Buzzer Interfacing With 8051 With C
Buzzer is a electronic device that converts the electronic signal into buzzing noise, that is applied to it. It can be used as electronic.
FunctionThis project shows how to interface a buzzer to the microcontroller. When a push button has pressed a buzzer will on and off 30 times and then stops. Pramukh gujarati font converter. Components. AT89C2051 microcontroller. Push button switch. Buzzer.
Capacitors: 33pF,33pF,10uF. Resistor 8.2KOCircuit diagramA circuit diagram for interfacing buzzer to the microcontroller is shown in the figure below. Bit 7 of port 1 is directly connected to a small buzzer. This type of connection is possible only when the current required for the buzzer is less than 20mA. The port output is in current source mode so that the buzzer will turn on when the output is at logic LOW.
Bit 0 of port 3 is connected to the push button switch which is held at a logic high by the pull-up resistor. Simple buzzer interface Program descriptionThe buzzer is initially OFF. When the push button is pressed, the buzzer is turned ON and OFF 30 times, with a one second delay between each output.
