Build a Lithium-Ion Battery Charger on Arduino | μF

The Lithium-Ion battery is connected across the B+ and B-terminals. The battery charging current is regulated by switching P-Channel MOSFET (field-effect transistor) Q1 via pulse-width modulation (PWM). The PWM-enabled digital output pin 9 on the Arduino generates a PWM signal which drives the gate of the MOSFET Q1 through the NPN transistor Q2.
