Arduino Basics

Introduction: This project utilises the HC-SR04 ultrasonic sensor to scan for nearby objects. You can program the Arduino to sound an alarm when the sensor detects an object within a specific vicinity. Connecting it to a computer allows data to be plotted to make a simple sonar scanner. The scanning ability is made possible through the use of a hobby servo motor SG-5010, and an Adafruit motor shield v1.0. This project could easily be extended to provide object avoidance for any robotics project. This tutorial was designed so that you could see how the components interact, and also to see how you can use and expand the functionality of the motor shield. Parts Required: Freetronics Eleven or any compatible Arduino. Adafruit motor shield v1.0 HC-SR04 Ultrasonic Sensor MG-995   or SG-5010 Standard servo Mini Breadboard 4.5cm x 3.5cm Female header pins to allow easy access to the analog pins on the Motor Shield Piezo buzzer - to sound alarm 9V Battery and Battery Clip Wires to conn...

Introduction: The IRTEMP module from Freetronics is an infrared remote temperature sensor that can be incorporated into your Arduino / microcontroller projects. It can scan a temperature between -33 to +220 C, and can be operated using a 3.3 to 5V power supply. It can be powered directly from the Arduino 5V pin.  This module can also provide an ambient temperature reading if required. The Servo used in this project is a SG-5010 standard servo which will be utilised to display the temperature reading from the IRTEMP module. Parts Required: Freetronics Eleven or any compatible Arduino. Freetronics IRTEMP module MG-995   or SG-5010 Standard servo Mini Breadboard 4.5cm x 3.5cm Protoshield and female header pins (not essential - but makes it more tidy) 9V Battery and Battery Clip Wires to connect it all together Gauge parts: Paper (to print the face of the gauge), and some glue to stick it to the wood. MDF Standard panel (3mm width) - for the top and base of the gauge. Galvaniz...
