Diy 11 Rgb Led Sequencer With Dual Mode Based On Cd4017 Youtube How to make rgb led sequencerhi friends in this video i have made an rgb led chaser circuit using arduino i hope you like this video please like share and su. Common cathode rgb led. in a common cathode rgb led, the cathode of the internal leds are all connected to the external cathode lead. to control each color, you need to apply a high signal or vcc to the red, green, and blue leads and connect the anode lead to the negative terminal of the power supply. common cathode rgb led pinout. Step 1: how the rgb leds work and electronic components in the circuit. the electronic components in the circuit are ; 5 rgb leds (cathode type) 10 ;1 k resistors (brown,black red)) 3; 470 resistors (yellow purple brown) arduino uno. wires. the rgb leds (see image 2) are 3 leds connected together with a common cathode (negative lead). Here's the led driver circuit. it's very simple. it uses an irblxxx n channel mosfet for each channel on the led strip. the led strip is common anode, meaning 12v is sent to the led strip, and the red, green, and blue led channels are controlled by providing ground on the respective connection to the strip.
