Using BMP180 for temperature, pressure and altitude measurements

The BMP180 is a new generation digital barometric pressure and temperature sensor from Bosch Sensortec. In this tutorial, we will briefly review this device and describe how to interface it with an Arduino Uno board for measuring the surrounding temperature and pressure. We will also discuss about retrieving the sensor altitude from its pressure readings. Experiment setup Bosch Sensortag’s BMP180 ...

Intelligent Buggy featuring 4Duino-24

4Duino Intelligent Buggy project demonstrate how does uCAM-II works. This project also utilized two 4duino communicating using Server-Client architecture over TCP. It also uses a buggy car which carry the 4duino server and uCAM-II. By using built-in ESP8266, 4duino client sends a request to 4duino server to move the buggy and capture photo via wireless communication. Server-Client architecture is a network ...

Arduino 433Mhz RF Wireless Data Transfer

The most practical and cool way of sharing data from 1 Arduino to another is by far using a radio transmitter and receiver. The simplest form of wireless transmission (I could find) is the 433Mhz ASK modules. They come in pairs, a receiver and a transmitter. They are ridiculously cheap, selling at $1 or less a pair!! These modules provide simplex 1 way data transmission, in order to get a 2 way communicatio ...

GPIO Control from Web Browser featuring 4Duino-24

In this project, we will learn how to control the on board 4Duino LED via I/O port (D13) from web browser. In built ESP8266 Wi-Fi module is configured as server enabling the 4Duino to receive commands from a web browser (client). How it works Note: This project could be carried out only if the Client and the Server are in the same network because your home router prevents the 4Duino server to be accessed fr ...

Pet Food Dispenser featuring 4Duino-24

In this project, we will use a 4Duino and several IR sensors to create a simple pet food dispenser. 4Duino checks whether a food tray contains enough food or not. It is programmed to read IR values from each sensor. These values change depending on the amount of food in the container.  The feeding time can be set by the user via the graphical user interface. The device continuously checks the time from an N ...
