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.…
This example uses the Keyboard library to log you out of your user session on your computer when pin 2 on the ARDUINO UNO is pulled to ground. The sketch…
This example shows you how to read an analog input at analog pin 0, convert the values from analogRead() into voltage, and print it out to the serial monitor of…
This example will show you how to read an analog input on analog pin 0. The input is converted from analogRead() into voltage, and printed out to the serial monitor…
This example demonstrates the use of the analogWrite() function in fading an LED off. AnalogWrite uses pulse width modulation (PWM), turning a digital pin on and off very quickly with…
LEDs are small, powerful lights that are used in many different applications. To start, we will work on blinking an LED, the Hello World of microcontrollers. It is as simple…
