Arduino Lab
Microcontroller solutions and automated control systems for modern radio equipment.
Arduino UNO-nano DDS VFO
A Variable Frequency Oscillator (VFO) built with Arduino UNO and a DDS (Direct Digital Synthesis) module. Used for precise frequency generation in radio experiments and transceiver control.
Band Decoder & Antenna Switcher
An automated band decoder that reads the current operating frequency and switches antennas accordingly. Eliminates manual antenna selection during band changes in contest operation.
Morse Code Keyer — nanoKeyer
An Arduino Nano-based electronic keyer with adjustable speed, memory, and sidetone. Compact enough to fit in a small enclosure for field use.
