Have fun with this tiny RGB LED module by cool effects of flashing, rainbow, even letters, pictures or animations. This requires little changes for existing programs to shift from RGB LED strip to RGB LED module string. Supports arduino uno & mini pro digitalWrite function and only PWM pins. The module adopts the same high-brightness RGB LED in the traditional RGB LED strip, inheriting its excellent display performance and is fully compatible with the driving circuit or program. RGBLED Signal Input/Output A library that manage 4 legs rgb leds colour and light duration. Please check my video to get more information and to se how RGB module work: I prepered three simple examples to work with For this example you will need: Arduino board RGB module Pushbutton breadboard potentiometer (variable resistor. This also makes it much simpler and more flexible to configure the length of an RGB LED strip, without the need of cutting a RGB LED strip or soldering every LED pieces. This is small tutorial how to use R G B module with Arduino. And such feature makes it possible to cascade more than 100 modules with a total length up to several tens of meters but power requirement no more than 5V 2A. Thanks to such individual module design, RGB LED strip built by such independent modules can realize extremely low power consumption per meter compared to traditional RGB LED strip. Compared to the traditional RGB LED module, where three control signal pins are required for a single LED, this module only needs one signal pin for all LEDs in cascade. The Gravity interface provides a more elegant manner for the connections between modules and most of mainstream controllers such as Arduino, micro:bit, Firebeetle Series, LattePanda, and Raspberry Pi with an abundant kinds of DFRobot IO expansion shield. This 2-wire transmission can be used to cascade additional Grove - Chainable RGB LED modules. It communicates with a MCU using 2-wire transmission (Data and Clock). It provides 3 constant-current drivers as well as modulated output of 256 shades of gray. In the second for loop we invert the whole logic and the color of the LED goes back from red to green.Gravity: Digital RGB LED Module is a cascadable single RGB LED module compatible with RGB LED strip. Grove - Chainable RGB LED is based on P9813 chip which is a full-color LED driver.
