The IR LED is same aspect as the normal LED. We can only see light rays from violet to red whose wavelength travels from 380 (violet light) to 750nm (red light). These rays are not able to be seen by the human eyes as it’s not in the range of human visible electromagnetic radiation spectrum. Note: Complete technical information can be found in the IR LED Datasheet, linked at the bottom of this page.Īn IR LED is a specially designed LED which transmits infrared rays. Easy to use with breadboard or perf board.Power Dissipation of 150mW at 25℃ (free air temperature) or below.Soldering Temperature should not exceed 260 ℃.

Temperature for storage and operation varies from -40 to 100 ℃.

Forward current (IF) is 100mA (normal condition) and 300mA (max.).

There are two ways to adjust the brightness of an LED.The IR LED or Infrared LED has polarity i.e.it has a positive and negative pin. The pin which is long is the positive pin (anode) and the pin which is short is the negative pin (cathode) as shown in the above IR LED pinout. There are several ways to blink an LED, but one of the easiest ones to both build and understand is the blinking LED circuit based on a NOT gate. But normal LEDs won’t blink without this circuit. If you want to blink an LED, you need to build an oscillator circuit that will turn the LED on and off. The only time you don’t need the resistor is when you have a battery or other voltage source that provides exactly the voltage your LED needs. That’s why the resistor is there – to control how much current that goes through the LED. If you run too much current through an LED, it will get really hot and break down. For most standard LEDs, if you have a voltage of around 9V and use a resistor in series of around 1 kΩ to 10 kΩ, the LED will “grab” the voltage it needs. You don’t have to worry too much about the voltage. The easiest way to find this information is to look it up in the datasheet (look for LED forward voltage and Test Current) – or ask the store where you bought it.

But this varies among different LED types. Usually, an LED needs about 2-3 volts and about 1-10 mA to light up.
