V-USB

V-USB is a software-only implementation of a low-speed USB device for Atmel’s AVR® microcontrollers, making it possible to build USB hardware with almost any AVR® microcontroller, not requiring any additional chip.

BEAM Robotics

BEAM (Biology Electronics Aesthetics and Mechanics) Robotics , it is an approach to robotics using simple analog circuits rather than using micro-processors or micro-controllers. This concept uses a type of circuit configuration which mainly consists of a neural network referred as "Nervous Net" or "Nv Net" whose element are none other than artificial neurons.

Why??
Reduce the cost and complexity of the design. It takes less time to build a Beam-Robot rather than designing traditional machines, also the size of Beam Robots are smaller than traditional robots.

Nv Neuron ???
Artificial neurons are made of a resistor, capacitor and a NOT gate.

ATmega32's Internal EEPROM

The EEPROM is an area of read/write memory that is non-volatile i.e., the stored data is not lost even if you power off the device.

The ATmega32 has a inbuilt EEPROM in it . Before starting to learn about using the internal EEPROM, let's get to know about the risk's that involve in using a Internal EEPROM.

1. Internal EEPROM might get corrupted while the power is being switched off.
2. Supply voltages are likely to rise or fall slowly during power up or down, this causes the device to operate at a voltage lower than the specified minimums voltage for the clock frequency used. This might lead to an unintentional write of the EEPROM.

PWM with ATMEGA 32

PWM - Pulse Width Modulation.

The basics about PWM can be read here

Why PWM??
Suppose you have a motor with a certain torque and RPM, and you want to change the RPM. This can be done easily by reducing the voltage supplied, but due to this even the torque of the motor reduces. So, how to control the RPM of the motor without compromising on torque ???
The answer is PWM - Pulse Width Modulation
