I want to build this project. But I don't need to power it by batteries. Has anyone the circuit diagram (in FrizIng?)
I have also the problem, that I can't see, on the breadboard picture of this project where the red wire from the battery ends after the connection to the Arduino?
Does it go to the FET and the R7?
Can anyone help me?
