Wireless Interface RF Modules Tutorial

[mvrk21mex]

i buy transmitter and receiver but receiver has to much garbage in data pin. when transmitter is off, garbage in data pin of receiver becomes worse. is this normal? im using hyperterminal to see received data text.

Are there smaller microcontrollers that could be used? Im trying to develop a keychain RF transmitter, and the microcontroller is just too big for the application.

Excuse me, is buying the pickit 2 necessary?

Are there any alternatives?

I was really excited to start this project until I saw the 80$ price tag... the most expensive component just for software...

@ObliviuxProductions You can buy cheaper alternatives, but I wouldn't recommend any of them unless you already know what you're doing. If you want to get started with micro-controllers, no matter which one you use you're going to need a programmer/debugger and it's a one-time cost.

Hmm , bummer. I didn't want to dwell into the MC topic until I had the finances.

Do you have any Tutorials that don't use microcontroller? Or do you know any good ones?

@ObliviuxProductions This might interest you: youtube.com/watch?v=alTPa7MLf9­o There's many ways it could be done better, but the project is a wireless starting point.

this is great, just what i have been looking for. My project is to design and build a wireless remote lighting control to turn on and off lights in the home. I was going to IR but now that i have seen this i am definitely going to use RF module. Thanks man!!!!! you save me a bunch hassle with research. Thanks

I work in an electronics store and I would like to build a generic RF Receiver to test general Garage Door Openers and Automotive remote entry/alarm Key Fob Remotes for my customers. Just as simple as this video. Push a button on the remote, and a LED lights on the board. Do you think something like that can be easily built?

hi, my name is umeed and i am trying to use the simplest wireless transmitter/reciever.. is the one u used the simplest one...

[pcbheaven]

Chris, if i may, should i suggest you talk in the videos?

[PyroElectroDotCom]

@pcbheaven Yeah, probably not a bad idea. I make these videos to supplement my project/tutorials and I know a lot of viewers have english as a second or third language. Text is just so much easier to understand. Either way, I suppose a human voice couldn't hurt!

[pcbheaven]

@PyroElectroDotCom text is ok, i use it sometimes myself for the video. If you have bad accent like i do, then text is a must. Speaking though is more important (IMO). I usually record the speaking, then i take the video and then i bled the video following the speaking. This recipe works for me. Some other times i just speak while i record, but the result is poor (bad accent, i make grammatical mistakes etctec)

I'll remember this when it's time to start playing with wireless communication, specifically for some thing like a wireless network, many random transmitters and a couple of recievers hooked up to a couple of computers. Take Care, We love it.
