Time for action – recording the resistance of a thermistor over time
The following exercise walks us through creating a script that records resistance values based on an interval. If you don't have a PicoBoard or a thermistor, you could alter the script to record loudness. We're going to be setting up this project as a way to conduct experiments with resistance, and because we're using the thermistor, we can draw some conclusions about temperature.
We'll create the framework to do the monitoring, and at the end of this exercise, you'll have a thermistor measuring the resistance at room temperature. (Non-PicoBoard users can set this framework up with the loudness block to capture sound.)
We'll discuss ways to apply our environmental monitor in other interesting ways after we get the framework finished up. We create the framework as follows:
- Let's set up our project. Create a new project, and replace the Scratch cat with a small circle sprite that you...
