Build a compact multi-function IR remote system using Arduino Nano, a TSOP38238 IR receiver module, and an IR transmitter LED. This project combines IR signal decoding and IR signal transmission into a single embedded platform. The first Arduino setup captures infrared remote control signals and displays complete NEC protocol information including hexadecimal raw code, protocol type, address, and command values on the Serial Monitor. The second setup works as a programmable IR remote transmitter capable of controlling RGB LED strips and wireless motor functions using only three push buttons.

This project demonstrates real-world infrared communication by capturing, decoding, storing, and retransmitting IR signals for wireless control applications. Perfect for learning embedded systems, Arduino programming, EEPROM storage, and NEC protocol handling. 🔧

Triple Matrix Bonnet Makes Big Bright Displays 🔴🟢🔵✨

With our latest work on getting HUB75 RGB matrices working on the Raspberry Pi 5

we can now create stunning LED displays. But what if we want more pixels? At some point, we max out the bandwidth of the RP1 chip, but we can still squeeze out additional performance by updating the PIO commands to output two or three matrix strings instead of just one.

Thus, the Triple Output RGB Matrix Bonnet you see here! We're using the classic Active-3 pinout

with a switch to select whether the 4th or 8th pin is connected to address E.

New ability unlocked, vertical images !!! Though this seems like a trivial task (just rotate the camera) it is in fact not so straight forward. As the ai pipeline needs to be able to orientate the image correctly first before processing. This allows for the cleanest results. To this I've added a lis3dh accelerometer to detect the orientation of board when the image is taken. This is seen below labelled U11. For more updates on this project be sure to follow.
