Abstract
Some embodiments provide a system that facilitates use of an electronic device. The electronic device may be a keyboard, a mouse, a trackpad, a remote control, a wireless phone, a toy, a battery charger, and/or a camera. During operation, the system measures a loaded voltage of a calibrated voltage source connected to the electronic device. To measure the loaded voltage, the calibrated voltage source is connected to a known load in the electronic device, and a voltage measurement for the calibrated voltage source is obtained using an analog-to-digital converter (ADC) in the electronic device.
