• Arduino UNO
• DC Motor
• Mobile Phone
• DTMF decoder Module
• Motor Driver L293D
• Battery Connector
• Aux wire
• Robot Chasis with wheel
• Connecting wires

Features:

• Remote section: This section’s main component is DTMF
• Here we get a tone from our cellphone by using aux wire to DTMF Decoder IC namely MT8870 which decodes the tone into digital signal of 4bit
• Control Section: Arduino UNO is used for controlling whole the process of robot
• Arduino reads commands sent by DTMF Decoder and compare with define code or pattern
• If commands are match arduino sends respective command to driver section
• Driver section: driver section consists motor driver and two DC motors
• Motor driver is used for driving motors because arduino does not supply enough voltage and current to motor
• So we add a motor driver circuit to get enough voltage and current for motor
• By collecting commands from arduino motor driver drive motor according to commands
