The dust is settling after all of the fun I had with the ESP8266 project. It’s time to move onto something else I’m new to. Remember those RF transmitter and receiver pairs I got a little while ago? I’ve been thinking up ideas on what to use them for, and I think I’m settled on one idea.
I set up the receiver with an LCD to display messages while I play around the RF pairs. My AMS1117 and ATmega328p boards came to the rescue once again. I only have one Arduino Uno, and a Mega that’s still attached to the Light Show. I haven’t jumped on the Arduino Nano wagon yet since I have my own boards. On the transmitter side, I set up four push buttons to select one of four commands to send to the receiver. Here is the transmitter setup, which was moved over to AMS1117 and ATmega328p boards after taking these pictures. In this picture, I’m pressing the second button… … which sends the string “down” to the receiver.
Figured it out?
A remote controlled robot!
Since I’m using ATmega328p’s for both the transmitter and receiver, I have plenty of pins to work with. I don’t want to set anything in stone just yet, but you can bet that LCD will be part of it (even though it’s not the color I wanted… lousy eBay seller’s idea of blue). I need to work on some actual written plans before I start constructing anything so stay tuned for when that happens.
Thanks for reading!
