Nettet22. mai 2024 · Connect the long leg of the LED (positive leg, called the anode) to a 220 Ohm resistor and then to digital pin 7. Connect the short leg (negative leg, called the cathode) directly to ground (any of the Arduino ports with GND on it, your choice). This is a simple circuit. The Arduino can digitally control this pin. Nettet18. okt. 2012 · Then a high output won't light the LED because the output FET is switched off. A low output will draw the 20 mA through LED, resistor and open-drain output. Note that this will invert the logic: in your first schematic the LED will be off when the output is active, in the second circuit it will be on with active output. edit

Nettet2. mai 2011 · An LED does not require a resistor on the anode side, or the cathode side. It does need current limiting somehow, and a resistor is one way to do that. make the voltage source very close to the forward voltage of the LED, relying on the LED's intrinsic resistance to limit the current to a safe level. NettetPlace a LED on the board between the row for 4b and the resistor. Remember an LED is directional, so you have to orient it correctly. The longer leg should always connect to the positive voltage (4b), and the shorter one to the ground (5). Orient the LED so that the longer leg is closer to the switch (positive), and have the LED cross two rows.
