If C/C++ is more your preference, the RP2040 MCU can also be programmed using the Arduino IDE.įor more details on beautiful RGB lights, we’ve previously presented Everything You Might Have Missed About Addressable LEDs, and for more details on why they can be so fun to wear, check out our Hackaday Badgelife Documentary. has published the KiCad files for the badge, and the CircuitPython firmware is shared with the project. The PCB also features two capacitive touch pads. Finally, the LED coordinates were pasted into the KiCad PCB design file.Īn RP2040 microcontroller controls the show, and a switch on the badge selects power between USB and three AA batteries and a DC/DC boost converter. A little more math translates the points “off origin” into the center of the PCB space and scale them out to keep the first two 5 mm LEDs from overlapping. To position each of the 64 addressable LEDs within the PCB layout, computed the polar (r,θ) coordinates in a spreadsheet according to the Vogel model and then converted them to rectangular (x,y) coordinates. has developed a Fibonacci Spiral LED Badge to bring this natural phenomenon to your electronics. Fibonacci numbers are seen in the natural structures of various plants, such as the florets in sunflower heads, areoles on cacti stems, and scales in pine cones. ![]()
