IoT Transit LED Display (2026)
- Adafruit Matrix Portal S3 drives dual 64×32 RGB LED panels over HUB75, wired into the first panel's input.
System scalability
IDC ribbon daisy-chains the first panel's output to the second's input, merging two 64×32 panels into one 128×32 addressable display.Firmware
CircuitPython with Adafruit's Protomatter library drives the chained panels as a single display; required over Arduino, which lacks chainable HUB75 support.Power management
Split-rail design: a 5V 10A switching supply feeds both panels through a SparkFun screw-terminal adapter, while the Matrix Portal S3 runs independently over USB-C, isolating logic and display power domains.Software logic
Custom scrolling text, fonts, and color-coded destination alerts with per-location timers, built on Adafruit's Animated Message Board framework.

Arduino Logic Gate Shield (2025)
Logic integration
on-board AND, OR, NAND, and NOR gates implemented using 74-series logic ICs, covering core combinational logic building blocks.Component assembly
precision SMD soldering for ICs, transistors, and resistor networks.Power & signal routing
level-shifting and regulation traces between Arduino Uno R3's 5V logic and 3.3V on-board ICs, maintaining clean signal integrity across the voltage domain boundary.Hardware validation
end-to-end validation of truth tables and gate-level logic correctness via multimeter continuity testing across all input combinations for AND, OR, NAND, and NOR expressions.
