Receiver for a KeyFOB - best controller?

Wireless & IoT

I got interested in working with the Arduino platform a little over 2 years ago. I’ve had a BLAST making all sorts of amazing things with it, mostly halloween props that are controlled with my iPad.

So, I have a zombie on the roof of my car. No, really.

Anyway - there’s a button inside my car that causes it to move - it jerks it’s legs about.

What I want is to have a button on my keychain to activate it when I’m not in the car.

So I need to hook up a microcontroller to a relay that controls it.

But since I started working with the Arduino, so many new options have popped up. Xbee… Raspberry Pi… and truth is, I know NOTHING about those platforms. But I LOVE to learn new things.

So, what I need is a microcontroller that can operate a relay, send serial commands (I’ll be using a mp3 breakout board to have it make sounds as well, I have a few I bought for halloween props. They are controlled via serial commands), have a low current draw so it doesnt kill my car battery, and interface somehow with some RF receiver that will accept input from a KeyFob. I know I can do this with an Arduino. I googled a bit and I know I can get the parts.

But would a newer/alternative platform be better for this application? I truly know next to nothing about these other platforms, what they are best suited for etc…

So knowing what I just posted, what would you use and why?

Sounds like you have the same requirements as in this thread:

Um - not at all… I’m not doing anything with OOK/ASK TX and RX and any of that. At all. I can easily build what I’m talking about with an Arduino. I was asking if there were a BETTER option…

Read through that thread. What is wanted in this other thread is a hand held transmitter that turn something On and Off.

This is exactly what you want to do and that thread has suggestions.

Your requirement is too simple to require another processor just to turn a relay on/off.

I dobt need a remote button to work a relay. I need one to randomly program the duration of the relay, and send and receive serial commands.

Again- I KNOW how to do this with an arduino. I’m not asking HOW to do it. I’m asking if another micro controller other than an Arduino is the best option.
