6 Digit LED Clock

I recently found six 2.3″ red 7 segment displays in my collection which I purchased from Rapid Electronics when they were clearing out non-RoHS stock. Since I have no clock at my work bench I decided to construct one from some prototyping pad board, a Microchip PIC18F26K20 microcontroller and a Dallas DS32KHZ temperature compensated 32.768kHz crystal. The displays I used are SA23-12SRWA, which don’t appear ...

Controlling RGB LED using Arduino and Wi-Fi

In last tutorial, we explained controlling a Robot using Wi-Fi and Arduino, and in this article we are with our next IOT Based Project- RGB LED Flasher using Wi-Fi. Here we have used Arduino and ESP8266 Wi-Fi Module to control the colors of RGB LED, through a Android Phone, over the Wi-Fi. In this RGB Flasher LED, we have used an Android Mobile App named “Blynk”. Blynk is a very compatible app with Arduino, ...

Arduino Based LED Dimmer using PWM

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 a period of time then the bulb will continuously ON during tha ...

8×8 LED Matrix using Arduino

In this project we are going to design an 8x8 LED matrix display, for that we are going to interface an 8x8 LED matrix module with Arduino Uno. An 8x8 LED matrix contains 64 LEDs (Light Emitting Diodes) which are arranged in the form of a matrix, hence the name LED matrix. These matrixes can be made by circuiting 64 LEDs, however that process is time consuming. Now a day they are available in compact forms ...

Arduino Propeller LED Display

You have seen Propellers in Aircrafts or in marine ships, if not in real then in movies for sure. In this session we are going to design a Propeller Display with Arduino, LEDs and a DC motor. In this Propeller Display, text will appear to be rotating in propeller fashion in a circular shape. The propeller display is in a way like LED Matrix. It contains 8 LEDs (Light Emitting Diodes) which are arranged in t ...

DIY 3X3X3 LED Cube with Arduino

In this project we are going to design a 3x3x3 LED CUBE and connect it to Arduino UNO to get different patterns. For a beginner we will start with a simple pattern. A typical 3*3*3 LED cube connected to UNO is shown in the image above, the cube consists of 27 Light Emitting Diodes, these 27 LEDs are arranged in rows and columns forming a cube. There are many types of cubes that can be designed. The simplest ...

Interfacing 8×8 LED Matrix with Arduino

LED matrix displays can be used to display almost anything. Most modern LED sign boards uses various types of matrix boards with controllers. In this tutorial we are going to interface a single color 8×8 LED matrix with Arduino and display a few characters in it. 8×8 matrix consists of 64 dots or pixels. There is a LED for each pixel and these LEDs are connected to total of 16 pins. You can identify the pin ...

Clap activated LED strip

This Instructable shows you how to build a clap activated LED strip. The whole project is based on the Adafruit's Secret Knock Activated Drawer Lock, where the user can record a secret knock pattern which will open the lock inside the drawer. I thought that I could use this to siwtch an LED strip on and off with a handclap pattern. So let's begin! Step 1: Components I used the following components to build ...
