Fading using an Arduino

LED Projects, Projects, PWM Projects / By Ibrar Ayyub

Demonstrates the use of analog output (Pulse Width Modulation (PWM)) to fade an LED. PWM is a technique for getting an analog-like behavior from a digital output by switching it off and on very fast. Circuit An LED connected to digital output pin 9 through a 220-ohm resistor. Schematic image developed using Fritzing. For more circuit

Analog In, Out Serial using Arduino

Projects, PWM Projects / By Ibrar Ayyub

This example shows how to read an analog input pin, map the result to a range from 0 to 255, and then use that result to set the pulsewidth modulation (PWM) of an output pin to dim or brighten an LED. Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect one

Analog Input using Arduino

Projects, PWM Projects / By Ibrar Ayyub

A potentiometer is a simple knob that provides a variable resistance, which you can read into the Arduino board as an analog value. In this example, you’ll connect a poterntiometer to one of the Arduino’s analog inputs to control the rate at which the built-in LED on pin 13 blinks. Circuit image developed using Fritzing. For

Arduino PMW enabled high power shield or non-shield on the cheap

PWM Projects / By Ibrar Ayyub

Micro controllers are great, but have you ever wanted to control something bigger then, lets say an LED? If you have, look no further (unless you want more then 0.6Amps for 4 channels, or 2.4Amps for 1 channel), unless you don’t mind spending more money. This instructable will be all about building your own, preferably

Controlling a ton of servos – TLC5940 + Arduino

PWM Projects / By Ibrar Ayyub

This is something we have been asked a lot about. How do I control a ton of Servo motors with my arduino? Well… using the TLC5940 is one way. And this nice break outboard from sparkfun makes connecting a ton of servos easy. The output pins on the board are all setup and spaced to

Arduino Based LED Dimmer using PWM

PWM Projects / By Ibrar Ayyub

This LED DIMMER is an Arduino Uno based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained below. Before we get start building a 1 Watt LED Dimmer circuit, first consider a simple circuit as shown in figure below. Now if the switch in the figure is closed continuously over

Talking Pumpkin

Game – Entertainment Projects, Home Automation Projects, PWM Projects, Sensor – Transducer – Detector Projects, Sound – Audio Projects / By Ibrar Ayyub

So my boss came to me one last week and said he wanted to scare the trick-or-treaters who came to his home, and the kids who would come to work during a special Halloween Walk the community does. Thus was born the talking pumpkin. In short, I used an Arduino, an SD card read/writer, and
