Last time I gave a talk about the Internet of Things I wished I had a device to demonstrate to the audience what I was talking about.
I took a Particle Internet Button, which consists a ring of color LEDs, 4 buttons, an accelerometer and a buzzer, added a cellular Particle Electron and hooked it up to Twilio so you could text the name of a Crayola color name to see the ring change colors.
Hardware SurgeryThe first challenge was that the Internet Button is designed for the Particle Photon which is shorter than the Electron. I had to modify both the Electron and the Internet Button to put them together.
I desoldered the 12 back pins on the Electron (B0 to B5, C0 to C5). I also had to move the Internet Button LED 6 to position 12 to make room for the SIM card holder on the Electron.
Electron with 12 missing legs to fit in the button
At this point the Electron fit, but the LED didn't light up because they had no power. I had to put a diode in between the lithium battery pin on the Electron and the LED power trace (VIN). The diode is there to prevent short circuiting the USB power to the lithium battery if both are plugged at the same time.
Diode connecting the lithium battery to the LED power
The information flows like this:
SMS -> Twilio -> Webhook running on hook.io -> Particle Electron
The Webhook is a Javascript program that converts the Crayola color names likes Razzle Dazzle Rose and Atomic Tangerine to red, green, blue and publishes a light_demo/color event to the Particle cloud.
The Electron subscribes to the light_demo/color event and animates the ring of LEDs.
Start by creating an account at hook.io to be able to quickly write Javascript code that will run when a URL is accessed. My hook.io username is monkbroc and I created the webhook light_demo so my webhook URL is https://hook.io/monkbroc/light_demo
The Javascript code that will receive the SMS from Twilio, translate the color and publish the event to the Particle cloud is attached at the end.
Next create a free account at Twilio and add a phone number with SMS capabilities. Tell Twilio to forward incoming SMS to the webhook above (https://hook.io/monkbroc/light_demo).
Finally, program the Electron with the Internet Button library and the code to subscribe to the color change event. The code for the Electron is attached at the end.
The firmware waits for an event, then turns off the LEDs one by one, then turns them back on with the new color.
The Internet Button a great device to get your creativity going when you're in WiFi range and now with an Electron I can take it anywhere!
Incoming SMS webhook

function authenticMessage(params) {
return params.AccountSid === hook.env.TWILIO_ACCOUNTID;

//----------------- LED Handling ------------------------//
/*-------------------------------------------------------------------------
Spark Core library to control WS2811/WS2812 based RGB
LED devices such as Adafruit NeoPixel strips.
Currently handles 800 KHz and 400kHz bitstream on Spark Core,
WS2812, WS2812B and WS2811.
Also supports Radio Shack Tri-Color Strip with TM1803 controller
400kHz bitstream.
