Arduino sketch, which helps detecting the connections of the I2C interface and prints info available from the SMB (SmartBatteryModule) laptop battery pack.
This will change life of your laptop's battery This app will notify the user to remove the charger when his battery will be fully charged or is about to die.
Intro: long time i was harvesting lithium ion batteries from scrap laptop battery packs it's wasn't easy to test battery capacity manually so i made this device to tell me the output volt and current of the battery and calculate the battery capacity and life time Used components : display used in this project 1602 LCD with shift register 74ch595 to save atmega328 pins also there is i2c port on the pcb for who wants to add any i2c module but you have to edit the code to fit your needs for charge and discharge i'm using TIP41C isolated by opto coupler inquick test mode the circuit using 2 1 ohms resistors 1 as shunt and the other as load in charge mode using 1 ohm resistor as shunt for current measuring

This is a battery percentage notifier using python. It currently supports Windows, linux, android, ios and macos. It generates a message that shows you the percentage of your remaining battery.
It's possible make the icon in the taskbar show the actual battery percentage, and makes this icon bigger that i want?
