Gas Detection Alarm

We will build a gas detector below that will sound an alarm if it detects a gas leak. The alarm will sound until the gas leak is stopped. In addition, LEDs are triggered depending on the amount of gas that the sensor detects. If there is a lot of gas leaking, all four LEDs should light up; if there is little gas, only one of the four LEDs should light up
