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 ...

  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 Part 3: Transmit a known 433 Mhz RF code to a 433 Mhz RF device - ** you are here ** 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 3: RF Remote Control Emulation In the first tutorial , I introduced the 433 MHz Transmitter and Receiver with a simple sketch to test their functionality. In the second tutorial , the 433MHz receiver was used to receive a signal from an RF remote. The RF remote signal was coded based on the pattern and length of its HIGH and LOW signals. The signals received by the remote can be described by the code below:   Code comparison table ...
