Arduino Basics

  Description In this tutorial, I will be evaluating Prextron CHAIN blocks – a new system that allows you to connect your sensors and actuators to an Arduino NANO using clever 3D-printed prototyping boards that can be stacked sideways. This very modular system makes it easy to connect, disconnect and replace project components, and eliminate the “rats nest of wires” common to many advanced Arduino projects. CHAIN BLOCKS are open, which means that you can incorporate any of your sensors or actuators to these prototyping boards, and you can decide which specific pin on Arduino you plan to use. The CHAIN BLOCK connections prevent or reduce common connection mistakes, which make them ideal for class-room projects and learning activities. I am going to set up a project to put these CHAIN BLOCKs to the test: When I place my hand in-front of an Ultrasonic sensor, the Arduino will transmit ...

All information within this post was provided by EasyEDA.     Description None of us could deny the fact that we would love with to play with LED’s and lighting stuff. I love to play with LED’s and create attractive lighting effects. This project was a result of such an attempt where I created a stunning RGB light effect using the popular development platform Arduino Nano. Let’s see the circuit, code and instruction on building this project:     Parts Required: An EasyEDA account (free) Arduino Nano (or compatible board) LED strip Dupont wire connectors Custom control board Image source: EasyEDA     Ardui...

  Description This is a fun project that will surely impress anyone you make this for. If you are having a "Disco" themed party, you cannot have a boring old cake. Let me tell you, this is probably the only Arduino project that my wife has ever been willing to be a part of. She did the hard work of putting the cake together, and I, well.... I was in charge of lighting. My biggest fear was that one of the wires would come loose and ruin the event at the most critical moment... While a wire did come loose, I managed to fix it in time before the guests arrived. Ok enough of my monologue, let me show you how to make one of these things.   Parts Required: Arduino UNO (or compatible board) 4 x WS2812-B Programmable Colorful LED Board 330 ohm resistor 4700 uF 16V Electrolytic Capacitor Breadboar...

PART FOUR The Video This is part 4 of my tutorial on designing an Android Phone Bluetooth App using the Android/Processing language. The App sends information to an Arduino via Bluetooth after pressing a button on the phone. The RGB LED attached to the Arduino Uno (or compatible board) will change colour depending on the button being pressed on the phone. The Arduino gains Bluetooth capabilities through the Seeedstudio Bluetooth shield ( which can be found here ). Parts 1-3 of the tutorial were designed to take you step-by-step through designing the app. If you are wondering what you missed, here is a summary: This is what you'll find in partone : Downloading and setting up the Android SDK Downloading the Processing IDE Setting up and preparing the Android device Running through a couple of Processing/Android sketches on an Andoid phone. This is what you will find in part two : Introducing Toasts (display messages) Looking out for BluetoothDevices using BroadcastReceivers Getting ...
