Does anyone have experience with the dfrobot TCS3200 color sensor?
I cannot seem to get the LEDs to light up
Hi @Peter47774,
The schematic for that part looks like this
So you’ll need:
- 5V connected to VCC
- GND connected to GND
- 5V connected to LED
You could use a digital IO for LED instead, but you can test with a 5V signal to isolate code from the situation.
Let me know how you get on with it!
Thanks Graham. I worked out by trial and error that the LED needed input voltage so I am using the Arduino 3.3 V to supply this
The documentation did not show that the LED needed to be connected

Neat, I’m glad it all worked out!
By all means, drop back and share what you’ve made
