Thanks Andy.

I think I understand what you are saying,

I am open to use any control system that is recommended to me, the reason I initially chose Arduino is that I am familiar with Arduino IDE writing, also I have several Arduino Uno's in my collection of spares, I can afford another £20.00 if it's worthwhile.

Did you read my schematic right, the drawing shows the SSR input as vdc, the output shows vac.

You seem to know what I am trying to achieve, as stated earlier, I am a Mechanic not an Electrician, can you guide me by supplying a schematic??

Regards.
