Generating time delay using astable mode of 555 timer IC
This circuit based project demonstrates the working of 555 timer in astable mode to generate pulses of time period 0.5 second. This pulse can be further used [[wysiwyg_imageupload::]]for anything where we need a pulse such as to blink a LED or to create fashionable blinking lights. This circuit of this project makes the use of timer IC NE555 which produces a constant square pulse of a desired frequency. This pulse could be either triggered or could be produced continuously depending upon the mode of 555 we are using. The two mostly used modes of 555 are Monostable and Astable. Here it is used in the astable mode with time period of half second, with high time period of 0.333 seconds and low time period of 0.166 seconds. Keep on reading to find out how the circuit is constructed and in what mode does the 555 IC works.
Light dependent frequency variation using LDR
This circuit responds to the change in light illumination in the form of varying frequency which can be observed through a flashing LED as output. The idea of [[wysiwyg_imageupload::]]this project is to use an LDR in place of a fixed value resistor which in turn generates a particular frequency. The generated frequency corresponds to the light conditions of the ambience.This concept finds popular application in motor speed control where the output is connected to motor driver circuit. Disco light is another interesting application of the idea where the lighting pattern keeps on changing. The circuit of this project uses NE555 to generate a continuous series of pulses in astable mode. The frequency of these pulses is obtained based on values of two resistors and a capacitor. Keep on reading to find out more information on the circuit and its working.
Negative supply using 555 IC
This circuit and project demonstrates the application of 555 to generate negative supply. The negative supply produced is about 3 volts lesser than the applied [[wysiwyg_imageupload::]]voltage due to various losses. At times the circuit requires both negative and positive supply, which is not available in the batteries. IC555 includes two comparators, one RS flip-flop and other few discrete components like transistors, resistors etc. The biasing voltage (Vcc) is divided in three parts through voltage divider using same value of resistors R. from these 1/3 Vcc is given to non inverting terminal of trigger comparator and 2/3 Vcc is given to inverting terminal of threshold comparator. The outputs of both comparators are given to R and S inputs of flip-flop. The Q’ output is actual output of IC and Q output drives. In this project, 555 work in astable mode and produces a frequency of about 663 hertz.
Seismic sensor using opam and piezo sensor
The project on Seismic sensor circuit described here senses pressure variation or mechanical strain and responds by sounding a speaker. It can be used at [[wysiwyg_imageupload::]]prohibited places to alert any unwanted entry. Such sensors can be placed on the floors of these places and whenever an intrusion would occur, the speaker would go off. The term “Seismic” is used majorly for all the operations and processes related to the earth, its crust and lower layers. The similar areas are there where this sensor finds its applications: 1. Decoding natural vibrations under the earth’s crust through seismograph 2. Aid in large industrial processes of oil extraction drilling process, mining, tunnel construction etc.
Light sensor using photodiode and opam
The project about light sensor circuit shows the application of photodiode to detect the presence of light. This light sensor can be used as an intermediate circuit [[wysiwyg_imageupload::]]in various applications to detect the presence or absence of light. The sensitivity of the sensor can be adjusted using the preset. This circuit is based around a LM339 comparator along with variable capacitors, photodiode, LED and a solo resistor. A photodiode, used as a photo detector, generates current in the circuit when light incidents on it. The circuit of this project uses the photodiode in reverse bias mode with resistor R1. The LED at the output will glow when light falls on the diode. In such a condition, the inverting input drops to a lower value than the reference set at the non-inverting input and so the output goes providing the necessary forwards bias to the LED.

The circuit is used for decoration purpose or as an indicator. Flashing or dancing speed of LED’s can be varied with the help of variable resistor and various dancing pattern of light can be formed by slight change in the circuit. In this circuit 6 LED’s moves in one direction then again flow the opposite direction than previous. The circuit is based on two IC’s namely NE555 and CD4017 with few more components. 555 timer IC wired as an astable oscillator. In this circuit NE555 astable generates a clock for the circuit which provide a oscillating wave to the output pin 3 of IC1. You can vary the speed of oscillation with the help of VR1. The frequency of oscillation of 555 timer can be calculated by f=1.44/(R1+2*(VR1)*C1) and CD4017 is a CMOS counter/ divider IC. It take clock signal from the clock input and turn on the 10 output in sequence, each time when it receives clock input pulses. It is the most popular IC and extremely useful in various project like Light Chaser, Matrix Die. In order to understand the working of IC one must know about its individual pin.
