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 […]
This sketch shows you how to read information from the Esplora’s joystick and use it to control the movement of the cursor on your computer. You’re making your Esplora into a mouse! This sketch will take over the mouse movement of your computer. If you lose control of your cursor do the following : unplug […]
This example shows you how to read different analog sensors to change the brightness of the three colors in the RGB LED. In this example you will read the amplitude from the microphone, the amount of light on the light sensor, and the position of the linear potentiometer. These three sensors will control the intensity […]
This sketch shows you how to read the microphone sensor. The microphone will range from 0 (total silence) to 1023 (really loud). It uses the sound level to set a brightness level for the green LED. When you’re using the sensor’s reading (for example, to set the brightness of the LED), you map the sensor’s […]
This example is designed to be used with a Processing sketch. Processing is an open source programming environment. The application on the computer reads the sensors on the Esplora board and controls the buzzer and the RGB LED through a graphical interface. The image in the Processing application mirrors the Esplora board, so you’ll see […]
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*/ […]
This is basic for your arduino projects, input switch read from digital input. When ever switch pressed, LED will turn on. Instruction; 1) Connect cathode lead of LED (shorter lead) to ground pin and anode lead of LED (longer lead) to pin 13. 2) Add switch to breadboard, connect one of the switch […]
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 […]
