Have you ever wanted to monitor how much voltage/current your small PV solar panels are producing? It is easy enough with a multi-meter, but what if you just want to monitor it remotely and log the data on your computer. This high level overview shows a xbee setup remotely logging a PV panels volts/amps to a mac laptop. It makes use of only 10 ohm resistor and 2 ADC ports. No additional microcontrollers were necessary for this example. The PV solar panel is made by Voltaic Systems and costs only $30 (it peaks at 10.2V @ .133A)
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.
