Hello, I'm new to electronics and I'm trying to build a led array. Youtube videos helped me in getting a pretty good idea of what should be done.So right now I'm planning on using GPIO pins of a raspberry pi to control the array. My doubt is "The output voltage of GPIO pins is around 3.3V. How can I control an array of high power LEDs".
@adamaero Thank You. Relay seems to the trick. Lets say I'm making a 9x9 led array I would need 9 individual relays right? Is there any way to use single component to do the job?
