voice recording for raspberry pi 3

$30-250 SGD

Posted about 4 years ago

$30-250 SGD

Paid on delivery
The raspberry pi needs to be able to record and store various different voice signals either via the raspberry pi's storage or through an external storage drive e.g. an SD card. The voice recording should be 5 seconds long. The microphone that's to be used is as attached. A switch or a push button can be use to indicate the start of recording and a timer of 5 seconds is to be implemented to stop the recording. LEDs (e.g. 1 red LED - for recording & 1 green LED - for standby) should also be included to show when the recording is taking place and when it is on standby. Please advise on the hardware for the ADC (MCP3008 10bit ADC with SPI or the ADS1115 16bit ADC with programmable gain amplifier). At the moment, I'm gearing more towards the MCP3008 as it has the SPI interface that memory storage requires. Any further queries or details that is necessary to the completion of this mini project can be given upon request.

Hi I am interested in your offer because of the challenge it means in the integration of the different components they indicate. I am dedicated to projects that are in the industrial area which involve from the creation of the solution, PCB development, programming and assembly. In this I have had to work with Microcontrollers (Microchip, Atmel, Arduino, ESP32), embedded systems (raspberry pi, owasys, onion Omega) in the collection of data with sensors of all kinds from environmental to Physical as well as the control of devices ( pumps, actuators, etc.) according to certain conditions or actions. In addition to collecting the information (creating the communication protocol or implementing it) either through RS232, RS485, USB, RF, WiFi or bluetooth, and send it to the cloud via GPRS or LAN for analysis in a DashBoard. I have been developing solutions with these devices for more than 10 years. But I would like to have more details of the project to be able to define price and time in a better way. regards Claudio Zeiss Martinez
