Cell phone operated Robot is a Robot whose movement can be controlled by pressing the number of cell phone. The robot can move forward, backward, right or left which depends on the numbers you are pressing. The property of Robot to operate by the cell phone helps you to operate the robot from some distance.The Cell Phone controlled Robot uses DTMF (Dual tone-multi frequency) module. It is capable of receiving a set of command (instructions) in the form of DTMF (Dual tone multiple frequency) tones and performs the necessary actions.

Audio is one of the most common media. Here, It refers to the representation of sound which can be perceived by humans. Audio and Video are the essential component of any electronic media. The electronics can be used to receive audio signals (via microphone), record audio in some storage, transmit audio (through wired or wireless communication channels) and reproduce audio signals (via speakers). The audio can be represented and transmitted as either analog signals or digital signals. In this series, analog audio signals are the concern. The audio signals have a frequency range of 20 Hz to 20,000 Hz.

SPI protocol has earned a solid role in embedded systems whether it is system on chip processors, both with higher end 32-bit processors such as those using ARM, MIC or Power PC and with other microcontrollers such as the AVR, PIC etc. These chips usually include SPI controllers capable of running in either master or slave mode. In-system programmable AVR controllers can be programmed using an SPI interface.Chip or FPGA based designs sometimes use SPI to communicate.So, SPI is a common technology used nowadays for communication with peripheral devices where we want to transfer data speedily and with in real time constraints. There are many serial interfaces right from Morse code telegraphy, RS232, USB, Fire wire, Ethernet and many more. Each serial interface offers advantages or disadvantages for many designs,depending on criteria such as needed data rate, space availability, and noise considerations.

In this tutorial, we’ll learn how to interface the four-in-one BME680 pressure, gas, humidity, and temperature sensor with Raspberry Pi (RPi). This will include understanding how to log and retrieve data from a database. The BME680 can “communicate” with external controllers on either the serial peripheral interface (SPI) and I2C protocols. For this project, we’ll…

Much like the name suggests, DC motor controllers control the speed and direction of a DC motor. To change the direction of the motor, however, the supply it receives must be reversed. And, to vary the DC motor speed, a pulse-width modulation (PWM) signal or wave must be applied to it. As the pulse width…
