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...

In the previous two parts of the this tutorial, we went through a number of simple sketches to get you acquainted with the way that the Arduino handles various data types when passed through the Serial COM port. Here are the main themes from part ONE : Stage One:   Echoing data with the Arduino Stage Two: Using Delimiters to split data. Stage Three: Arduino Maths, simple addition Stage Four: Sending a double to an Arduino, and then doubling it. Stage Five: Sending Sensor data from the Arduino to the Serial Monitor Here are the main themes from Part TWO : Stage Six: ......A simple Processing Sketch Stage Seven:  Arduino and Processing join forces for more fun Stage Eight: A simple project that shows Serial communication from Arduino to Processing In Part Three - we will reverse the direction of communication and get Processing to send data to the Arduino via a USB cable, Stage Nine: A simple processing sketch that switches an LED on the Arduino Stage Ten:   A processing...
