Story

Step 1

With Adafruit (not Arduino) Gemma I start my first step into wearable clothing. I ordered the Adafruit Gemma Sequin starter set and would like to let you participate in the Unboxing here.

Adafruit Gemma Sequin starter set

In the Starter Set the Gemma v2 is delivered: this has an on/off switch on board. In sum, it is a tiny device, which should be removed before a wash. The sequins are different: tiny, bright LEDs, which should also hold a washing machine, Adafruit says.

dry test: lightning up without gemma

I tested first, if the LEDs also work without Gemma: the construction shows a power supply on a Breadboard, which supplies a white LED with voltage. Left hand in the image of Gemma with green status LED.

Sequin LED shines in front of a notepad

Pretty bright the tiny - in front of a red notepad.

Step 2

The next step is to teach Windows the drivers: following the Adafruit instructions, this works quite well. However, already 2 hours have to be planned for detailed reading and implementation. We do not want to risk anything and send the Gemma immediately to the electronic sky.

This includes the offline IDE from Arduino, since the online IDE does not have the device to choose from.

Schematics

The schemata can be seen quite well here: on each sequin, + and - is printed.

Interesting I find the attached, conductive thread and needles, so I now intend to equip my woman's handbag with light: when opening the zipper or the Velcro there is then light.

Step 3

Oh still something: no output is supported on the serial monitor. So carefully deal with the code and passed through before! Before the code can be flashed, it is to be put into the firmware update mode: please press the button lightly on the Gemma and flashen during the red flashing.

the white Sequin LED is on (top), the red internal LED blinks also and we have a green status LED onboard

Update 04.07.2017: first test with crocodile clip and thin conductive thread

1 / 2 • Sequin LED connected with crocodile clips powered by a battery pack (1/2)

You will find more under my account.

introduction example "Blink" an Sequel with Gemma

/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.
 
  This example code is in the public domain.

  To upload to your Gemma:
  1) Select the proper board from the Tools->Board Menu (Arduino Gemma if
     teal, Adafruit Gemma if black)
  2) Select the uploader from the Tools->Programmer ("Arduino Gemma" if teal, 
   "USBtinyISP" if black Gemma)
  3) Plug in the Gemma into USB, make sure you see the green LED lit
  4) For windows, make sure you install the right Gemma drivers
  5) Press the button on the Gemma/Trinket - verify you see
     the red LED pulse. This means it is ready to receive data
  6) Click the upload button above within 10 seconds
*/
 
int led = 1; // blink 'digital' pin 1 - AKA the built in red LED
int seq = 2;

// the setup routine runs once when you press reset:
void setup() {
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);
  pinMode(seq, OUTPUT);

}

// the loop routine runs over and over again forever:
void loop() {
    digitalWrite(led, HIGH); 
    digitalWrite(seq, HIGH);
    delay(3000);
    digitalWrite(led, LOW);
    digitalWrite(seq, LOW);
    delay(3000);
}
