The first thing you need to do is connect NeoPixels smart color LEDs to your QT Py. NeoPixels come in many form factors but connecting them is basically the same. There are three pins: ground, 5v power and data. You'll connect these to the appropriate pins on your QT Py.
For an in depth look at NeoPixels, check out this guide.
There are options for connecting NeoPixels to the QT Py. You can solder headers to your QT Py and use a breadboard, or you can solder wires directly to your QT Py. It's up to you!
To demonstrate the examples in this guide, I have connected a NeoPixel LED Strip with 3-pin JST Connector to the QT Py on a tiny breadboard using Silicone Covered Male-Male Jumper Wires. You can use any form of NeoPixels and connect them however you like, but if you want the examples to run without modification, ensure that you've connected them to the pin listed below.
- QT Py A3 to NeoPixel data / DIN (data in)
- QT Py GND to NeoPixel ground
- QT Py 5V to NeoPixel power (5V)
Once you've got everything connected, it's time to get coding and light it up!
