Design and implementation of a prototype lamp for an Arduino nano-based disaster situation, consisting of a buck converter circuit with Arduino Nano as a Pulse Width Modulation duty cycle regulator with voltage sensor feedback and current sensor. The voltage from the 30 Wp solar panel will be set by the MOSFET as switching at high frequency with the PWM method from the Arduino Nano. The buck converter circuit is an inverting type because it has a position that is reversed from the supply voltage. In this study, the load used was a 3.7 V 17,000 mAh lithium battery. The estimation of the battery charging process takes ± 5 hours with a current coming out of the solar panel of 0.45 mA in the hot sun. The load to be used is the Joule Thief circuit (prototype lamp). The Joule Thief is a small, low cost and easy to manufacture minimalist self oscillating voltage amplifier used to drive small loads such as led lamps or DC dynamos. This circuit is able to work ±14 hours running led lights with a power of 5 watts 220 Vac with a battery capacity of 17,000 mAh.
