 Bigger Bigger  Smaller Smaller  Reset Reset

Hi I've made some neato LED gloves with my arduino. In my next build, I plan on using 1 Pro Mini per glove instead of 1 duemilanove controlling all 10 LEDs. The thing is, now I can't have patterns for all 10 LEDs. I was thinking I could have the button I use to change modes in 1 glove and send a signal to the other arduino when the button is pushed. I just need simple 1 way send/receive capabilities but I'm not sure what to look for hardware wise, thanks for your help smiley-grin

Also, this is a video of my project (I wasn't allowed to post it in my first post since it was my first post ever)

Why not wire the same button to both arduinos? No need to send messages then.

I don't want any wires going between the gloves that will get in the way. In my second build, I want each glove to be separate so they are easy to put on and take off and so no wires get in your way when you use them

You've ruled out using wires between the Arduinos, so, your only remaining choice is wireless. There are a number of RF modules that can be used to send or receive data.

Which one to use depends on availability, price, range, and your skills as a programmer and a googler.

Sorry, I mean to include in my original post that I was looking for wireless solutions. I'm looking for something really really small scale that will only take a couple output pins and is relatively cheap. I just need to send the button push which could be represented extremely simply, so I don't need some complicated blue tooth device or anything. I'm pretty unfamiliar with what hardware I'de be looking for though as I'm really new at all of this

Google "Arduino RF". Lots of inexpensive choices. Since the communication between the Arduino and the RF sender or receiver is via the serial port, they don't require more than 2 pins for a software serial port.
