My name is Pooya Sanooei and I’m a web developer, designer, researcher, boxer, but above all, I am a man. A positive inquisitive man, just like you.
It all started at 8 a.m. when I had a call from a friend to build a simple handy wireless device. The idea was simple. Two devices talking by wireless range of 60 meter at least sending two different signals: right or left. The receiver device had 2 LEDs (each delegating right or left) that light up when the other one presses one of the push buttons.
I searched the web for 433Mhz antenna and found out I could use a simple 17.5cm wire. I installed and wired up my Arduino UNO for testing and connected 2 RFs to seprated UNOs to test it in action.
