Winter the Street lights are switched ON at the same time in the evening around 6:30 pm and switched OFF at around 6:00 am. And we know that it will be more sunny in summer season with enough light up to 7.00 pm and from 5 pm. So unnecessarily the power is wasted during these times over a period of a particular season. So a idea is proposed to design a Control system with automation. The designed system will overcome all the above said problems. This project gives the best solution for electrical

the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs)‚ 6 analog inputs‚ a 16 MHz ceramic resonator‚ a USB connection‚ a power jack‚ an ICSP header‚ and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead‚

that their tips rest on metal pads on the wafer. Care must be taken while manipulating the probes to avoid damaging the probe tips or the devices under test. The probes and wires used in the 4752 lab are suitable for relatively low-frequency and low-power measurements. The general procedure for testing a device involves connecting suitable test equipment to probes using the banana-plug wires‚ landing probes on the appropriate metal pads using the microscope and probe positioners‚ and performing the

CHAPTER 1: AIM The aim of this project is to copy the hand and arm motions of a human operator and repeat the same motions on a human like robotic arm system‚ simultaneously. Introduction A robot is an automatic or virtually intelligent agent that can carry out tasks robotically or with some supervision‚ typically with the aid of a remote control. In practice‚ a robot is usually an electro-mechanical machine that is guided by means of computer and electronic

Make a Simple RC (Remote Controlled) Robot Car Whether you are an engineering student building a multi terrain vehicle or an electronics hobbyist trying to impress people with your skills‚ Making a RC robot car (wireless) is much better than the wired robot which you will have to tail while driving. Here is a simple‚ yet informative post for beginners in the field of robotics. Mind you‚ this not robotics. This is just a toy with which you can play around and still get a hold of the basic concepts
