trying to make Microcontrolled timer with a screen that is able to read nfc commands. The idea is to read nfc tags to ad or subtract time from the timer.
What components would i need to make this. What coding necessary and how affordable would this project be(im looking to make multiple relaible and not too expensive)
You can choose an ESP32 or Arduino Nano 33 IoT. Both have built-in Wi-Fi (useful if you want to integrate remote features in the future) and are relatively affordable. For NFC, PN532 NFC Module is a popular, reliable NFC module that’s compatible with ESP32 and Arduino. It can read NFC tags and send their data to the microcontroller.
