Among the most common challenges beginners find when using switches with microcontrollers like Arduino is the “floating pin” or “floating input”. To explain this phenomenon lets consider a simple connection used to turn an led...
Arduino voice control of devices can be done in a number of ways using voice recognition modules for example EasyVR Shield 3.0, ELECHOUSE Voice Recognition Module V3, Tigal SmartVR Voice Recognition Board, Grove – Speech...
In the previous tutorials we have seen how to control DC motors and Stepper motors using Arduino and the various types of motor drivers used. In this tutorial let us look at how to control...
In my previous tutorials I showed how the DS3231 RTC and SSD1306 OLED modules work and how they can be interfaced to Arduino. In this tutorial I’ll show how these two devices can be combined...
The MAX7219 led matrix display interfaced with Arduino can be used to make a real time clock with the help of the DS1307 RTC module as we are going to show in this tutorial. I...
RGB LEDs play a large part in applications like outdoor decoration lighting in cities, stage lighting designs, home decoration lighting and LED display matrix. Recently, RGB color mixing technology can also be found in LCD...
The HC-SR04 Ultrasonic sensor can be used to detect objects in a range of up to 13 feet away. In this tutorial this sensor is connected to Arduino to achieve this function. Ultrasound is high-pitched...
Sound is a very important aspect in a number of projects and in this tutorial I will show you how we can make a simple sound dependent clap switch which can be used to control...
The MQ2 gas sensor is used for detecting the levels of various gases around the area, so you can utilize this sensor as a gas leak monitoring system, in fire alarms and air quality monitoring...
A light sensor with Arduino is a simple demonstration of how Arduino can be used in home automation, in this case controlling the lighting of bulbs depending on the amount of light in a given...
