How useful could the Arduino Yun be in computer vision in a robotics project?
0 votes

I am guessing not very useful. Image recognition is quite CPU-intensive, and Arduinos are slow, memory-starved, 8-bit processors. The Unix side of the Yun runs at 400 MHz, which is quite a bit ...

A few things. As somebody else suggested, try a normal red LED and make sure that works first. Note that your resistor is allowing too much current through the LED. A high-current LED might tolerate ...

You need to learn some absolute basics about electronics so you don't fry your arduino. (Don't exceed the current limits on the i/o pins. How to use Ohm's Law to calculate current. How to tie inputs ...

Strips of LEDs like WS2812Bs need a high current 5V supply, with NO current limiting resistor. You'll need a very high current regulated 5V supply, and would probably be better off using a separate 5V ...
