In this chapter, we will interface different types of motors with the Arduino board (UNO) and show you how to connect the motor and drive it from your board. There…

Pushbuttons or switches connect two open terminals in a circuit. This example turns on the LED on pin 2 when you press the pushbutton switch connected to pin 8. Pull-down…

The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings…

PIR sensors allow you to sense motion. They are used to detect whether a human has moved in or out of the sensor’s range. These are commonly found in appliances…

Water sensors brick is designed for water detection, which can be widely used in sensing rainfall, water level, and even liquid leakage. Connecting a water sensor to an Arduino is…

The Temperature Sensor LM35 series are precision integrated-circuit temperature devices with an output voltage linearly proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors…

In this section, we will learn how to interface our Arduino board with different sensors. We will discuss the following sensors − Humidity sensor (DHT22)Temperature sensor (LM35)Water detector sensor (Simple…

This example listens for a byte coming from the serial port. When received, the board sends a keystroke back to the computer. The sent keystroke is one higher than what…

Using the Mouse library, you can control a computer's onscreen cursor with an Arduino Leonardo, Micro, or Due. This particular example uses five pushbuttons to move the onscreen cursor. Four…

In this example, when the button is pressed, a text string is sent to the computer as keyboard input. The string reports the number of times the button is pressed.…
