PWM with the K8055/61 and an LMD18200 H-Bridge
The hardest part of this project was getting hold of a LMD18200
H-Bridge chip. I had to buy it in Hongkong and it took ages to finally
get here. The LMD18200 has a peculiar pin-out and does not use a 0.1
inch distance between pins. Hence it won't directly fit onto a vero
board or a standard bread-board.
The actual circuit diagram is fairly straight forward and follows
the recommendation in the data sheet for the chip. Be aware that the
LMD18200 does not function at voltages below 12V.
