I don't know whether you remember but a couple of months ago we were discussing the merits of 433MHz modules. Have you tried these NRF24L04 modules?

I have had a few of them lying around for a couple of months and today I finally got around to setting up a small test with two of them. The reception far surpasses the 433 modules, with a reliable signal through 4 concrete walls. something I wasn't getting with the 433s.

The setup was made without the small stubby antenna, and I am suitably impressed. The only drawback that I have found is that the modules must be suitably orientated where signal attenuation is present.

Haha... I'll look into getting an Avatar... may even make my own in Blender 3D πŸ™‚

Yes, as a concept, I like the idea of checksum (and of course, a lot of code I have posted has no real error checking at all, as it's mostly to show the basics), and would certainly implement important checks in production code.

I have to run (just started a new job and need some shut eye), but I'll have a closer look tomorrow.

BTW... the code I posted with the 2 pots/servos can be increased by the array size to allow for 16 pots, which will take it to the 32 byte limit.

Cheers!
