This project is designed for Animatronics and Puppeteer applications, however, it can be used in other applications like sound responsive toys, robots, etc. Especially this project helps to move the jaw or mouth of an animatronic creature.
The project moves RC servo once receives any kind of sound. The rotation angle depends on the sound level, more the sound level more the movement. The movement of the servo is proportional to the sound level.
The circuit has 4 channel servo drivers, the First channel is driven by sound, and rest 3 RC servos controlled by the onboard trimmer potentiometer, these 3 channels helps to drive other movements of the animatronics figure.
Sound Received by the microphone is converted to DC voltage, PIC16F72 microcontroller converts DC voltage into the RC PWM signal. The circuit works with 5V DC and it is advisable to use a battery for low jitter.

Hi there, Thank you for the information. Where can I get this board? Is sold somewhere?
2 years agoHi, it is not sold, but we can manufacture it for you if order is >25 pieces. If you are interested use the contact us form.
2 years agoYes let me know the cost for 24 pieces
1 year agocan you still produce these boards?
11 months agoYes, we can produce this in order. Please contact us from the contact-us section of the website.
11 months agoWill this board work with an external input. Say direct input from a sound source like a 3.5mm jack playing a voice? Also, correct me if I’m wrong but the other 3 channels could be used if say you have a mouth using 2 servo’s (one on each side of jaw) …Am I correct? Let me know as we would be willing to build one..just need to understand a bit more.
2 years agoHi how much to have 25 of these units to be made.
12 months agocheck your email.
12 months agoHi, I am interested in buying 2 or 3 of these boards . Can you please tell me a price ?
10 months agocheck your email, please!
10 months agoHi, I am interested in buying one of these boards. can you tell me a price
5 months agoHow much would it cost to buy 5 of these boards (pre-assembled and ready o go?)
3 months agocheck your email, please!
3 months agoDo you also happen to have the CPL file for this?
3 months agoWhat do you mean with CPL file ?
3 months agoHello, can someone help lease. i’ve created the cicuit it turns etc. but do not work. no reaction to sound or movement usin potentiometer.
3 months agoHave you programmed the MCU successfully?
