Byte Insight

Light Sensor

This circuit is based on the ARDX 09 circuit from Oomlout.  It shows how the Arduino can monitor light values using a Photo Resistor and adjust a LED in response. 

Arduino

The amazing versatile Arduino microprocessor board that can be used in many projects.

Serial

The Arduino Serial functionality can be used for both debugging and sending data to and from the device via other communication channels such as BlueTooth.

Zumo Inertia

The Zumo Robot is fitted with a set of Inertia Sensors that can be used to detect collisions and determine bearings/direction. The later 1.2v of the Zumo Shield includes a Gyroscope.  

Potentiometer

This circuit is based on ARDX 8 which uses a potentiometer to change the flash rate of an LED.  

Push Button LED

This simple flashing LED (Light Emitting Diode) circuit is based on the ARDX 07 circuit from Oomlout.  It serves as an excellent introduction to combine inputs and outputs.   It uses a Pull Down Resistor.  

Larsen Scanner

This project is based on ARDX 2 from Oomlout and uses multiple LEDs to create simple patterns.  It gets its name from Glen A. Larsen who wrote the Knight Rider TV Series.  It uses for loops, which are one of the key repetition constructs in computing.

Zumo Robot

The Pololu Zumo Robot is a dual motor rubber tracked robot that fits inside the 10cm x 10cm rule for Mini Sumo Robot Competitions (Click here to see a video). Powered by 4 x AA Batteries it is controlled by an Arduino Uno and the Zumo Robot Shield working in tandem.

Zumo Lines

The Zumo Robot Shield can be fitted with a Reflectance Sensor Array that allows it to solve different line/maze style problems. The Zumo Shield libraries provide methods to help read values from the sensor array. Packages and installation instructions can be downloaded from GitHub and once installed the sensor library can be included from Sketch > Include Library.  The sensor array uses the QTR sensors and therefore their library must also be included (installed as standard).

Ardunio Bluetooth

It is with mixed emotions that I purchased a Maplin N97DG Bluetooth Shield for the Arduino.  I think its a good thing for Maplin and the Buildr community that Maplin are putting some high street umph behind Arduino and hobbyist electronics but I still reel at the whole mega corporations thing – can’t have everything I guess!
