Controlling 6 PWM while having NFR24 radio module wired

Projects General Guidance

Hey !

So I want to both have :

  • the NFR24L01 wired to the arduino Nano (pins D7,D8,D11,D12,D13).
  • and controlling 2 RGB 9W LED via 6 transistors via the same Nano.

The only way to make the LED light intensity to vary via the transistor is with a PWM pins right (and analogWrite) ? I have D3, D5, D6, D9 and D10 available, so only 5 transistors can be wired this way.

BUT the last PWM pin D11 is used by the MOSI pin of the NRF24, and apparently there's no way to change that. Too bad there's only 6 PWM pins on the Nano...

Am I stuck ? Is there another way to resolve that wiring limitation issue ?

Thanks for your help !

Search for Arduino library for software SPI.

I don't really get it, how SPI is going to solve my problem ?

Thank you :slight_smile:

Software SPI can use any digital pins.

Is there another way to resolve that wiring limitation issue ?

Use a different Arduino.

So I could use that library (plus digitalIO apparently) to wire the NFR24 on any digital pin right ?

Yes.
