![]() Dataloggers often have to run for several years on one set of batteries so we use smaller Pro-Mini style boards that are more power efficient. The drawback of larger format Arduinosis that they are built for ease of use, rather than being optimized for low power operation. Nothing I’ve used before lets you do classroom demos so easily. This generates a graph live on screen by sending the ‘printed’ numbers over the USB and the graph axes are generated ‘automatically’. The serial plotter built into the IDE makes it possible to view sensor output in real time simply by adding one print statement to the code. The plotter tutorial is probably the most important one in the set for teachers.

We have posted several tutorials for the UNO with the hope that that teachers will use this material as the basis for their own beginner-level lessons. It’s a relatively large board, and robust enough for the physical handling you see in a classroom situation. Most people who are just discovering Arduino start with the UNO. That’s what people new to hardware coding love about Arduino and, that’s what people who know a lot about direct chip programming hate about it. That “hardware abstraction layer” isn’t meant to be the pinnacle of efficiency, but rather to make it as easy to program as possible. Because those low level details are taken care of, you can run essentially the same program on many different flavors of Arduino hardware – even if they look different different physically. The IDE handles a lot of messy details when converting code you’ve written to run on that little chip. ![]() It’s really the integrated development environment (called the IDE) that makes programming the Arduino so easy for beginners. The hardware side of the original Arduino platform is a circuit board built around an Atmel AVR microcontroller with connections broken out so you can physically attach wires to it more easily. ![]() (OR you can jump directly to the latest logger build instructions) THIS PAGE is a consolidated set of links to the different Arduino-based logger tutorials that we’ve released over time, with some commentary to put them in context. A data logger is a device that records sensor information at regular intervals over a period of time so that information can be analyzed to understand phenomenon that are hard to observe directly. ![]()
