With regards to powering the remotes, has anyone ever notice that the pins on a cr2032 coin battery holder fit straight into the VIN and GND pins of a Nano, works a charm you just have to cut a small piece of the plastic away from the battery holder to allow for the reset button. I used a dremel for this, but was the only mod I had to do , the battery holder is almost designed for it otherwise. Not sure how long it will last though, depends what you load its up with as always.
thanks for the link, I'm on my way to have a look.
Thanks for the speedy response mate, its good to be on board with the my sensors crew, certainly helps to have like minded IOT tinkerers to bounce off.
Good to know its possible with a pro mini too, very encouraging. I have a couple of standard tft screens available to try out, one is a 1.8" V1.0 SPI 128*160, it has a single row of pins down one side, blue pcb and takes a normal size sd card also.Pins are labeled on the screen, how did you go about hooking it up to the pro mini?
The other is a red board 2.4" TFT LCD Shield for an uno, again, not sure how to go about connecting to the pro.
Any advice mate?
Also, Did you have to do much with the code, other than the pin assignments?
I was actually starting to doubt whether it was possible to run nrf24lo1 as well as a display also with SPI, side by side on the smaller arduinos.

Hi Everyone, seems Im late to the party. Only just stumbled upon this site tonight as Ive been struggling to get a mention display to work as a remote transmitter from one arduino nano and a NRF24L01 radio with a nextion basic 2.4" display, to another arduino either nano or uno clone board-nrf24l01 radio, and a l298 motor shield.
It seems what you guys have been doing is very similar, only with standard tft panel and not nextion.
Has anyone had any success with boards other than a mega? Im trying to keep the "remote control" part of the project as small as possible, even use a pro mini if I can...
Looking forward to any sort of advice/code you can offer...?
Thanks
