Low Cost Internet Enabled Voltage and Current Logger with @AdafruitIO #AdafruitIO #IoT
Darian Johnson “needed a low cost way to measure current requirements and battery drain over time” for one of his wearable projects. He also had a “TON of Adafruit Feathers and FeatherWings, so [he] decided to use components [he] already had, plus an Adafruit INA219 FeatherWing to build a voltage and current logger.
Not only does the logger he built have an onboard graphical display for displaying the current/voltage at a specific time – it can log to Adafruit IO and a SD card.

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
