We’re going to start with a Common Cathode circuit + code because it’s more intuitive (and similar to our red LED tutorials) before covering the Common Anode. Notice how the RGB LED type is clearly labeled. Here are two screenshots of supplier websites (Sparkfun and Adafruit). Where this ADC reads the voltage which is in analog form across potentiometer and depending on the voltage obtained, the PWM signals duty signal can be adjusted using Arduino Uno where RGB LED intensity can be controlled using D9 D10 D11 pins of Arduino Uno. A clear Common Cathode RGB LED from Sparkfun. In addition, the LED requires an EL2596 for each of its colors. With rgb color controller for you choose from, you can adjust the brightness of your choice through ir remote, and the speed and light effect is very convenient. The 3 potentiometers are shorted with, the pin A0, pin A1, and pin A2 of the ADC channel of Arduino Uno. Only Common Anode LEDs can be controlled with the EL2596. RST Pin: used for resetting the microcontroller when required.Whether youre looking for a p6 rgb led module or led rgb smd, weve got you covered with a variety of styles. AREF Pin: analog reference pin is the voltage reference pin Check out these gorgeous rgb led common cathode at DHgate Canada online stores, and buy rgb led common cathode at ridiculously affordable prices.TWI Pins: A4 and A5, helps in communication.Connect the 3 cathode legs to 220 Ohm resistor and diode as shown in the circuit diagram. Then, how do you use a common anode RGB LED Connect the Common Anode of the RGB LED to Digital Pin - 8 on the Arduino UNO.

LED pin: pin13, LED glows when this pin goes high Common cathode means that the cathodes of all of the LEDs are common and connected to a single pin.

PWM Pins: The PWM pins are 3,5,6,9,10 and 11 which gives an 8bit output.

External Interrupt Pins: Pin 2 and Pin3 are external interrupt pins that are activated when the clock goes high or low.

Serial Pins: TX 1 and RX 0 pins used for communication for transferring and receiving of data between peripherals.Memory: ATmega 328 microcontroller contains 32KB of memory, and also 2KB SRAM, and 1KB EEPROM.Power: The IC is provided up to 12 V of external power, RGB LED with Common Cathode configurationĪn Arduino Uno consists of a 14 digital input and output pin, 6 analog input pins, one USB pin, one 16MHz resonator, 16 MHz quartz crystal, a power jack, an ICSP header, and an RST button.

For a better result, we use PWM and Arduino Uno modules along with an RGB LED circuit. The desired color output can be obtained from RGB LED using CCR – Constant Current Resource or PWM technique. Common Cathode Configuration The Color Setting of an RGB LED on Interfacing with an Arduino Uno
