a simple voice recognition robot made by a voice recognition robot,arduino uno r3 and l293d motor driver.
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Programme a Voice Recognition Module Via Arduino
record your voices and save them on vr module;
the module,when detects a particular word it lowers the voltage on particular output pin of module.
Step 2: Connect the Output Pins of Module to Input Pins of Arduino.
Step 3: Now Programme the Arduino
i used an arduino uno,programme it in such that if there is any drop of voltage in an input pin,arduino outputs to a corresponding output pin
Step 4: Use a L293d Motor Driver
connect the corresponding output pins to leds and l293 motor driver
