Concept
Packet radio at 2.4 GHz with ack/retry.
A little theory
GFSK, 250 kbps–2 Mbps, 125 channels. ShockBurst FIFOs. In the classroom, treat nRF24L01+ 2.4 GHz Radio (with adapter) as a advanced part using SPI. Typical India street price is about ₹70–₹180. 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.
How it works in a project
RF24 library, matching pipes/addresses on both ends. 3.3 V module — use the 8-pin adapter with AMS1117.
