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...
The MAX7219 led matrix with Arduino is among the most widely used components for displaying text in applications like billboard messages and digital clocks. However these matrix displays come in various types and as such...
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 obstacle avoiding robot is an intelligent device that senses any object infront of it and avoids it by turning in a different direction. In this tutorial we are using Arduino to control an ultrasonic...
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 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...
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,...
