Measuring Distance using Ultrasonic sensor and Arduino: Ultrasonic sensor:          Ultrasonic sensors emit short, high-frequency sound pulses at regular intervals. These propagate in the air at the velocity of sound. If they strike an object, then they are reflected back as echo signals to the sensor, which itself computes the distance to the target based on the time-span between emitting the signal and receiving the echo.                As the distance to an object is determined by measuring the time of flight and not by the intensity of the sound, ultrasonic sensors are excellent at suppressing background interference.      Virtually all materials which reflect sound can be detected, regardless of their colour. Even transparent materials or thin foils represent no problem for an ultrasonic sensor.       Microsonic ultrasonic sensors are suitable for target distances from 20 mm to 10 m and as they measure the time of flight they can ascertain a measurement with pinp

9V battery Break down and Analysis: Battery: An electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, and electric cars. When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode.   Cell: An electrochemical cell   is a device capable of either generating electrical energy from  chemical reactions  or using electrical energy to cause chemical reactions.           Coming to the 9v battery The  nine-volt battery , or  9-volt battery , is a common size of battery that was introduced for the early transistor radios. It has a rectangular prism shape with rounded edges and a polarized snap connector at the top. This type is commonly used in walkie-talkie, clocks and smoke detectors. The nine-volt battery format is commonly available in primary carbon-zinc and alkaline chemistry, in primary lithiu

LCD DISPLAY INTERFACING WITH ARDUINO         Ardunio playing a vital role in present electronics fields and technical market. We can build different projects simply by using Ardunio due to its compatibility with various sensors.                   Ardunio can be easily connect With wide of sensors, offcourse programme dumping and It's operating procedures is also very simple with less complexity. Ardunio Uno is the highly prefered board due it's low and better features than Mega and Nano.           Coming to the 16x2 LCD display interfacing with Arduino         16x2 LCD display is a 16 pins Liquid Cristal Display. It looks as follows                          Vcc or Vss - supply pin              Vdd or GND- ground               E - enable              D0 - D7 - Data pins              A and K - Anode and cathode The interfacing circuit of 16x2 LCD display and Arduino Uno is as follows Process of Dumping program code :                 we can dump the cod

water level indicator       water level indicator is a simple electronic circuit which can be made with transistor ,LED and buzzer for indicating the levels of water in tank .          It gives an alart whenever  the tank is full and indicates different levels of water with various color LEDS.       This circuit mainly works on the transistor switch configuration i.e., whenever the base voltage of a transistor is at certain level it acts as switch and automatically connects emitter and collector and provides a path for current flow between them        Lets see the required components:         1. Transistor -BC547         2. Resistor -220 ohms         3. LED's - Different colors         4. Buzzer         5. connecting wires         6. Zero PCB       The whole process of process of making a water level indicator is in the below YouTube video  Acts of facts YouTube video on Water level indicator If you guys want the water level indicator in real time use
