Arduino Basics

  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...

Project Description In this project, your heart will control a mesmerising LED sequence on a 5 metre Neopixel LED strip with a ws2812B chipset . Every heart beat will trigger a LED animation that will keep you captivated and attached to your Arduino for ages. The good thing about this project is that it is relatively easy to set up, and requires no soldering. The hardest part is downloading and installing the FastLED library into the Arduino IDE, but that in itself is not too difficult. The inspiration and idea behind this project came from Ali Murtaza , who wanted to know how to get an LED strip to pulse to his heart beat. &nbsp Have a look at the video below to see this project in action.       The Video       Parts Required: Arduino UNO (or compatible board) NeoPixel Digital RGB LED Weatherpr...

There are 4 parts to this tutorial: Part 1: Testing the 433 MHz RF transmitter and receiver Part 2: Receive and interpret code from an RF remote - ** you are here ** Part 3: Transmit a known 433 Mhz RF code to a 433 Mhz RF device Part 4: Record and play back a 433 Mhz RF remote signal To get the most out of this tutorial - it is best to start at tutorial Part 1 , and then progress to Part 2 then Part 3 and then do Part 4 last. Doing the RF tutorials in this order will help you to understand the process better. Project 2: RF Remote Copy In the previous project , we transmitted a signal wirelessly from one Arduino to another. It was there to help troubleshoot communication between the modules. It was important to start with a very short distance (1-2 cm) and then move the RF modules further apart to test the range. The range can be extended by soldering an antenna to the module, or by experimenting with different voltage supplies to the modules (making sure to keep wi...

Introduction: The HC-SR04 Ultrasonic Sensor is a very affordable proximity/distance sensor that has been used mainly for object avoidance in various robotics projects . It essentially gives your Arduino eyes / spacial awareness and can prevent your robot from crashing or falling off a table. It has also been used in turret applications, water level sensing, and even as a parking sensor. This simple project will use the HC-SR04 sensor with an Arduino and a Processing sketch to provide a neat little interactive display on your computer screen. Parts Required: Freetronics Eleven or any compatible Arduino. HC-SR04 Ultrasonic Sensor Mini Breadboard 4.5cm x 3.5cm Protoshield and female header pins (not essential - but makes it more tidy) Wires to connect it all together The Video: The Arduino Sketch:      The above sketch was created using Fritzing . Arduino Code: You can download the Arduino IDE from this site . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19...
