Arduino Basics

  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/...
