In this tutorial, I will explain about Interfacing HC-05 Bluetooth Module with Arduino Uno. HC-05 uses bluetooth classic and can be configured in master or slave modes. It can be interfaced with a microcontroller using UART.
In this tutorial we will learn about Interfacing DHT11 Temperature and Humidity sensor with Arduino Uno. The term DHT is an abbreviation of Digital Humidity and Temperature sensor. DHT11 consists of a resistive humidity sensor, NTC temperature sensor and an 8-bit microcontroller providing cost effectiveness, anti-interference ability, excellent quality and fast response.
In this tutorial we will learn how to interface L298N motror driver with Arduino Uno. You might be thinking why we need L298N for controlling a motor. The answer is very simple, Arduino board or a microcontroller IO pins don't have enough current/voltage driving capability to drive a motor. For driving the motor in both directions (clockwise and anti-clockwise) we need to use an H-Bridge. Please read our article H-Bridge - DC Motor Driving for more...
In this tutorial we will learn how to interface Tilt Sensor with Arduino Uno. As the name suggests, it is an electronic device used to detect the orientation or tilting of an object and provides digital output based on the orientation. It behaves like a normal ON - OFF switch that is controlled by tilting. Tilt sensor consists of a mercury ball and two contacts in a sealed enclosure, in which the mercury ball will short the leads based on...
In this tutorial we will learn how to interface servo motor with Arduino Uno. Servo Motor is an electrical linear or rotary actuator which enables precise control of linear or angular position, acceleration or velocity. Usually servo motor is a simple motor controlled by a servo mechanism, which consists of a positional sensor and a control circuit. Servo motor is commonly used in applications like robotics, testing automation, manufacturing automation, CNC machine etc. The main characteristics of servo motor are...
In this tutorial we will learn about integrating HC-SR04 ultrasonic distance sensor with Arduino Uno. Ultrasonic sensors are commonly used for obstacle detection and distance measuring applications. The sensor works on the same principles of a radar system, which converts electrical energy into acoustic waves and vice versa. The HC-SR04 ultrasonic sensor is based on the principle of SONAR, which is an abbreviation of Sound Navigation Ranging. This sensor is used in many hobby projects where there is a need...
GPS stands for Global Positioning System. GPS module find the location (latitude, longitude, altitude) by comparing the time taken for receiving signals from satellites in its vicinity. GPS offers a great accuracy and also provides other data besides position coordinates.
