If you do not know about LED and ultrasonic sensor (pinout, how it works, how to program ..), learn about them in the following tutorials: -Arduino-LED tutorial ...

We know everything produces sound wave just by existence and effect flow of air around them with their natural frequency. These frequencies are beyond hearing range of humans. Wave of frequency range ...

The ultrasonic sensor with Arduino allows us to measure distances through ultrasound. It is very common to find this type of sensor in today’s cars. The objective is to show how we can build real ...

Adding cameras and vision algorithms to your projects and robots might sound cool but sometimes it becomes expensive in terms of both capital and time. When the task at hand is much simpler like ...

// C++ code // include the library code: #include // initialize the library with the numbers of the interface pins LiquidCrystal lcd(12, 11, 5, 4, 3, 2); int ultrasonic = 0; long ...

An automatic floor cleaning robot is not a new concept. But these robots have a major issue. They are very expensive. What if we can make a low-cost floor cleaning robot that is as efficient as the ...

Abstract: A simple robotics project simulated in Tinkercad based on Arduino Uno. It uses ultrasonic sensors for obstacle detection and can do basic movements using DC motors. The primary objective of ...

Abstract: Ultrasonic Sensor Explorer (USE) is a cheap mobile robot for mapping. Instead of expensive laser sensor, it uses cheap ultrasonic sensor HC-SR04 with range up to 4 meters. The chassis of the ...
