This is a another sample demonstrating Arduino MEGA, LCD screen and SRF05 ultrasonic range finder. The distance measurement from SRF05 is displayed on the LCD screen in centimetres.
Different from Infra Red range finder witch uses IR light to measure distance, ultrasonic range finder sends short high pitch sound pulses and measures the time for the [...]

The Arduino MEGA I got had and issue with automatic reset during sketch upload. The error message in the Arduino IDE looked something like this:
<pre>avrdude: stk500_getsync(): not in sync: resp=0×00

I had to hit Reset button just before uploading a sketch. This issue was due to some sort of defect in [...]

This is a bit enhanced version of the “hello world” blink application for Arduino: traffic lights emulator. The top three LEDs control car traffic and the bottom two are fore pedestrians.
int carRedPin = 13;
int carYellowPin = 12;
int carGreenPin = 11;
int pedestrianRedPin = 10;
int pedestrianGreenPin = 9;
// The setup() method runs once, when the sketch starts

This was one of my first projects to try out various features of Arduino. I got this 2×16 LCD screen from Oomlout. The breadboard schematics came together with the LCD screen and is relatively simple.
Here is the sample code I uploaded to the controller:
// include the library code:
#include <LiquidCrystal.h>
// initialize the library with the numbers [...]

This was my first experience in this type of event, so I came without any expectations. :) Once the the welcoming announcements were made everybody started hacking either by going to beginners workshops or working [...]
