#67238 I agree with schufti. I don't see any capacitors in your schematic. They are a basic requirement. What also is important is how components are connected together. A lot of people think that as long as there is an electrical connection between two points then it is OK. Long jumper wires are not the same as short current paths.

When someone has problems like you are experiencing I ask for a photo of what you have connected. A schematic is useful but it doesn't show how things were done. A photo will often speed up the process in finding solutions.
