sorry septillion, i thought i had used the tags, perhaps i need more practice ?
I do not wish to upset anyone, but has i have stated before, this Arduino is a hobby for me, yes i have a need to learn, but this is the only forum i have found that can give expert help. You mention wanting something for nothing or words to that effect, yes i could pay someone but who? i cannot find help locally, there are no college lessons in my local area so i have to self learn, this i am willing to do, but i am 70 years old, with 50 years working in Mechanical Engineering, sometimes things take time to sink in the old grey matter, no offence but give us beginners a bit of slack, or do not invite us to join your forums.
