Hello, good time
Project equipment:
1- Bread board
2- Arduino Nano CH340
3- Carbon monoxide detection sensor module MQ-7
4- 7segment of four digits TM1637
5- 5 volt Buzzer
6- Connection wires
7- Red and Green LED
8- Arduino Nano interface cable
The carbon monoxide project is such that if the amount of carbon monoxide is more than 60, it will be displayed in 7segments and the red LED will light up and the Buzzer will sound.
But if the amount of carbon monoxide is less than 60, only the green LED will light up.
