The user will be able to learn how to control a robot using sound and gesture technology. In the sound section, the user will be able to learn clap based switching control using sound sensor, timer and decade counter. In the gesture section, the project explains the use of motion sensor like accelerometer , Arduino based ATmega328P microcontroller, RF based wireless control, encoder and encoder techniques.
Product Description
This is a 2-in-1 project to control the robot in four directions (forward, backward, right and left) either by clapping or hand gesture. A switch is used to change the mode of operation from clap to gesture control.
The main components in clap circuit includes LM741/NE5534 op-amp, NE555 timer, 4017B decade counter, L293D motor driver, an electret microphone and some few components. The sound of each clap is captured by the electret microphone which is used as sound sensor.
When it is in clap mode, each clap acts as a control signal to move the robot in either forward, backward, left or right direction. The fifth clap is to stop the robot.
Gesture control system consists of transmitter and receiver units. Transmitter unit should be in your hand and receiver unit should be attached to the chassis of the robot. The robot will move in the direction (forward, backward, right or left) as per the position of the transmitter unit in your hand.
The main components in transmitter unit consists of ATmega328P microcontroller, ADXL335 accelerometer, HT12E encoder and 433MHz RF transmitter module whereas the receiver unit consists of 433MHz RF receiver module, HT12D decoder and L293D motor driver
