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 ...

This is just a simple program I wrote for an Arduino Mega 2560 board with a generic ultra-sonic sensor and a 16x2 LCD display board. The main point for me is just to learn how to write C++ and gain ...

S = distanceCm T = duration V = sound speed (340m/s) (0.034cm/µs) NOTE. We are dividing result because when the ultra sound reaches the object, it reflects back on the same distance and distnace value ...

Here is the schematic diagram of a Human-following robot circuit. This design incorporates three ultrasonic sensors, allowing distance measurements in three directions front, right, and left. These ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...
