Arduino for the control of models of trains and layouts. Trains are moving by simply apply voltage to the rails, the loco speed change use PWM method. It's classical DC system – no DCC, no decoders. This is a plain and clear system. You can even use the URB project for educational purposes. Smart signals and tracks indication.

/7/2016I have an mcp73833 board which i connected to the battery(3. 7v 2200mah) forever, and it is running the arduino mega. Is there any indication of discharging to send to arduino so that arduino can open relay to the charging connection to charge the battery withaout actual power off the arduino?

VIN. The input voltage to the Arduino board when it’s using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin. 5V. This pin outputs a regulated 5V from the regulator on the board.

Phase Smart Energy Meter using Arduino. A LED is present here for the indication whether the Smart Energy Meter is Powered ON or OFF. Then a diode is used to rectify the negative part of the voltage. ADC of Arduino is only rated for voltages between 0 and +5V DC on any input pin.

Arduino voltage indication


Several times I've wished I had a battery indicator in my battery-powered projects, but it uses so many custom characters in the LCD and sacrifice analog input for voltage indication and components and connections. So we decided to do it the smart way and push the Arduino to its limits and get the maximum out of it.
