The controller makes use of controllers; Depending on the They indicate that DC motors can be rotated. With the help of mobile keyboards operations It will be done. Also a mobile phone that will operate the directions and speed of the boat Based on DTMF technology. DTMF (Dual Tone Frequency) depends on the The keyboard emits tones in which each tone can generate a certain frequency depending on which, The boat will operate and increase or decrease speed. This project uses two DC motors respectively. The DC motor generates torque Directly from the DC supply supplied to the motor by internal switching, Permanent magnets and rotating electric magnets. Advantages of a brushed DC motor.They include low initial cost, high reliability and simple engine speed control. The disadvantages are high maintenance and low life for high intensity applications. Driver Used for DC Motors is L293D. This microcontroller is able to communicate with inputs and outputs Modules. The microcontroller interconnected with the DTMF decoder is used to Address of the boat. LED indicator indicating that the motor is on / off in case of addresses. The mobile phone acts as a remote control.
