Ok.... I found this code and I set it up as they said. Now this happens ALL the time. I past it, and it has a load of errors. It beats me how it can work for some ells and not for me.
As you said Heroduino, writing it in code is a lot easier to understand. So please if can please fix the code for me.
Here are the errors and the code.
Error 1 Overload resolution failed because no accessible 'New' accepts this number of arguments. Servo_AP.vb 41 25 Servo test 12
Warning 2 Using DirectCast operator to cast a value-type to the same type is obsolete. Servo_AP.vb 41 44 Servo test 12
Error 3 The targeted platform does not support latebinding. Servo test 12Servo_AP.vb 43 13 Servo test 12
Error 4 'SetDutyCycle' is not a member of 'Microsoft.SPOT.Hardware.PWM'. Servo test 12Servo_AP.vb 66 13 Servo test 12
Error 5 'SetPulse' is not a member of 'Microsoft.SPOT.Hardware.PWM'. Servo_AP.vb 87 17 Servo test 12
