Hey guys! Sorry for the really late reply. Unfortunately, I'm having problems with CW2's code. The LED on the Ping Ultrasonic Sensor just stays green, and after placing a few breakpoints, it never reaches the interrupt function. I think you need to send 'true' or 'on' to the Ping for 5 microseconds before reading values from it. But I can't find any way to delay in microseconds. Thanks for your help again if possible!

I did a few tests today. For some reason the relay works if I power it with 3.3v instead of 5v. So it's all good now. Thanks for the help guys!

Have you tested it just with a volt meter with nothing connected?

Thanks for the suggestion, but other components don't seem to be the problem.

I isolated the Netduino from everything and tested it with a volt meter. Everything looks perfect. Identical to the Arduino (Apart from the Arduino giving out 4.97v, while the Netduino only gave 3.3v). However, when I tried my relay module on both the Arduino and Netduino (both isolated from everything), it worked 100% on the Arduino, but still not the Netduino. This ain't making sense at all... I have to wait 'til the morning to get some LEDs. I can't seem to find one anywhere.

A picture could be very helpful.

I think I'll record a video when I pick up that LED tomorrow. Not exactly sure what to take a photo of now I think about it.

Thanks again for the help! Really appreciate it.

Are you using an external power supply? If so, are you sure all the gounds are connected?

I've tried it with both an external 12v supply, and just the USB cable. Neither work. I can upload a picture if you'd like.

The following code can be used to measure pulse width.

Thanks so much for that CW2! Really appreciate the code.
