Arduino SRF08

The speed of the sound in the dry air (20° C) is around 343 m/s. Send a short ultrasonic pulse at Frequency of 40Khz in the air, and try to listen to the echo. Of course you won’t hear anything (only a little click noise), but with an ultrasonic sensor the back pulse can be detected. If you know the time of the forth & back travel of the ultrasonic wave, you know the distance, divide the distance by two and you know the range from the ultrasonic sensor to the first obstacle in front of it.

A new topic about about alternative power sources for the arduino board (in my case arduino duemilanove version).

For measurements and experimentations outdoor or while you sitting in the train and wasting your time, you could use a alternative power source for the tiny programmable monster.

Alternative power source I – battery’s/rechargeable batteries
You can [Read more…]

Yesterday I connected my MacBook Pro to Arduino Duemilanove, and I was a little bit confused. I was not able to select the tty.usbserial Port to transfer my compiled code to arduino.

If you are using a USB Arduino you need to install a virtual COM Port driver to be able to connect MacBook to your Arduino.
