![]() Virtual Reality/ Gesture control using Arduino.We have already done few projects using Processing and you can check them out by clicking on the links below. It is an Open-Source development application and can be easily downloaded and put to use for developing interesting projects using Arduino or other Microcontrollers since it can develop android application and system applications. The Android application for this project was created using the Processing software. So let’s take a look at how the Android application is created and how you can use it on your smartphone to control the 8x8 LED matrix. 8x8 LED Matrix Interfacing with AVR MicrocontrollerĬreating the Android Application using Processing:īefore we can start programming our Arduino, we should know what type of data we will receive form the mobile phone to respond back to it.Scrolling Text Display on 8x8 LED Matrix using Arduino.Controlling 8x8 LED Matrix with Raspberry Pi.However due to the its complexity it is recommended to either buy a 8x8 Display module or use the PCBĨx8 matrix is very useful display module and can be used in many cool projects: The ISET pin of MAX7219 is pulled high through a 20k Resistor.įor this project I have fabricated a PCB, you can get the design file of the PCB and use the same or build the circuit on a breadboard. The digital pins D5 to D7 is connected to the MAX7219 IC to send and receive data through SPI communication. The Tx and Rx pins of the Bluetooth module is connected to D11 and D10 of the Arduino to enable serial connection. This Raw voltage is then regulated to +5V which is supplied to the Bluetooth module and the MAX7219 IC. The whole project is powered by a 12V adapter, which is directly given to the Raw pin of the Arduino Board. We will use the same schematics to develop a PCB from it and fabricate it using EasyEDA. The circuit Diagram this Bluetooth controlled LED board built using the EasyEDA application. This enables the user to create custom designs with ease and display it on the LED display, sounds interesting right?!! So let’s get started. ![]() A unique feature of this project is its android application which allows the user to control all the 64 LEDs individually from the mobile phone. So in this project we are going to build a Bluetooth controlled Sign board using an 8*8 Matrix display. But these sign boards are often boring and cannot be configured as per our interest from time to time. Be it the long stretched highways or your doctors front door, we have sign boards placed everywhere to provide us information.
