Tutorial: Getting Started with the NRF24L01 | How to use | Arduino

[@darkphotons101]

Great tutorial, easy to follow, good explanation on the software side of things! p.s. at 1:53 you connected the NRF24 module to 5V instead of 3V3 during the fritzing demo.

Hi Darkphotons, thank you for the kind words. And yes you are right, it should be connected to 3.3V.

Do we need to solder capacitors to work?

[@xrphobby1341]

I used shift register 74HC165 to increase my push button switches, and 3 pins of Shift register (Load in Pin1, Clock in Pin2 and Serial out Pin9) are connected to arduino with wires and it's working ok. How is it possible to connect wirelessly 3 pins of Shift register to 3 or more arduino boards and achieve the same result with the use of NRF24L01? THANK YOU.

I'm using the module with antenna connector. I have problem using it NodeMCU as transmitter. Using it as receiver is fine. So I soldered 10UF capacitor to it. Now I can't upload sketch to NodeMCU while vcc&gnd wires still connected to NRF module. Serial port becomes unavailable. I have to remove vcc&gnd between them in order to upload the sketch. Please help.

Hi @Pal Sih, you might want to double check your soldering connection. When you solder the capacitor pins, it should only touch the respective pin. You might also suspect the capacitor, did you observe proper polarity?

[@jumbo999614]

@@TechToTinker Yes , I already checked polarity. vcc to positive of cap and gnd to negative of cap. I found this acoptex.com/wp/basics-project-083c-esp8266-esp-12e-module-and-nrf24l01-2-4ghz-rf-transceiver-module-dht11-sensor-readings-on-lcd1602-i2c-module/ The diagram for NodeMCU shows RSV(not sure if it is 5v output) to VCC of NRF24 adapter. I will desolder the capacitor and use this adapter instead. Do you think NodeMCU's rsv (next to SD3 pin) can output 5v?

[@TechToTinker]

@@jumbo999614 Im not familiar with ESP12 but according to that diagram, RSV stands for reserved pin. So you cant use it. Use VIN and GND pin instead. Or better use external power supply for NRF and connected both grounds (commonly ground).
