Arduino Bluetooth Control Robot designed with Speech recognition increasing the ability to interact with the human in a natural form of communication. This is undergone through android application locally available and Bluetooth module. The app converts the command from the human into text and then delivers to the Bluetooth module.
The command for the robot given by the human through an Andriod application. The app converts the human voice into a text as characters. These characters receive from the Bluetooth connection with Arduino and these stored as strings. The pre-programmed words already present in the Arduino. The text received through the Bluetooth matches with the preset words then, the robots work according to that command. The command from the Arduino sent to Motor driver then the drives send current to the particular motor.
- Bluetooth Module has RX, TX, Supply, and Ground.
- RX connect with Arduino as TX.
- TX connect with Arduino as RX.
- GND connect to Ground.
- +5 V connect with the supply.
If you two motors, two input pins assigned to rotate the motor. If you are using four motors, four input pin link with Arduino.
Connect the Motor terminals with the Motor driver. If you want to use 2 motors, L298N is good.
L298N is a dual H-bridge Motor driver IC. This is an integrated monolithic circuit during a 15- lead Multiwatt and PowerSO20 packages. It’s a high voltage, high current twin full-bridge driver designed to simply accept commonplace TTL logic level sand drive inductive masses like relays, solenoids, DC and stepping motors. 2 modify inputs area unit provided to modify or disable the device severally of the input signals. The emitters of the lower transistors of every bridge area unit connected along and the corresponding external terminal will be used for the affiliation of associate external sensing electrical device.
Two built-in H-bridge, high voltage, large current, full bridge driver, which can be used to drive DC motors, stepper motors, relay coils and other inductive loads. Designed using standard logic level signal to control. This module capable to drive a two-phase stepper motor or four-phase stepper motor, and two-phase DC motors.
