Step 3: Connect the potentiometer terminal 3 to +5V VCC on the Arduino. Step 4: And terminal 2 is connected to the A0 pin of the Arduino Uno board. You can read the output from terminal 2 of the potentiometer. How does a potentiometer light up an LED? When you rotate the potentiomete...
In this guide, you will learn how to control an RGB LED using an Arduino. An RGB (Red-Green-Blue) LED can produce a variety of colors by mixing different intensities of red, green, and blue light. You will learn to create a basic Arduino RGB LED circuit and cycle through some basic ...
Introduction: How to Make LEDs Flash to Music With an Arduino This is a guide to make an LED flashing circuit that "beats" to an mp3 file on your computer, which can add an awesome effect to any sound-related device, or even your room (if you extend the concept with LED drivers or ...
How to Stop Climate Change: The Easy Way; Changing Your Light Bulbs May Not Be Enough to Save a Single Polar Bear, but There Are Things We Can Do Collectiv... We have about 100 months left. If global greenhouse gas emissions have not begun to decline by the end of 2015, then our ...
In this Arduino LCD Tutorial we will learn how to connect an LCD (Liquid Crystal Display) to the Arduino board. LCDs like these are...
electronic involves an Arduino microprocessor, a sound trigger, and a reed switch is around 20 dollars with the most expensive component being the Arduino microprocessor. In the lab we often use the 640 Einstein flash on the 1/256 power setting which the students measure to be 195 microse...
In this tutorial, we will not try to control any large appliances for the sake of simplicity. We will stick to LEDs that you can connect directly to the Arduino. Just pretend that the LED is an appliance! The first step: Install The Arduino IDE:The Arduino IDE is an app that you can...

The display has backlight functionality which is commonly in white or blue in colour. 5V is given to backlight with 330 ohm current limiting resistor. Pins 7, 6, 5, 4 and 3 are connected to the digital pins of the display. It is not mandatory to know how the arduino communicates with...
Inputsandoutputsare pins on the Arduino that you can use to either get information into the Arduino (input) or make things happen outside the Arduino (output). For example, if you connect an LED to an output you can turn the light on and off by using thedigitalWrite()command in your ...
