Blue Led Grove

The Blue Led Grove module is a Seeed Grove-system board with a blue LED, ready to plug into a Grove Base Shield or any Grove port with a single cable. There is no breadboard wiring and no resistor to choose: connect it, set the pin HIGH, and the LED lights up. It is a simple, reliable way to add a blue status light to Arduino projects and a good first module for beginners.

Blue Led Grove Specifications

What's in the Box

• 1 × Grove blue LED module

Tip: Plug it into a digital Grove port such as D2 to D8 on the Base Shield and start with the Blink example, changing the pin number to match. Use a PWM-capable pin such as D3, D5 or D6 if you want to fade the LED.
