Took me a little while to get started but I’ve managed to wire 2 PIR infrared sensors with an Arduino to sense motion either on the left or on the right side. The result will trigger an LED to represent each PIR sensor then I also added in a servo to be controlled – so […]
This example shows you how to answer a HTTP request using an Ethernet shield. Specifically, it connects to pachube.com, a free datalogging site. The example requires that you set up a pachube.com account, as well as a pachube feed (for more information on setting up an input feed, please click here). Your Ethernet shield will […]
There are a lot of things this world needs at the moment. One of them is a better mouse trap. Mice are getting smarter every day and if we’re not careful we’ll end up with Planet of the Mice. Luckily, with the help of a Makerbot Replicator 2 (its enormous 410 cubic inch build volume […]
So having worked out that I can make a remote for my Nikon D80 to do some timelapse photography. I started thinking of things I can do to trigger the remote, below video shows it working but you’ll need sound to hear the shutter going. First of all check out my tutorial for making the […]
This example simplifies the task of collecting data from the Esplora’s accelerometer and graphing it with your computer. The Esplora sends keypresses to a connected computer about the state of the accelerometer. If you open a spreadsheet application, you can log the data from the accelerometer. To start and stop the datalogging, press the down […]
I’m cheap and skint, yet I want to do timelapse photography with my Nikon D80 DSLR. Unfortnately that requires spending some cash on an intervalometer for time lapse photography which will set me back a sizeable chunk of cash. Or I could get a remote or get the trigger system then create a delay mechanism […]
A guide to using the SRF05 Distance Sensor with Arduino in order to calculate distances from objects. In this case I’m also altering the output of an LED with PWM according to how close an object is to the sensor. So the nearer you are the brighter the LED. So if we start with the […]
This sketch shows you how to read the Esplora’s temperature sensor. You can read the temperature sensor in Farhenheit or Celsius. Circuit Only your Arduino Esplora is needed for this example. Connect the Esplora to your computer with a USB cable and open the Arduino’s Serial Monitor. Temperature to send data to your computer from […]
Knock Block: a modern knocking framework Man has long wrestled with Time. Also, with knocking on things and not getting the time of day. We propose a knocking platform through which these fundamental needs are met. This is illustrated with the Knock Block KUI and accompanying Clock Knock Block application. The Knock Block possesses realistic […]
This week is all about analog inputs for the Arduino. I’ll show you how you can use a voltage divider circuit (see episode 3) and a variable resistor to make an analog sensor. We’ll also use a Sharp IR distance sensor as an analog input to detect distance and movement (with some clever programming). By […]
