I finally wrapped up my wireless LED controller box. There’s an Uno at the bottom with an Xbee shield. The two buttons are for navigation of animations presets on the receiver. The 7 segment gives visual feedback of mode number on receiver. A single NEOPIXEL on the left is for power and battery life feedback, thus being the smallest Fast LED project , for me, to date! The enclosure is from Adafruit, and is this small version of the box, hindsight reveals I should have ordered the larger one.
Well done. Very clean. Just curious, what are your doing with your Xbee shield?
i am planning on making similar LED controllers for 3 robot-style costumes where any 1 of the controllers can be a master and the other 2 slaves so all animations are sync’d. I looked into 433MHz RF communication or possibly bluetooth but never considered Xbee.
@Dave_Morris The xbee is very easy (for me) to configure and use. I have tried other wireless chips/boards, but I like using the Xbee. Just hook it up to a Serial RX TX, and poof you’re sending data.
The code for the Xbee’s is small too:
if (Serial.available()) {
incomingByte = Serial.read(); }
I send a small, single byte over the air to control the receiver’s animation code via switch case statement.
what kinda range do you get with those modules? (If you’ve tested)
These are Series 2 bee’s. https://www.sparkfun.com/pages/xbee_guide
