Hello everyone so im planning on using the arduino mini to control my 256 LED array, which is this
it has a 5V,GND,DIN on one side and 5V and GND in the middle
im aware that arduino can not provide enough power so a separate power source will be needed. I have a 5 volt 12 AMP power supply,im just a little confused on how to hook it up. Do i connect the arduino 5 volt, V+ of the power supply and 5V of the LED strip all in one connection? Ive seen diagrams where all the 5 volt pins are connected together and some where only the ground is connected. Im not to sure how to wire it with this particular 256 LED array. Some one also said to use a capacitor on the 5 Volt and ground of the arduino pin but again alot of different information. What would be the proper way to connect the power supply and arduino to this strip? Do I just only use the Data pin of the arduino and only the power supply for all the 5 volt and ground connections of the LED array? Thank you for any clarification.
