IR Sensor

The next sensor I have been experimenting with is an IR (infra red) sensor. This is the perfect sensor that can be activated with a simple TV remote control.

A 220ohm resistor in series with the IR sensor. This sensor is connected to the battery pack. Here is how it’s broken down.

Pin 1 is connected to the resistor and LED (anode or cathode??). Pin 2 (middle) is connected to the negative terminal of the battery pack. Pin 3 is connected to the positive terminal of the battery pack. LED (cathode, anode) are connected to the positive terminal of the battery pack.

A random TV remote control button is pressed to activate the sensor and turn the LED on.

Ensure that the LED is connected with the correct polarity by testing it with just the battery, then with the battery and resistor.

Arduino’s have arrived

I am fortunate to be surrounded by very artistic, innovative and talented people who amaze me everyday with their projects. I attend Nuit Blanche and in awe of the various interactive projects on display. Over the past few years I have had great discussions with Alison from Maker Junior and attended a Maker Faire or two. I had heard about the Arduino and the ability to make some interesting projects and finally took the plunge and attended a session by Darcy on Arduino Day.

Although I did not have an Arduino myself there were quite a few to go around so I got a chance to play. I managed to get Blink working and it was time to leave.

I have ordered a couple from Spark Fun and now that they are here I am eager to get started but can’t seem to make it out to any of the meetups’ due to schedule conflicts.

I am not sure what to do next.
