Cell Phone Controlled Robot using 8051 Microcontroller


This project involves building a cell phone controlled robot using an 8051 microcontroller, utilizing mobile DTMF technology for precise control through DTMF tones generated by specific frequency combinations.

Project Information

In this intriguing project, we delve into the construction of a cell phone controlled robot using the versatile 8051 microcontroller, with the robot’s movements governed by mobile DTMF (Dual Tone Multiple Frequency) technology. By combining and manipulating specific frequencies, we create DTMF tones, which serve as the foundation for controlling the robot through a cell phone interface.
