BLINKING LED USING 555 IC

            BLINKING LED USING 555 IC


Components required:

                                          1)555 IC
                                          2)10k RESISTOR
                                          3)10uf CAPACITOR
                                          4)DC SUPPLY
                                          5)CONNECTING WIRES

Circuit Diagram:


Procedure:


          The 555 ic is the basic ic which helps in generation of square pulse where it can be adjusted by the resistor and thr capacitor used in it.The frequency can be calculated by formula 1.44/(R1+R2+R2)*C1 where the with of the wave can be controlled.
         The Pin 1 is ground and the pin 2 and pin 6 connected using wire and pin 3 is the output pin where pin 4 and pin 8 is connected using wire and pin 5 is constant and pin 6 and pin 7 joint using 10K resistor and pin 7 and pin 8 is connected using 10K resistor where 10uf capacitor small terminal is connected 2 pin of 555.
         The capacitor +ve pin connected to gnd pin and give the supply to 8 pin where 4 and 8 pin are positive it is connected using wires and -ve supply yo gnd Now the led glows as blinking


LETS CHECK HOW IS IT WORK:






                                                         POWERED BY
                                                                NBSL

SOIL MOISTURE SENSOR USING ARDUINO WITH CONNECTION AND CODE

SOIL MOISTURE SENSOR USING ARDUINO WITH CONNECTION AND CODE Soil moisture sensor is the sensing element which determine the volumetric amount of water in the soil .The sensor sense the amount of water by passing an minute voltage at its terminal .Then when the water presence is detected it send an minute voltage to the amplifying circuit and it is further amplified and send to the Arduino. Components Required:                       1) Arduino                       2) Soil Moisture sensor                       3) Led                       4) Connecting wires...

India Space Research

INDIAN SPACE RESEARCH                                      The Technology is developing day by day and new innovations are coming out day by day. Many things are runs with help of satellites for example TV receiver, Weather Forecasting, Global positioning systems(GPS), Defense purposes. Thus Aerospace development is very important for an country. INDIA , places 5 th place in space developments. The ISRO is the Indian organization of space research Developments. What is ISRO? ISRO expands as Indian Space Research Organization, which is the Indian space Development organization. ISRO Ranks 5 th place in space research. Who founded ISRO?  Indian Space Research Organization (ISRO) was founded by Jawaharlal Nehru, who is the First Prime Minister of INDIA and Scientist Vikram Sarabhai, who is known as the father of space programs in the year 1962 as Indian National Com...

How does ant walk in straight line

How does ant walk in straight line? Normally, Ants live as big colony and it is organized. When the ant found food it takes a small piece of food and returns to its colony, while returning from the food area to its colony ant releases chemical called pheromones with the help of pheromones  other ants in their colony goes to the food area and brings the food to their colony. The pheromones evaporates at certain time of interval so other ants which carry food also releases pheromones it helps in reaching of other ants from colony to reach food. Every each set of ant consists of unique set of pheromones so it helps to find other colony and its does not allow other colony ant to enter in their colony and even it attacks them. How does old book smell good? Smell of book is basically by the paper and ink and the paper is primarily made up of wood and the wood is made up of cellulose and lignin . Over years, the book is exposed to heat, light, moisture and it bega...
