Laser transmitter module for Arduino and other microcontroller projects
This module has a 650nm Red laser diode head with resistor. It will produce a focused red dot. Please use with caution and never look directly into the laser or point it into someone else's eyes.
RGB full colour 5MM LED module for Arduino and other microcontroller projects
This module has a 5MM RGB LED that can be used to create virtually any colour by varying the intensity of the 3 colours by using the PWM output to each pin. Resistors will be needed to connect to an Arduino.
WS2812B SMD High Brightness Individually Addressable RGB LED
The WS2812B is a smart RGB (Red, Green, Blue) LED module that is capable of displaying up to 16,777,216 colours at 256 different levels of brightness per LED. Each LED can be controlled individually using a microcontroller (e.g. Arduino, NodeMCU).
