Hi everyone.
Just wanted to say thanks so much for your help. I am doing this project to help my brother (a farmer in South Africa) solve a problem with planting seeds. Its a bit time critical because the planting season starts from September and I was stuck for days with doing the serial comms coding.
The first Nano monitors 8 x IR sensor to detect the seeds dropping down a tube into the soil. It then communicates the status to the 2nd Nano in the cab of the tracktor. It works well on the bench and I should know in a few weeks how it works in real life
Thanks for the help.
Regards
Norman
