Assorted Microcontroller Sketches

CardKB Text Buffer

Modified version of the M5Stack CardKB text buffer library refactored into a single page sketch that works with the adafruit 1306 OLED screen library. The adafruit library does not return the cursor postion so an average character size in pixels was used.

Clock

Arduino Uno based alarm clock.

Charlieplexed Larson Scanner

Code from one of my earliest electronics projects.

LED Matrix

Code for the strange LED Matricies I bought long ago.

ESP 8266 WiFI Scanner

Simple ESP8266 project to scan for nearby WiFi networks.
