Project Aim:

The aim of this project is to create an automatic morning alarm system using simple electronic components.


Components Used:

1.     Power Supply

2.     UM66T (CMOS, Melody Tone Generator)

3.     Transistor NPN

4.     Buzzer

5.     LDR

6.     Resistor 4.7K & 10K

7.     Connecting Wires

 

Circuit Diagram:

 

Connection Procedure:


Step 1: Connect the positive terminal of the power supply (Pin 62) to the collector of the NPN transistor (Pin 31).

Step 2: Connect the emitter of the NPN transistor (Pin 29) to the VDD of the UM66T (Pin 39).

Step 3: Connect the negative terminal of the power supply (Pin 59) to the VSS of the UM66T (Pin 38).

Step 4: Connect the positive terminal of the power supply (Pin 64) to one end of the LDR (Pin 79).

Step 5: Connect the other end of the LDR (Pin 80) to the base of the NPN transistor (Pin 30).

Step 6: Connect the negative terminal of the power supply (Pin 61) to one end of the 10K resistor (Pin 11).

Step 7: Connect the other end of the 10K resistor (Pin 12) to the base of the NPN transistor (Pin 30).

Step 8: Connect the positive terminal of the power supply (Pin 63) to the positive terminal of the buzzer (Pin 54).

Step 9: Connect the negative terminal of the buzzer (Pin 53) to the collector of the NPN transistor (Pin 34).

Step 10: Connect the negative terminal of the power supply to the emitter of the NPN transistor (Pin 32).

Step 11: Connect the base of the NPN transistor (Pin 33) to one end of the 4.7K resistor (Pin 10).

Step 12: Connect the other end of the 4.7K resistor (Pin 9) to the output of the UM66T (Pin 40).

 

 

Explanation:

In this project, we utilize a Light Dependent Resistor (LDR), transistor, CMOS (Complementary Metal-Oxide-Semiconductor), and a buzzer connected in series with other necessary components. When sunlight falls on the LDR, it activates, sending a signal to the base of the transistor. This excites the transistor, turning it into a switch that triggers the CMOS. Once triggered, the CMOS transfers the supply to the second transistor, causing it to conduct and act as a closed switch, which starts the buzzer, producing a musical sound as the output.
