Optimised for battery life by utilising the ATmega’s power down sleep mode. This extends battery life by many times… I can now run my data logger on a single 9V NiMH battery and keep it topped up with a solar panel.
Any number of analog pins
Any time step
Provides for sensor calibration using a simple linear model (i.e. to convert from analogRead value to whatever you want)
You can download it here. It currently does not handle digital inputs, but this would be easy to change. Please let me know if you use it and/or can think of any improvements. Enjoy!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
