Nettet26. nov. 2012 · Connect a 9-12V power supply to the Arduino so that Vin supplies the high voltage to the LED strip. If you want, you can also just use a separate wire that connects to a power supply that provides about +12V. Make sure to connect the ground of that supply to the ground of the Arduino/MOSFETs! TIP120's can handle up to 5 Amps of … NettetConnect one of the button pins to pin 11 through a ~ 5 kOhm resistor, and the other pin to ground (GND). Press the button. You can now use ‘digitalWrite’ or other other functions to switch on an LED, relay, adjust PWM duty cycle (for example, increase the brightness of a lamp) whenever the button is pressed.
NettetThrough Hole LED. If the LED has two leads, one longer than the other,the longer lead is the postive (also known as the anode) lead. If the LED has two leads with leads that are equal in length, you can look at the metal plate inside the LED.
