A set of small but complete embedded programs — PIC instrumentation with LCD readout, and an NFC tag reader.
2025·PIC·mikroC·Arduino·PN532 NFC·HD44780 LCD·ADC·I2C
A collection of the smaller embedded programs that make up the everyday practice behind the larger builds — each one complete, compiled and doing a real job on real silicon.
PIC instrumentation (mikroC). A digital tachometer that reads three analog channels through the ADC and drives a 16×2 HD44780 LCD in 4-bit mode; and a motor-speed program that computes RPM and voltage and switches a transistor output while displaying the reading. Both carry their full toolchain output — compiled hex, listing and assembly.
NFC reader. An Arduino program driving a PN532 module over I2C to read passive MIFARE / ISO 14443A tag UIDs and report them over serial — the access-control front end from an internship task.
None of these is a headline project, but together they are the reason the headline projects work: the LCD, ADC, I2C and serial groundwork that a bigger robot quietly depends on.
