Souce Code formatter for blogger

Here are some sites that help you to convert your code snippets into html format. The code is converted into a tabular format.

Interfacing HC-SR04 Ultrasonic Module with Arduino Pro Mini

SR04 is a module that can detect distance between 2cm to 400cm by sending out ultrasonic waves and calculating the time between the sent signal and echo received.


Steps:
  1. Send the trigger signal - a TTL 10us signal
  2. Wait for the echo pin to get high.
  3. Calculate the time for which the echo pin is high using a timer.
  4. Calculate the distance using 
Distance = high level time * velocity (340M/S) / 2

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.
