Uni-colour Light Emitting Diode (LED)

These high-brightness 3mm or 5mm diameter LEDs in clear packages have a built-in current-limiting resistor so that they can be powered from a 5V DC supply, consuming around 15mA.

You can connect them directly to your Arduino/Genuino Uno or Mega, or a breadboard, without soldering using the pins attached to the leads, and then control them from MECControl.


The red lead may be connected to any of the digital pins on your Arduino/Genuino Uno or Mega, labelled 2-13 on the Uno and 2-53 on the Mega. However, if you wish to control the brightness of your LED, it must be connected to digital pins 3, 5, 6, 9, 10 or 11 on the Uno or digital pins 2-13 or 44-46 on the Mega.

The black lead should be connected to ground (a voltage of 0V).

Diameter, lead length and colour options

3mm or 5mm diameter LED packages are available, with lead lengths of approximately 50cm, 1m or 1.5m.

Colours available are red, green, yellow/orange, blue and white. Since the LED package is clear, the colour of the LED is indicated by the coloured tag around the leads.

Please contact me if you would like a custom length, voltage or design.

Available in 2 diameters, 3 lead lengths and 5 colours
