Nettet6. mai 2024 · Those resistors/LEDs are not exactly in parallel. Each LED-resistor pair is connected to a different output pin. With about 2V across the LED and 3V across the resistor you'd have about 14mA (3V/220 Ohms) coming out of each pin and through each LED-resistor pair and that's OK. If this is going to be your hobby I strongly recommend … Nettet7. jul. 2024 · Common Cathode RGB LED. In a common cathode RGB LED, the cathode of the internal LEDs are all connected to the external cathode lead.
