When reed switch is opened, pin 2 of Arduino goes high with the help of the pull-up resistor R2, and the alert signal is available through the piezo-speaker PZ1 (not an active piezo-buzzer). At the ...

It is built around Arduino Uno board (board1), seven LEDs (LED1 through LED7), three tactile switches (S1 through S3) and a few discrete components. Fig. 2: Circuit diagram of the window alarm ...

As shown in figure, an Arduino UNO has 6PWM channels, so we can get PWM (variable voltage) at any of these six pins. In this chapter we are going to use PIN3 as PWM output. Required Components.
