Hi All,
I'm a beginner to arduino and my code is basically a mash-up from various tutorials.
It works perfectly (for me) but with one small issue.
Project Information: I am hacking an Air Swimmer Remote Air Swimmers - Awesome RC Flying Shark and Clownfish! - YouTube
control so that I can control it via web browser.
The code works how I need it to BUT there's one small issue.
After sending the first command every command after that repeats the previous one as well.
Here's my current code:
//ARDUINO 1.0+ ONLY

// if need to change the MAC address (Very Rare)
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

I know most of you are cringing for how poorly it is put together, but if there is a way so that I can get it to just run the command once without it repeating the previous one? I also attached the schematic if it helps. Just pretend the LEDs are the buttons on the remote.
Thanks a shit-tonne in advance.
