Using the male headers the ISD1820 can be easily interfaced with the Arduino. Playing voice message endlessly using Arduino: In the picture above, I am only using the Arduino to power up the ISD1820 Voice Recorder and Playback Module. All you need is the 5 volts power supply. While using the ISD1820 manually, you don’t need the Arduino or any other controller board. You can even use very high power speakers, so far you are able to provide the desired power needed for the speakers. I played the same message again, and this time it was pretty cool. 5w 8-ohm speaker with the external speakers powered up using a 12 volts power supply. 5w 8-ohm speaker is not going to work in real projects, so, before I am going to explain how this module can be automatically controlled using Arduino and sensors, first I replaced the. You need to push and hold the PLAYL button and the message starts playing and if you want to stop the playback at any time, simply release the button.ĭuring the testing, it was hard to hear anything. To play the entire voice message press PLAYE. Now press the record button and start talking. Connect 5 volts and ground from the Arduino or a power supply with the VCC and ground pins. This is the ISD1820 IC, a Microphone, this is where we connect the positive and ground wires of the speaker.Īs you can see the three push buttons and male headers are clearly labeled as REC, PLAYE, PLAYL, VCC, GND, FT, P-L, P-E, and REC.įirst, let’s check how this module can be manually controlled. As per the datasheet, you can select any of these resistors to select a record duration of your choice.īy following this typical schematic you can also make this module by yourself. Currently, the record duration of this module is 10 seconds as this module by default comes with a 100k resistor ROSC. If you want to change the record duration, an external resistor is necessary to select the record duration and sampling frequency, which can range from 8 to 20 seconds. This speaker is good for testing purposes but if you are planning to use this module in a real project then you will need to connect the output of this module to an external amplifier IC like for example LM386. 5W 8-ohm speaker directly without the need for any external amplifier circuit. This module is also provided with an On-chip audio amplifier that can drive a. This voice recorder module is also provided with male headers due to which it can be interfaced with different types of controller modules such as Arduino, STM32, 8051 family of controllers, PIC microcontrollers and so on. The recording time can be changed which I will discuss in a minute.Īs you can see this voice recorder module is provided with push buttons which means you can directly or manually control this module. This voice recorder module comes with a non-volatile storage and playback capability for 8 to 20 seconds. This is the ISD1820 Voice Recorder and Playback Module. I would appreciate your support in this way!Ībout the ISD1820 Voice Recorder and Playback Module: I may make a commission if you buy the components through these links. Without any further delay let’s get started!!! You can record different messages depending on the situation. If it’s a break time you can record a new message, now this time if someone opens the door the break time voice message will be played. The ISD1820 module can be used in offices where you need to play different voice messages, for example when someone opens the door a welcome message is played only one time. When an intruder is detected a voice message is played endlessly. The ISD1820 Voice Recorder and Playback Module can also be used in Security based projects. Like for example, in case if someone ends up in a car accident when a sensor detects a strong hit a pre-recorded voice message is played endlessly. There are situations when you need to play a specific recorded voice message depending on the situation. In this tutorial, we will cover both the manual and automatic control of the ISD1820 Module.
