Gyro’clock parts arrived!

Yesterday I received the Gyro’clock parts I ordered from Adafruit. And here is the set that will be used on the first prototype

The first thing I did was to test the Neopixel stick with the ATTINY since it is the most interesting part of the bunch. I soldered four jumper wires to the terminals of the stick so I can stick it onto my breadboard. As added protection, I used a 470 Ω resistor between the data input pin and the ATTINY data out pin.

All LEDs in the Neopixel array can be individually addressed using a single data pin.

The Neopixel can be powered from 4-7V. So I used +5 V for both the ATTINY and the Neopixel. To test it, I generated an interrupt signal by momentarily tying the interrupt pin to +5 V. The Neopixel stick flashed as expected when an interrupt is created.  Of course I didn’t see the time displayed yet since I wasn’t actually spinning the device, but this confirms that the Neopixel stick can be controlled with the ATTINY.

After successfully testing out the Neopixel stick, my next step is to test the L3GD20H gyroscope. Once I am able to read data from the Gyroscope, I am ready to put the hardware together, which I think will be the hardest part.

One step at a time I am getting there, and this is exciting!
