educ8s.tv has published a new Arduino Video tutorial:
High Power LEDs are very popular and low cost nowadays so I thought it would be a good idea to learn how control them with Arduino. So, I built a simple project that simply turns on a 4W Cob LED when the button is pressed. When the button is pressed again, the LED turns off. The LED is powered by 12V battery and it is controlled by the Arduino using a MOSFET. But let’s see how to build it.
