It uses DC5V voltage to work. When you press the different keys, the loudspeaker will sound that which floor you arrive. This design uses a APR voice chip as the core of the circuit and realizes the function of auto recording and playback. It uses power amplifier chip JRCD to amplify the audio and enhance the volume. The voice recording and playback circuit is widely used in everyday life.

For example, the leaving message and response of the telephone, game machine, and toy voice recording and playback, telling time of the clock or alarm, selling products and control of the household appliance, etc.

The designed circuit control is easy ,high-quality sound and big volume. It can be recorded and played for many times and has strong ability of portability. It can be used in other ares for a little modification. The voice recording and playback using the APR chip as the core has the advantage on the price. It is worth of promoting. Full Project: Functions: 1. When you press the key NO. When you press the NO. At the same time, connect the pin2 and pin4 of JRC power amplifier chip to the ground.

Step 3: The connection of the capaciptor C1,C9,C11 1. The connection of the capaciptor C1 According to the schematic diagram, put the 0. Connect the pin6 of JRCD power amplifier chip to the anode of the power supply. The connection of the capaciptor C11 Put the 0. Then the other end connect to the anode of the power supply 4. And then connect the 10uF capacitor C9 and 0.

Step 4: Connection of capacitor 15 , 13 1. Connection of capacitor 15 According to the schematic diagram, put the 47nF capacitor C15 and 10K resistor R20 to the bread board. And connect the other end of 47nF capacitor to the ground. Connection of capacitor 13 Put the uF capacitor C13, and make one end of it connect the resistor R Step 5: The soldering and connection of speaklouder The soldering of the speaklouder.

The anode solers to the blue wire and cathode solders to the gray line. Connect the anode of the speaklouder which is soldered well to the uF capacitor C13, and connect the cathode to the ground. And then plug into the the GND of power supply line. And then plug into the other end of connecting line about the 0. The pin11 of APR voice chip to connect the anode of power supply. Pin 12 and pin13 of APR voice chip to the ground.

Step 8: The connection of resistor R4,R2, 1. The connection of resistor R4 According to the schematic diagram, put the 43K resistor R4.

One end to connect the pin7 of APR voice chip and the other ground. Connect The pin26 APR voice chip to the ground. Step 9: The connection of Pin28 APR voice chip and C10 and C11 two capacitors According to the schematic diagram According toe the schematic diagram, put two pins of the 0.

And make the pin28 of APR voice chip connect the other end of he C10 and C11 these two capacitors and then connect the anode of power supply. Step Put into the 0. Step The connection of capacitor C3, resistor R5 and capacitor C14,15 1. The connection of 4. And connect one end of these two products in parallel to pin19 of the APR voice chip.

And connect the other end to the ground. The connection of 0. And connect one end of these two products in parallel to pin15 of the APR voice chip. Put into the resistor R0 According to the schematic diagram, put the 0.

Put the 4. Connect one end to the o. Put into the resistor R6 Put the 4. Put into the resistor R7 Put 1K resistor R7 into the bread board and make one end connect the 4. The other end connect the anode of the power supply. Put into the resistor R1 According to the schematic diagram, put the K resistor R1 on the bread board and make one end connect pin23 of APR voice chip. And then connect another end to the ground. Put into the resistor C5 Put the 47uF capacitor C5 into the bread board.

And make one end connect the 4. Put into the resistor electret microphone Put the electret microphone to the bread board. And make both ends of it to connect 0. Step Put switch S9 into the bread board According to the schematic diagram, put the switch S9 into the breadboard. Make one end of it connect the pin23 of voice chip APR And connect the other end to the anode of power supply. Step Connect the pins of APR to the dials of dip switch According to the schematic diagram , put the Dip swith into the bread board.

Connect 4 legs of one end of the dip switch to the ground. And the other end of 4 legs connect the K resistor, also the anode of power supply. Connect the pin27 of APR to the No. Connect the pin24 of APR to the No. Connect the pin25 of APR to the No. Connect the pin9 of APR to the No. And then connect the 8 switches to the ground. According to the schematic diagram, connect the 0. And the blue bread wire as the power supply and white bread wire as the ground line.

Step Video to show the actual effect.
