Calculating the battery percentage: - You have to list all voltage regulators and components that are connected directly to the battery - Find out their lowest voltage needed to run (or regulate) properly - The highest low voltage will be a 0% of the battery for you (in this case minVoltage = 6.0V) - The 2 cell Lithium battery has voltage range 6.0V to 8.4V (voltageRange = 2.4V) - Estimate the voltage drop due to current load (voltageDrop = 0.05V) - Formula: percentage = ((batteryVoltage - minVoltage) / (voltageRange - voltageDrop))*100.0f; 0:00 - Introduction 2:02 - Driving around flat 3:49 - Describing Remote App with IP Camera 5:07 - Driving Assistance 6:51 - Drifting with Car 7:53 - Battery Status in Web Browser 8:09 - Explaining Hardware 13:02 - STM32 Configuration 15:30 - STM32 Code Review 31:00 - IP camera with Android 8 31:34 - Android Studio Code Review 36:26 - JavaFX Desktop Application
