A simple server that distributes any incoming messages to all connected clients. To use, open a terminal window, telnet to your devices IP address, and type away. Any incoming text will be sent to all connected clients (including the one typing). Additionally, you will be able to see the client’s input in your serial monitor

This example shows you how to make a HTTP request using an Ethernet shield. It returns a Google search for the term “Arduino”. The results of this search are viewable as HTML through your Arduino’s serial window. Circuit The Ethernet shield allows you to connect a WizNet Ethernet controller to the Arduino via the SPI

In this example, you will use your Ethernet Shield and your Arduino to query a Network Time Protocol (NTP) server. This way, your Arduino can get the time from the Internet. Circuit The Ethernet shield allows you to connect a WizNet Ethernet controller to the Arduino via the SPI bus. It uses pins 10, 11,

This sketch connects a voice call from your GSM shield and Arduino to a remote phone number entered through the serial monitor. You’ll need to attach a speaker and microphone to hear the connected phone and send your voice. First, import the GSM library #include <GSM.h> SIM cards may have a PIN number that

Arduino projects, make arduino rpm counter with arduino. Instruction;1) Connect all jumper wire as shown in diagram. 2) Connect IR LED to digital pin 13. 3) Connect IR Phototransistor (dark) to digital pin 2. Make sure shorter lead connected to digital pin 2 and longer lead to Ground. Upload this code to your arduino/** Optical Tachometer** Uses an IR LED and IR phototransistor to implement an optical tachometer.* The IR LED is connected to pin 13 and ran continually.* Pin 2 (interrupt 0) is connected across the IR detector.** Code based on: www.instructables.com/id/Arduino-Based-Optical-Tachometer/* Coded by: arduinoprojects101.com*/

In arduino projects, you might add servo to your projects. This short tutorial, show you the basic how arduino and servo works together. Instruction; 1) Connect all jumper wire as shown in diagram. 2) Connect the signal wire from servo to digital pin 9. Upload this code to your arduino /* Servo Basic Understanding the basic of servo in arduino projects. Sweep

In this project, we will learn how to use a speaker (peizo sounder) and use switch button to change the pitch of the sound. Sorry about this one, you might find it a bit difficult to digest at first, and I didn’t realise it’s actually harder than it sounds. Anyway, spend some time on the code,

7-Segment LED Display is a very useful component, but also a very confusing and difficult piece to use for beginners. It won’t be difficult once you get it working for the first time. This is what you will get at the end of the tutorial (part one): It basically consists of 7 LEDs, (8 if include

My First ever Robot. It tracks objects using Infra-red sensors, and has basic AI that follows and avoid objects. I will describe the how I made this robot, and upload some videos. Version 1 (16 Dec 2011): —————–The components used ———————- I actually planned this robot before making it. I didn’t use all the parts

Arduino HC-SR04 The Arduino HC-SR04 is different from most of those commonly seen on the market, which have 4 pins compared to 3 pins. But the operation principle is the same, transmit signal, and depends on when the signal is received to estimate the distance. Arduino HC-SR04 not only inexpensive but also practical, use a
