Cell Phone Controlled Robot using 8051 Microcontroller In this project we are going to build a cell phone controlled robot using 8051 microcontroller. Cell phone controlled robot runs over mobile DTMF technology. DTMF stands for Dual Tone Multiple Frequency. There are some frequencies that we use to create DTMF tones. In simple words by adding or mixing two or more frequencies we generate DTMF tone. These… |

Edge Avoiding Robot Using 8051 An edge avoider robot is quite similar to my previous project "Line Follower Robot". This 8051 microcontroller based robot detects an edge and avoids it by turning or stopping. Let us see how can we design a edge avoider robot easily. Concept of Edge Avoider Robot Concept of Edge Avoider robot is same as line… |

Line Follower Robot using 8051 Microcontroller Line follower Robot is a machine which follows a line, it may be a black line or a white line. Basically two types of line follower robots are: one is black line follower which follows black line and second one is white line follower which follows white line. Line follower actually senses the line and run over it. In our previous projects, we have made a black line… |

GSM Module Interfacing with 8051 Microcontroller GSM module is used in many communication devices which are based on GSM (Global System for Mobile Communications) technology. It is used to interact with GSM network using a computer. GSM module only understands AT commands, and can respond accordingly. The most basic command is “AT”, if GSM respond OK then it is working good otherwise it respond with “ERROR”. There are… |

Stepper Motor Interfacing with 8051 Microcontroller A stepper motor is a brushless DC motor, which can be rotated in small angles; these angles are called steps. Generally, a stepper motor interfacing with 8051 uses 200 steps to complete a 360-degree rotation, which means it rotates 1.8 degrees per step. Stepper motor control using 8051 microcontroller is used in many devices which need precise rotational movement, like… |
