In our older how to guide, we have shown ir sensor to switch off led. These pins are numbered from 0 to 13.
Arduino Switch Led Circuit. Five leds are attached to digital pins 2, 3, 4, 5, and 6 in series through 220 ohm resistors. This tutorial will show you some basic concepts of resistors and how they can be used in your first led project with arduino.

We will set up the arduino ide on your pc/laptop and upload a sample blink program to the arduino. In the arduino ide open the serial monitor and send the characters a, b, c, d, or e to lit up the corresponding led, or anything else to switch them off. There are major four types of switches in arduino, which are listed below:

Spdt (single pole double throw) switch; Here the switch is connected to digital pin 4 (d4) and led is connected to digital pin 8 (d8) of arduino uno. Pushbuttons or switches connect two points in a circuit when you press them. In this sensor tutorial, we will use one magnetic door switch and an led for detecting if a door is open or not.

As upgrade of the project, we can use that ir sensor to switch off. You can notice that the led has a leg shorter than the other. It is a switch that has one input and one output. Connect the longer leg of the led to a digital pin (here pin no 8, you can change it). Here the switch.

The thing sounds like childish. There are major four types of switches in arduino, which are listed below: 8.5 use a magnetic contact switch with arduino. This project illustrates switching using a transistor. This tutorial will show you some basic concepts of resistors and how they can be used in your first led project with arduino.
