What is an Arduino?
Arduinos are micro-controller platform boards that work off of package and are programmable with an Arduino IDE over USB. These tiny platforms help you realize any wearable or IoT project. Now, if you have wanted someone to do these projects with, I am right here. Maybe now is a good time to give it a try ? 🙂
Programmable Wearable Pins
I am starting off with a basic programmable sewable project. This shall only need a micro-controller called Arduino Gemma, few RGB or NeoPixels (smart program controlled LEDs), a battery to power up our circuit and a conductive thread to stitch our electronic circuit together on our wearable pin.
*** NOTE: This project shall not have any connectivity to our smartphones such as Bluetooth or WiFi, that the DIY project in the link above would require. Because? Basics First ! 🙂 ***
Note : You could “wash” your wearable circuitry *but with the battery removed *
- Instructions to install Arduino Desktop IDE are available on this page. Select your system type – Windows, MAC etc and get started or you could use the online IDE.
- Install the driver for Windows (MAC and Linux users don’t need to do this). Use the instructions under “Windows Driver Installation” on this reference page
- To be able to program a Gemma chip using the Arduino IDE we will need a plugin. Instructions to add this plugin are documented here.
 The Arduino Chip :
If you just want to add glow circuitry to your clothes, a chain or a headband or any wearable – all you need is an Arduino Gemma chip. However, if you wish the glow patterns to be controlled via Bluetooth using your smartphone or computer you would need a Arduino Flora Bluefruit LE .
The entire sensor kit contains Gemma along with four sewable bright RGB pixels, a motion sensor, a switch, a light sensor, a piezo, a rechargeable battery and charger, 2-ply conductive thread, alligator clips to help you test out your circuit, and a USB cable for programming GEMMA.
Gemma : $9.95 Flora : $17.50 (has bluetooth - buy this if possible) I have purchased the entire sensor kit : here for $44.95
These are smarted LEDs that can be controlled via program.
We will need to get some libraries in place, to start controlling NeoPixels via the Arduino micro-controller through our program .
A pack of 4 Flora RGB Smart NeoPixel version 2 is available for $7.95
 Alligator Clips
To test out circuit before we sew, it’s a good idea to have a set of alligator clips (price $3.95)
 Conductive Thread and Battery
 Needle $1.95
That’s pretty much what we need on the hardware side. Do get these things in place so that we can start designing and implementing our little DIY.
The Arduino programming language reference will be a useful guide to go through before we begin the coding exercise.
