For wearable electronics we like conductive

thread…it’s flexible and withstands hand washing.

Downside is that it doesn’t carry much current.

Here several strands of conductive thread have

been grouped to provide better capacity for the +

and – conductors down a pair of suspenders.

Driving 5V NeoPixels from 3.3V Microcontrollers

Increasingly, microcontrollers are running at 3.3 Volts instead of 5 Volts.That’s great news for

efficiency, but can present a communication problem with 5V NeoPixels. The 3.3V signal from the

microcontroller may not be “loud” enough to register with the higher-voltage device. The

manufacturer recommends a minimum signal voltage of 70% of the NeoPixel voltage.

There are two ways this can be addressed:

1. Lower the voltage to the NeoPixels so it’s closer (or equal) to that of the microcontroller. This

is why we recommend LiPo batteries for FLORA projects: 3.7V is enough to run a short length

of pixels, and the microcontroller is comfortable at that voltage as well.

2. Use a logic level shifter (http://adafru.it/e5g) to step up the signal from the microcontroller to

the first pixel.
