Led Over The Sound Servo Control

Hi there. Im building my first Robot and Im very impressed about the possibilities on the EZ-B.. At this point I really need a help. Im trying to use some leds to lipsync the sound that comes from the sound board (its the robots mouth...). Well, I hooked up the led on a digital port and use the sound servo control... the problem is: the LED NEVER GOES OFF! Even when the value is Zero. And the other problem. It responds to the MIC signal, but not to the soundboard... can someone help me on that ? thank you! best regards from your friends in Brazil.

Hey... Some progress here. In fact, the "trashed servo circuit" trick did work to triger the led... But still only with the sound coming from the mic... I'm sorry... But can you teach me HOW to read only the soundboard sound ? (Not the mic). I tried to turn the "listen" on mic config.. Did not work... Thanks...

Wiring in the LEDs may be an option, though I'd probably need to add a switch in there to control when the LEDs react. Tasty food for thought, Rich.:D

I also was looking for something to drive LEDS like they have on the B-9's chest. From the speaker, not the mic.

Uau! Thanks folks... The easiest solution was the most useful! Just wired the led to the speaker + and - and voila! It blinks sincronized (is this the correct word in english?!?!) to the robots voice! Perfect. I'll post some videos soon. Best regards from Brazil. Tevans.

Glad to here it Tevans. I can't wait to see the videos. I am also interested in this subject. I'm also playing with my first ez-robot kit. I have redesigned it several times. I hope to have my next version completed tomorrow. And yes, that is the correct English word;)

Hi friends, here some pics of the actual stage of my first prototype... I used some plastic trashcans for the body, an candy jar for the head... And built an aluminum frame inside to hold the structure. The hands at this point are made of balsa wood, but I will send the model to get the pieces cuted out in acrylic. The arms are made of plastic and two brass tubes... I am not shure bout the head yet.. But i decided that the bluetooth speaker goes inside that and the leds will be housed in a little box in the mouth.. Well that's it.. It's not a masterpiece, lol... But I'm learning a lot from that. Despite my english...:) Thanks for your help.
