Arduino Gas Level Indicator using MQ2 Sensor & LED Bar Graph 🔥⚡ #arduino #mq2 #electronics #diy
This project uses an MQ2 gas sensor to detect gas levels and display them using multiple LEDs as a bar graph. When gas from a lighter is detected, the sensor sends analog values to the Arduino. Based on gas intensity, LEDs glow one by one, indicating the gas level in real-time. Higher gas concentration → More LEDs glow ⚡ 🧰 Components ...
