In this topic, we will discuss Network Communication in Arduino. The CC3000 WiFi module from Texas Instruments is a small silver package, which finally brings easy-to-use, affordable WiFi functionality to…

The wireless transmitter and receiver modules work at 315 Mhz. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link.…

In this chapter, we will use the Arduino Tone Library. It is nothing but an Arduino Library, which produces a square wave of a specified frequency (and 50% duty cycle)…

A Stepper Motor or a step motor is a brushless, synchronous motor, which divides a full rotation into a number of steps. Unlike a brushless DC motor, which rotates continuously…

A Servo Motor is a small device that has an output shaft. This shaft can be positioned to specific angular positions by sending the servo a coded signal. As long…

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…
