Surveillance RoboCar based on ESP32 CAM Module

Harsh Sehgal 0 Comments

If you are thinking of building a Web-controlled surveillance car using the ESP32 CAM module then this tutorial will help you out in building the same. Web-controlled surveillance cars can be built using the ESP32-CAM module. Apart from the ESP32-Camera module, we will need 4 DC motors with its Robo car chassis and L293D motor driver module...

Line Follower Robot using Arduino and L298N Module

Harsh Sehgal 0 Comments

The line follower robot is an automated vehicle that follows a visual black line or path on the surface. This visual line is a path on which the line follower robot moves. It uses a black line on a white surface, or you can also adjust it as a white line on a black...

How to Control Servo Motor with Arduino Uno?

Harsh Sehgal 0 Comments

Let’s take a look into a simple interfacing project this time. This is actuator interfacing with Arduino Uno and the actuator being servo motor, specifically SG90 servo motor. SG90 is a lightweight (just 9g) and tiny servo motor which has quite good output toque. We can use Arduino IDE to code this servo and...

Distance Measuring with LED Notifier using HC-SR04 Ultrasonic Sensor and Arduino

Harsh Sehgal 0 Comments

In this tutorial, we are going to learn how to use ultrasonic sensor HC-SR04 interfacing with Arduino and measure the distance which will be notified by 7 LEDs. As we move closer to the sensor the  LED will glow consecutively and vice-versa.   HC-SR04 Ultrasonic Sensor Pinout The sensor has 4 pins. 5volts is...

Security Alarm using HC-SR501 PIR Sensor and Arduino

Harsh Sehgal 0 Comments

In this Arduino tutorial, we are going to learn how to use a motion sensor to sound a piezoelectric buzzer. The motion sensor used here is a PIR sensor which stands for Passive Infrared Sensor. This is great for an intrusion detection circuit or burglar alarm circuit. Whenever the motion sensor senses movement the piezoelectric buzzer will...
