description

In this assignment I set my existing "EGGuino" diffuser project to be controlled with 3 potentiometers (pots). Each separate pot uses Arduino's analog pins to control the brightness of 3 separate LEDs. If the user wants to produce a specific color, they can adjust the pots as they reference the serial, which continuously streams the value of each pot. The serial will print the name of classic colors (e.g.

Description

Three potentiometers are mapped independently to three LEDs to control their brightness (for mixing) and blinking rate. Fastest blinking occurs when a single LED is on, at its lowest brightness. Slowest blinking occurs when all three LEDs are on, at their maximum brightness.

Components Used

1- Arduino Uno

1- Breadboard

3- 220 Ω Resistor

3- Potentiometers

1- Green LED

1- Blue LED
