Timed Beeper / Zainuddin Wahab and Mohd. Noh Samad

TIMED BEEPER functions as a time controller. So, for this circuit we use oscillator IC for timing function. This long report will show you the function of IC by the timing diagram. Here, we also showed you the logic diagram that is used to show the pin location and their function that create the waveform to get the timer.
To operate this circuit, we used 3v battery and we used Piezo Sounder as their output. We also used Light Emitting Diode that showed the circuit in operation. In this circuit we used other components such as resistors, capacitors, diode, transistor, pushbutton and other components that are related to the circuit.
