Concept
Chirp spread spectrum: slow bits, kilometres of range, tiny power.
A little theory
LoRa modulation, 433 MHz ISM in India (comply with WPC power limits). In the classroom, treat SX1278 LoRa 433 MHz Module as a advanced part using SPI. Typical India street price is about ₹180–₹350. 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.
