Arduino CO Monitor Using MQ-7 Sensor : 8 Steps (with Pictures ...

Warning: this affects Arduino's main timing interrupt, so all time-dependent functions (like millis() ) won't produce correct results in this sketch (more on this later). Pin D3 has hardware Timer2 output connected to it (as well as D11 - but it's less convenient to put wire on D11 than on D3) - so we are using it to provide PWM for voltage controlling transistor. Resistor R1 is used to control brightness of LEDs. It …
