Robotic eye response,a pair, to audio input

Sensors Sound & Audio
1

Project name: Hug Monster, Frank Hodgson

two parallel, level audio mikes; spaced apart about 1/2 inch on forehead of doll-like unit

sound source; noise or speech, about 15 inches away

lateral offset (of pair of eyes); due to time of delivery difference; about 40 deg (right or left), zero if no difference

slow response time; eyes and eye support frame are light weight

possible use of 2 Arduino microphone sound input modules

-/-/-

suggestions as to gear to process input and drive eye frame requested

Thank you. Frank

Hi Frank, and thanks for posting.

For moving the eyes, you might consider a servo like one of the ones below.

  • - [[Servo - Hitec HS-85MG](https://www.sparkfun.com/products/11887)
  • - [[Servo - Hitec HS-425BB](https://www.sparkfun.com/products/11883)
  • - [[Servo - Generic](https://www.sparkfun.com/products/9065)
    • [/list]

    Any of those can move the eyes left, right or straight ahead.

    For sound input, our [Sound Detector board might work for you and for a controller that receives input and controls the servo, our [RedBoard Qwiic could be used.

    You’d need to write the software that makes everything function the way you’re looking for, but these parts should do the trick. :-)](SparkFun RedBoard Qwiic - DEV-15123 - SparkFun Electronics)](SparkFun Sound Detector (with Headers) - SEN-14262 - SparkFun Electronics)](Servo - Generic (Sub-Micro Size) - ROB-09065 - SparkFun Electronics)](Servo - Hitec HS-425BB (Standard Size) - ROB-11883 - SparkFun Electronics)](Servo - Hitec HS-85MG (Micro Size) - ROB-11887 - SparkFun Electronics)

    Chris - Many thanks. I’ll do my homework. Frank
