The L293D Motor driver shield is one of the best way for controlling DC, Servo and Stepper motors especially if you are using Arduino UNO or MEGA in projects like robotics and CNC. Another rather...
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...
One of the most useful things you can do with an Arduino is control higher voltage (120-240V) devices like fans, lights, heaters, and other household appliances. Since the Arduino operates at 5V it can’t control these higher voltage devices directly,...
Dc motors are used in a number of applications especially robotics. The main challenge with using these motors with microcontrollers is that they cannot be connected directly to the microcontroller I/O pins. This is because...
An obstacle avoiding robot is an intelligent device that senses any object in front of it and avoids it by turning in a different direction. In this tutorial we are using Arduino to control an...
4 digit 7-segment displays are among the commonest display components in several of our household appliances like digital radios, clocks, refrigerators, air conditioners and many others. They are used to display information in form of...
One of the common applications of IR receivers is in remote controlled car using Arduino as shown in this tutorial. The other major component of this project is the L298N motor driver whose functioning has...
An IR remote control enables us to control devices from a distance through wireless communication. Home appliances like radios and TV sets can be a pain if you have to always get up from your...
