Abstract — Stable bioethanol stove operation requires coordinated temperature acquisition and fuel delivery. This study presents an Arduino Nano control platform for a wickless stove. Two K-type thermocouples are digitized by independent MAX6675 modules and averaged every 2 s. A 4×4 keypad and 20×4 I2C LCD provide input and status, while D11 supplies PWM through an L298N driver to a 12 V pump. Thermocouple tests from 100 to 200 °C produced 1.63% mean error. L298N tests at PWM 140–160 produced 2.00% mean voltage error. Sixteen-point pump calibration increased flow from 0.045 to 0.964 mL/s and yielded Q = 0.012574(PWM) − 1.3794 with R² = 0.9585. The results verify the embedded sensing and fuel-flow actuation chain
