  • @TVCatchup rules, OK? I have a TV licence for both my houses, which means that I can watch TV live on my iPhone, for free! Unbelieveable! :D #
  • Haha! If only more girls thought like this – "If you don't send your boyfriend naked pictures, then I feel bad for him." Rhiana, May 2009 :P #

Arduino, Breadboard and PCB Basics

Thursday, November 26th, 2009

Well after a week of just making the LED on one of my Arduinos flash, I decided to get back in touch with some basic electronics and where best to find electronic components than in old electronic equipment?

I spent all of last weekend going through my roof and digging out anything with potentiometers, resistors, LDRs, infra-red, motors, solenoids and lasers and taking it apart to try and get some ideas for interactivity. Turns out that I found 2 computers, 2 additional graphics cards, 3 stereos, a PSU, an amplifier and a laser printer. Needless to say my mother wasn’t happy when she saw the state of the roof:

However, I struck gold when I found my old ‘Cybot’, built from a week-by-week magazine collection, Real Robots:

Wow – he had it all! The LDRs, the ultra-sonic sensors, the infra-red, the LEDs, the motors and the ‘line-following’ snout. So i killed him. What’s left of him is sitting in an anti-static bag in front of me.

So I then started to read more into electronics. I was quite good at electronics in college, but then it did just consist of soldering a couple of resistors onto a pre-made PCB and plugging in a battery to test fuses. Boring! I know what component is what and its basic function, but I decided to look into things like how a transistor works and the tolerances of a relay and what a J-K flip-flop chip does. I looked at logic circuits in more detail than I realised and I think I now have enough knowledge to start building my own circuits for the Arduino. Starting off nice and simply, hooking up an LDR to the board and getting a reading.

Easy! For my new idea, the hardware side of things only requires 3 or 6 LDRs, 2 ultra-sonic sensors, 2 potentiometers, 6 PTM switches and a microphone. My final year project is, as yet, undecided! An update is imminent…
