Lecture
This lecture covers the testing and charging of batteries using microcontrollers. Topics include measuring battery voltage, charging and discharging processes, setting up a microcontroller circuit, programming for voltage measurement, and managing charging and discharging currents. The lecture also discusses keyboard command management, faster charging and discharging with transistor circuits, voltage measurement techniques, calculating internal resistance, and possible enhancements like end-of-charge detection and trickle charging.
