Pavi98 Member Oct 6, 2023 #1 Hello there, I'm working on a project to control 20 RGB LEDs by using arduino PWM pins. Can you give a proper circuit diagram to power those LEDs? Thank you

danadak Well-Known Member Most Helpful Member Oct 6, 2023 #3 Are the LEDs all bare RGB, no driver on them of any kind ? Do you want static drive or can you use scanned matrix type drive ? Part number for LEDs and your available power supply for the LEDs ? https://pdfserv.maximintegrated.com/en/pg/led-drivers-for-general-lighting.pdf https://www.infineon.com/dgdl/Infineon-Z8F64898475_LED_driving_concepts_and_Linear_LED_drivers-ApplicationNotes-v01_20-EN.pdf?fileId=5546d462696dbf120169b4cb29224b30 Regards, Dana.
