All things Arduino

Had oodles of fun (sad I know) browsing the sparkfun.com and robotshop.ca online catalogues looking for components for the Auduino I’m planning to build… and getting a bit sidetracked with all sorts of interesting things…

Seeedstudio Electronic Brick – 9 Button KeyPad Module $9.90
Seeedstudio Electronic Brick – 5 Button ADKey Module $5.50

While I’m ultimately planning to cut/etch my own board using Fritzing and the circuit board cutter at Fablab I’ll probably require a:

ProtoBoard – Rectangle Wired 3” – £3.09

and other components to help me stack boards and build things more easily such as the:09282-4_i_ma-2010-06-13-18-31.jpg

ScrewShield – £6.84

and components such as:

Screws 4-40 Thread – £0.65
Standoffs Metal Short – £1.34
Standoffs Metal Long – £2.03

I’ll also need a power source:

Batt2AJST-01-L_i_ma-2010-06-13-18-31.jpg
Polymer Lithium Ion Battery – 2000mAh – £11.65
“…very slim, extremely light weight batteries based on the new Polymer Lithium Ion chemistry.”
LiPoly Fast Charger – 5-12V Input – £13.71
or the more powerful triple stacked version
Polymer Lithium Ion Battery – 6Ah – £27.45

and a larger speaker:

09151-03-L_i_ma-2010-06-13-18-31.jpg09151-01-L_i_ma-2010-06-13-18-31.jpg

Speaker – 0.5W 8Ohm – £1.34

Oh… and MIDI would be really useful:

09595-01_i_ma-2010-06-13-18-31.jpg09595-02_i_ma-2010-06-13-18-31.jpg
MIDI Shield – £13.71
“The MIDI Shield board gives your Arduino access to the powerful MIDI communication protocol

But then there’s a veritable smorgasbord of affordable additional sensor possibilities:

Light to Frequency Converter – TSL235R – £2.95

08940-03-L_i_ma-2010-06-13-18-31.jpg08940-02-L_i_ma-2010-06-13-18-31.jpg
Light Intensity to Frequency IC – £4.09

TEMT6000 Breakout Board – £3.40
Ambient Light Sensor – TEMT6000 – £1.03

09312-1_i_ma-2010-06-13-18-31.jpg09312-3_i_ma-2010-06-13-18-31.jpg
Hall Effect Sensor – £0.65
“Holding a magnet near the sensor will cause the output pin to toggle.”
Could be great for the syncing of the POV display – but equally several could be used to create a rotating magnetic sequencer?

ePIR – £8.21
“Zilog’s ePIR is a fully functional motion-detecting single-board computer (SBC).”
08663-03-L_i_ma-2010-06-13-18-31.jpg08663-01-L_i_ma-2010-06-13-18-31.jpg
Color Light Sensor Evaluation Board – £13.71

and the musician in me thought it useful to have an LFO or two…

09116-03-L_i_ma-2010-06-13-18-31.jpg09116-01-L_i_ma-2010-06-13-18-31.jpg
DS1077 Programmable Oscillator Breakout – 16.2kHz to 133MHz – £3.40
Break Away Headers – Straight– £1.72
“a dual-output, programmable, oscillator requiring no external components for operation.”

And as for extending the Arduino’s inputs and outputs – I think I’m going to run out fairly quickly 😉 – but there’s plenty of suggestions and solutions out there…

An Arduino: Learning article Serial to Parallel Shifting-Out with a 74HC595“At sometime or another you may run out of pins on your Arduino board and need to extend it with shift registers”… – such as:

A Pins in the Arduino post at chiphacker had some interesting suggestions too – including the shift register above and:

I also needed some orange LEDs for the POV Display and found:

5mm Orange LED – £0.15
MINIATURE 3MM PURE ORANGE LED (RC) – £0.075 1+, £0.05 – 100+

Useful resources found on the way – Tom Igoe’s excellent code, circuits, & construction blog – “code and fabrication resources for physical computing and networking”

As if all this wasn’t ‘food-for-thought’ enough I browsed the Eski Ingredients PDF for yet more sensor types and came across capacitive touch sensors“… used extensively in consumer electronic devices like iphones, laptop touchpads and buttons, but they can also be used as localized proximity sensors, or turning non-conductive materials like glass into physical interfaces for all kinds of electronics projects.”… and it’s opened up an entirely new line of enquiry which I’ll need to document in a separate post…

Hmmm… a DIY touch sensitive musical interface…
