See my post about "A Hardware Guy Drowning In A Software World". You will find the design files for this. I called it the Collision detector. The components would work for you. Thanks Bill, I'll have a look. I'm a software guy lost in hardware.

Hello Abdalla and, Welcome to the forum (As Stefan said).
I use IR remote emitters and sensors in my - yet to be sucessful - autonomous bot. The receiver I use is a generic 38khz device and an Osram emitter LED at 980nm (i think) (watch for the IR frequency, the nm or wavelength of the emitter & receiver).
Do you want to use a TV remote? Make your own remote? It's all possible.
The most common frequency of "modulation" is 38khz. Get an InfraRed receiver LED or transistor which has a relatively wide bandwidth (800nm to 990nm),connect it up to a scope and fire away at it with your TV remote.
If any of this confuses you just post back and I will (or the community will) respond.
Great question. This is a wonderful lead-in to specification sheets.

Good luck!
Regards.

This is a great post as I'm trying to do something similar. I don't have a scope but will a multimeter work?

I set my meter to hz and what i got from the reciever was .028 k hz when i hit a button the remote. so I guess the meter is not good for measuring this?

Yes. You can set the period and duration (within a period) of the pulses, or alternatively the frequency and duty cycle.

namespace Microsoft.SPOT.Hardware
{
    public class PWM : IDisposable
    {
        public PWM(Cpu.PWMChannel channel, uint period_us, uint duration_us, bool invert);
        public PWM(Cpu.PWMChannel channel, double frequency_Hz, double dutyCycle, bool invert);

        public uint Duration { get; set; }
        public uint Period { get; set; }

        public double DutyCycle { get; set; }
        public double Frequency { get; set; }

        ...
    }
}

Frequency and DutyCycle are only syntactic sugar, they are internally converted to Duration and Period. The latter are both interpreted as microseconds (in the source code, the comments erroneously claim that they are a frequency and a percentage).

Best regards

This is awesome!!! exactly what i've been looking to do

Yep

I believe so, but no details are available so far.

The makers of Netduino are working hard on the Netduino 4.2 RC3 firmware. Stay tuned!

Thanks... waiting patiently

just getting started with netduino and this looked like a cool project. What was hoping to do is detect any remote controls codes and be able to send them codes thru code. I've run this but my remote (Comcast remote) just reports.. Code=0x00000000 This will come up for every button push anywhere from 2 to 8 times. Any help would be appreciated.
