Friends,
One site working with Picaxe controllers for wind mills, which are easily programmed via a BASIC-type language, is www.thebackshed.com. However, it is realized that a PLC has much more processing power than the Picaxe.
The beauty of the Picaxe is the ability to program the chip via a PC, so it does not need a separate burner. And there is no need to learn Assembler.
