This post explains how to use built-in ADC feature of AVR Microcontrollers. ATMEGA8 is used in this example, along with the source code in C. As you all know, natural environment is all analog. From temperature to seismic waves and from wind to fire every value is continuous in nature. But the problem is that all electronics is turning into digital, a non-continuous domain. So to acquire data from the environment we use an ADC (Analog to Digital Convertor). Continue reading

Scientists at the university of California have managed to implant a chip in a giant flower beetle that makes it respond to commands from the computer. They can tell it to fly, stop, turn left and turn right. The controls are done through its optic nerves and wing muscles. Though the article states that flight signals are sent to the optic lobes and steering is done through stimulation of the wing muscles, the video shows steering being accomplished through optic lobe stimulation.
