This example is composed of an Arduino UNO, having an Ethernet Shield coupled to connect to the Internet, the data is sent through MQTT, with the collection of a DHT11 sensor for temperature information and humidity of the environment.
The economy and simplicity of the network-transparent SIMPL toolkit makes it an ideal choice for the Raspberry Pi. In this article, we describe how to use the SIMPL toolkit to communicate between a Rasp Pi and an Arduino board.
In this project, we make the Arduino to obtain live twitter feeds from the Internet and display it on an LCD. We just modified the library so that now it displays the feeds on the LCD instead of the Serial Monitor.
This project is a way to control an Arduino or my Arduino atmega644/1284 clone via a PC or a human-machine interface connected to the Arduino Ethernet shield. You will create a SCADA system to control your system from a long distance.
This project describes an audio signal from a microphone are amplified and input to an A/D input on the Arduino. The Arduino firmware samples and digitizes an audio signal at a 20kHz rate, and transfers the data over a serial port to a PC at 230400 baud and stream the audio signals over a local network.
This is an Arduino-based project to remotely control a bank of AC household current outlets through an Ethernet network. The AC outlets are controlled based upon Telnet commands and the system has built in password protection.
Sometimes when I take a bath, the water stops. I checked that the water tank is empty and I have to call the water engineer to fix the water. I wish I could've known the water problem earlier. So now, with Cayenne, I have an idea to make My Water System connected to my mobile device
