Battery Charging

-

hi there,

i designing own board , had design questions adafruit feather mo.
please see schematic: https://cdn-learn.adafruit.com/assets/assets/000/028/801/original/adafruit_products_m0schem.png?1448656357


if usb plugged in , vbus equal 5v no battery plugged in @ vbat. value of vbat pin?

thanks,

d

as read datasheet of mcp73831 @ 4.2v (the termination point cv charging mode); note doesn't matter unless you're using vbat directly, since 3.3v regulator fed vbus if it's connected usb (they put schottky diode vbat input of regulator, , connect directly vbus).

hi new arduino , trying write code of temperature controlled fridge can adjust pot , temp in fridge changes lowest setting -15 , highest setting 30degrees. the temp drops below input pot im trying make compressor turn on , light show compressor on. new @ , im still not quite sure im doing. error below keeps popping , im not quite sure whats wrong code. im hoping on close path how should have done it, how fix error appreciated. arduino: 1.8.4 (windows 10), board: "arduino/genuino uno" c:\users\admin\appdata\local\temp\ccfcxdpc.ltrans0.ltrans.o:(.rodata+0x6): undefined reference `print::write(unsigned char const*, unsigned int)' c:/program files (x86)/arduino/hardware/tools/avr/bin/../lib/gcc/avr/4.9.2/../../../../avr/lib/avr5/crtatmega328p.o:(.init9+0x0): undefined reference `main' collect2.exe: error: ld returned 1 exit status exit status 1 error compiling board arduino/genuino uno. this report have more information with "show verbose output during comp
