Arduino Class - Working With Sensors - Part 2


Location image of event venue


Come join us at Education Center in Plano TX to learn about the sensors you can use with the Arduino and other micro controllers. In this class we will be covering the following:

Ultrasonic distance sensor ( (10:11) In this presentation you will learn about how to measure distance using an ultrasonic distance sensor. This is a fairly sophisticated sensor that carries out a quite involved function when it comes to the physics of its implementation, however, as you will see, its application is as simple as it can be. You will also learn how to use a more advanced function of the Arduino language, the pulseIn function, through which you can time external events.

Detecting acceleration ( (6:22) In this presentation, you will learn how to use a common 3-axis accelerometer, the ADXL335, to accurately measure the acceleration applied to an object. At the end of the presentation, you will be invited to create your first non-trivial circuit using this accelerometer.

Line sensor (infrared) ( (3:36) In this presentation, we look at the infrared line sensor, a sensor that can detect the reflection of infrared light that it emits of nearby objects. Sensors like this are used in toy robots, for detecting colour, tracking objects, even in measuring pulse in medical equipment.

Tilt and impact ( (8:54) In this presentation, you will learn how to use a simple sensor that can detect the shock of an impact or being upside down. Even though in an earlier presentation we learned about the accelerometer, a sensor that can give us a lot of details about impact and the forces applied to it from which we can derive information about orientation, sometimes our needs are simple enough no not warrant using something as sophisticated as that. A simple switch that engages depending on its orientation or if something hits it is enough in such cases. Parts Needed
