Help with guard bot please check out c if u can help

i want my robot to roam until it hears something with a mic sensor then stops. howd i do this i have it roaming and i used the mic sensor on a sepertatly coded arduino!

An even cheaper Wi-Fi board


For a few cents more than the ESP12F you get it with a programmer daughter board, a RGB led, a button and a photoresistor.
This is ideal for small robot with networking abilities.
Can be programmed with Arduino IDE as a NodeMCU v1.0 .

An accelerometer/gyro goes onto an Arduino board and transmits the angular motion of the board via bluetooth to a (extremely amateur VR game) I made in Unity for Android phones.
This is a really fun and easy project that can be done in about an hour. On the bottom of the skateboard is an accelerometer/gyro with an Arduino board that … Read more

Curt the Creeper Update: Adding Voice Interactivity and Sound; 4 bar linkage design

Update:
--------------

I spent the past few weeks researching voice interactivity and sound effect playback (mainly through Google search), and designing a 4 bar linkage to figure out what powertrain I need to drive the feet movement.  I thought others might benefit from info about my work so I'm posting it here.  This project will likely move at a fairly slow pace mainly due to current budget constraints.

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
