In this blog, we will discuss about L293D Pin Diagram its working, and its interfacing with Arduino. L293D can drive two DC motors simultaneously, with up to 600mA current in each channel. It receives a control signal from microcontrollers such as Arduino, ESP32 Dev Module, etc. based on these control signals it controls the direction […]
In this project, we are making a Bluetooth Controlled Car using ESP32 Dev module. There is a reason why we have chosen ESP32 instead of any other board like Arduino. here is the reason why we have chosen it. ESP32 is now becoming more famous due to its great features like inbuilt Bluetooth and Wi-Fi modules. Also, it has […]
Hey, folks in this project we will be making a line follower robot using Arduino Uno. As a beginner in robotics, making a line follower robot is a good idea. By this, you can learn how a robot works? A line follower robot follows a black line over a white surface using its two IR […]
Making a water level indicator and pump controller using Arduino is a very good idea. We can fully automate our water supply system using sensors, electronics, and some programming knowledge. The water pump controller which we are making automatically switches ON and off depending on the level of water. Also, it displays the level of […]
Hey folks, have you used an ultrasonic sensor in your projects! Do you know how it works? In this project, we will use an ultrasonic sensor without Arduino for object detection. We will interface ultrasonic sensor with a 555 timer to control a DC motor. How ultrasonic sensors work? As the name suggests an ultrasonic […]
Hey folks, in this article we will see what is a seven-segment display with Arduino Interfacing. How to connect a seven-segment display directly to the Arduino without any decoder IC. Also, we will code Arduino to count Arduino from 0 to 99 on seven segment display. Let’s get started. What is a seven-segment display? A […]
