Ultrasimple LED module

Postby albertinjo » Thu Jun 26, 2014 11:58 am

In gamebuino trailer I saw a module that had 2 flashing white leds on it. I suppose it is just 2 LEDs tied to A4 and A5 pins of arduino used as digital outputs to flash LEDs???

Yeah, just 2 leds and 2 resistors soldered on a small piece of proto board. I used it to see when something is happening on the I2C bus.
