Here is an easy tutorial how to make simple voltage monitor with sample code http://www.instructables.com/id/Arduino-Voltmeter/ And code for status led just reads the value from analog input so you can set up different thresholds and light up an LED if (analogRead(A0) < 624) { digitalWrite(Pin_LED,...

Thank you banjo! Than we need for a blue LED a 90Ω resistor and for the red LED a 150Ω resistor. Can you please explain us how we can monitor the current battery capacity and output this via the LEDs?(e.g. red LED=critical battery status) A code sample and a wiring diagram could be helpful. Thanks ...

If I am right you don't need so big resistors. Of course it depends on which LED you want to use. Here is how I understood it: The LEDs on the Home bord PCB get their power from the Teensy. The Teensy outpouts 5V. So if you use Ohm's Law then you get this: For a blue LED with 3,2 V and 30mA: R=U/I R...

@banjokazooie I think Misturbubles speaks about the capacity (Ohm) of the resistors. In your M5 built you use 0805 SMD's and the capasity was 270 Ohm. How did you read the battery capacity in your M5 built and display it via the LED's on the Home PCB? I've already built and soldered most of the part...

Which kind of LED colors did you solder on the Home board and in which order? Because the original Wii U homeboard has only two diferent LEDs. A red one to show you the battery capacity, which is either blinking or steady or off, and a blue one for the "Home" button. If I read the pi_power project o...

@CJnyc3 or banjokazooie I 've ordered the Wii u PCB board to. Thank you very much for the board. It makes the work much more easier. I have a question: In witch way do I have to solder the SMD LEDs on the PCB? I mean where is the anode and the cathode on the board? Thanks a lot Sorry for my bad engl...
