Introduction: Arduino MQ-2 Smoke and Gas Sensitive Security Alarm
මෙහි දැක්වෙන්නේ Gas හා දුමට සංවේදී Security Alarm එකකි.
මෙය Arduino හා MQ-2 Smoke and Gas sensor යොදාගෙන නිර්මාණය කර ඇත.
Step 1: අවශ්ය කරන දෑ
1. 1x MQ-2 Smoke and Gas sensor
2. 1x Arduino board ( Arduino Uno, Mega, pro mini, nano)
3. 2x Red and Green led
4. 1x Bread board
5. Jumper cables
6. 1x 5v Buzzer
