Concept
TFT LCD with ILI9341 controller over SPI, optional resistive touch.
A little theory
Needs enough RAM/flash — ESP32/Mega happier than UNO. 3.3 V logic often. In the classroom, treat 2.8" TFT 240×320 ILI9341 (SPI) as a advanced part using SPI + optional touch. Typical India street price is about ₹400–₹900. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
