![]() Another challenge is that other USB devices can push the bus too fast for the slow serial UARTS, causing them to drop off the system due to timing conflicts. A ‘breadboard logger’ like the one shown later in this post lets you do that testing quickly. One big challenge of running a course remotely is the extra time to test all the parts before sending them out. Even that will be challenging through a zoom window, so you might want to add USB isolators to protect tethered student laptops from accidental shorts. The complete tutorial can be run in person or if students are ‘distance learning’, the instructor can do the soldering (~15-20 minutes per set) and send out kits for the overall assembly. All connections are made by Dupont connectors or by clamping wires under screw terminals. With that in mind, we’ve divided the build tutorial from 2019 into separate stages that make it easier to restructure the labs:ġ) Component prep: requires the equipment you normally have access to in the lab like soldering irons, heat guns, drills, etc.Ģ) Logger assembly: can be done remotely with scissors, wire strippers & a screwdriver. ![]() This is a combination of inexpensive pre-made modules from the open-source Arduino ecosystem, and can usually be assembled by beginners in 1-2 hours.Ĭovid has thrown a spanner into the works for hands-on learning because even if you have the space to run a ‘socially distanced’ course, your students could still be sent home at any time. 2020 update to the Cave Pearl Classroom logger.
