The files below provide an overview of Scratch being used for data logging.
You may have expensive bespoke data loggers in your school.
I would not necessarily advocate replacing them with Scratch but this is a great way to learn about data logging and the way in which data loggers interface with the real world.
This is also a very practical context for some more advanced programming.
Finally what a great way to fulfil the Physical Computing requirements of the new Computing POS.
1. Data Logging Thermistor example shows how an input from a sensors could be combined with a game.
2. Data Logging example is a simple data collection data display activity.
3. Data Logging - Picoboard is an interesting paper written by Myra VanInwegen - a great start for data logging beginners.
4. Temperature Graph Real Time.
5. Thermometer Cat - a fun way to measure temperature using a calibrated display.
PicoBoard - (see below) these can be purchased for about £40. They are and input only device. The board has a number of built in sensors for light and sound, it has four inputs for resistance measurement, a slider to give a variable input and a push to make switch input. It can be used with cheap, off the peg, components such as LDRs, and thermistors purchased from Maplins for pence rather than pounds.
