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 ...

  My attention is drawn towards the noise behind me.... I cannot believe it. There it is.   The Arduino is taking a SELFIE !!   How did this happen?   Well actually, it is not that difficult for an Arduino.   I found out that my Canon Powershot SX50 HS camera has a port on the side for a remote switch. In the "Optional Accessories" section of the camera brochure , it identifies the remote switch model as RS-60E3 . I then looked up the model number on this website to find out the size of the jack (3 core, 2.5mm), and the pinout (Ground, focus and shutter) required to emulate the remote switch. Once I had this information, I was able to solder some really long wires to the jack and connect up the circuit (as described below).   And before I knew it, the Arduino was taking Selfies !!!   Warning : Any circuit you build for your camera (including this one) i...

WARNING: Mishandling or incorrect or improper use of relays could result in serious personal injury or DEATH possible physical damage of the product faulty operation or create serious/dangerous hazards. Please make sure that you read and understand how your relay/relay module board works, the voltage and current it is rated for, and the risks involved in your project BEFORE you even attempt to start putting it together. Seek professional and qualified assistance BEFORE you undertake ANY high power projects. If you choose to follow the instructions in this tutorial, you do so at your own risk. I am not an electrician, and am not a qualified electrical engineer - so please do your research and seek advice BEFORE undertaking a project using a relay. Please check your connections and test them BEFORE turning the power on. I accept no responsibility for your project, or the risk/damage/...
