Is there a way to do this without soldering?
The RGB LED breakout boards like the ones shown above would require soldering, but you might find ones with wires already attached.
- There are 8 LEDs (100, 100, 50, 40, 30, 20, 10, and gutter) so there would only be about 32(?) solder connections if you daisy-chain the 5v, ground, and data lines using euro-style terminals.
-- One data line connection to the Pro Micro
-- Four connections to each LED 5v, ground, data in, and data out.
Put a 5-6 position terminal strip next to each LED.
- 5v terminal has 5v in, 5v out, 5v to RGB LED, 5v to IR LED. (and 5v to sensor red wire
if you're using an IPac)
- Ground terminal has ground in, ground out, ground to RGB LED, ground to IR LED, and ground to sensor.
- Data in terminal has LED data in wire and data out terminal from previous LED. (or Pro Micro for the first LED)
- Data out terminal has LED data out wire and data in terminal for next LED. (or nothing for the last LED)
- Sensor data terminal has white wire from sensor and wire back to either GPIO or IPac.
- 3.3v terminal has 3.3v in, 3.3v out, and 3.3v to sensor red wire
if you're using GPIO.
The rest of the connections you can do with euro-style terminal strips (IPac)
or euro-style terminal strips and Dupont jumpers. (GPIO)
This pic is an example of using euro-style terminals with daisy-chained 5v, daisy-chained ground, a single LED and current-limiting resistor.
