A password-based circuit breaker or PBCB is an electrical switch operated through a user-defined password, providing a secure and controlled means of activating or deactivating an electronic circuit.

Coming to Arduino (Uno), the PWM frequency at Pin 9 is close to 500 Hz, and with fc = 500 Hz, the period is 1/fc = ~2 ms. Note that the statement “analogWrite( PWM_ pin, level);” sets the PWM _pin to ...

The 16×2 LCD unit is directly connected to the Arduino Uno board in 4-bit mode. Data pins of the LCD, namely RS, EN, D4, D5, D6, D7, are connected to Arduino digital pins D7, D6, D5, D4, D3, D2. The ...
