I wanted to kick off a thread and share some more information to help inspire anyone considering signing up and inform everyone who is selected as a Challenger.
This is just a starting point and everyone is very welcome to ask questions, either directed at Nicola (nwieland ) from Würth Elektronik or myself (JoRatcliffe ). Plus, everyone is free to use this space to share any additional resources they find useful or discoveries related to the kit.
The centrepiece of the kit is the Würth Elektronik ICLEDs (Integrated Controller Light Emitting Diodes).

|
: This is how the LEDs arrived - in reels like this - here at our office. |
|
: We will be dividing up the reels between all the Challengers. However, for convenience we will not be separating each LED individually. |
|
: Hope this made for a fun little insight into the behind-the-scenes of Design Challenges. |
Würth Elektronik’s RGB ICLEDs are advanced lighting solutions that are equipped with an integrated controller capable of PWM dimming. The inclusion of an integrated controller in each ICLED eliminates the need for complex circuitry and difficult PCB layouts. With a single microcontroller unit (MCU) transmitting information to the initial ICLED in a chain, subsequent ICLEDs receive the data through daisy-chain connections, simplifying the overall setup without requiring extra connections to the MCU.

The design challenge’s kit also includes an Arduino Zero (ABX00003). Würth Elektronik shared with me these design schematics for the Featherwing which I have uploaded to the Files section of this Design Challenge to help provide an initial technical insight into how the LEDs can be used.

The rest of the challenge's kit has not been forgotten but the key items above are mainly the ones that have been discussed so far in the challenge group. Files and documents shared here are correct as of 7th August 2025. This is intended as a ‘snapshot in time’ of the files and documents and will not be updated.
