Hi Arduino gurus,
I am looking a solution to connect Motor Shield driver, sitting on top of Arduino uno, and NRF24L01
I've connected 3.3v and ground to servo motor +ve and -ve.
Rest 6 pins, have no place, as shield is on top of Arduino UNO.
If there are any steps with diagram/video that shows - any soldering/breaking or any other easy way,..
Appreciate your response.
[ I had problems with L298N and nano, only one wheel backwards is not working, so shelved]
Do you mean the shield uses up the SPI pins for other purposes, or just doesn't bring them out, or what?
Best to give a link to the shield details.
please see the picture. The motor driver sits o top of UNO and takes all the pins. How can I supply to NRF24L01?
Here's the OP's pic:
It depends if the shield actually uses the SPI pins or not, but if not, you may be able to solder wires onto the little "pips" of solder on the appropriate pins.
Have a look at the shield's documentation or sample code to see if it uses the SPI pins: if it does I would imagine they are wired to the components on the board and can't be used for SPI.
You may find your shield here and see what pins are actually used.
I would in any case be inclined to ditch the motor shield which I think uses L293s and use a more modern, more efficient, driver module and choose one that's not a shield so you can use your own wiring scheme.
Or, but still dependant on the SPI pins not actually being used by the motor shield, you could use a screw shield like this. Put your motor shield on top, and take the SPI (if available) out the screw terminals.
