I am after some technical help. I need to independently operate 29 lights. (each light must have the ability to turn on/off without depending on other light states)
Now I want to do this with a Raspberry Pi and use its GPIOs. I have no issues with the programing side, but I have no idea what components, register, boards I need in order to achieve this.
As far as I am aware the Raspberry Pi has 8 GPIOs and thus 2^8 256 components can be controlled? What do I need to achieve just 29?
I have no issues with the programming part, but please be as detailed as you can due to the fact this I am very new to the electrical side of this. Thanks
