  INFRARED SENSOR WORKING TUTORIAl WITH ARDUINO INFRARED SENSOR:                                       The infrared sensor are the obstacle detection sensor with detects the object in front of it and it consists of the ir transmitter and the ir receiver in it.The infrared sensor consists of the trimmed capacitor in it so the detection of object can be controlled with it.It has the 5v input and Gnd in it and has the output pin it when obstacle detected the votage comes through it.Let's see the working tutorial of it with aurdino. COMPONENTS REQUIRED:                                    1)INFRARED SENSOR  ...

                         ARDUINO SENSORS 1) INFRARED SENSOR IR (infrared) sensors detect infrared light. The IR light is transformed into an electric current, and this is detected by a voltage or amperage detector.A property of light-emitting diodes (LEDs) is that they produce a certain wavelength of light when an electric current is applied--but they also produce a current when they are subjected to the same wavelength light. A pair of IR LEDs can be used as motion detectors. The first IR LED is wired to emit LED and the second LED is wired to transmit a signal when it receives an IR input. When an object comes within range of the emitted IR, it reflects the IR back to the receiving LED and produces a signal. This signal can be used to open sliding doors, turn on a light or set off an alarm    2)ULTRASONIC SENSOR The energ...

5) Ferrari 488 GTB With a twin-turbo 3.9-liter V-8 located just behind the driver’s seat, the 488GTB generates a sonorous wail and ferocious acceleration all the way to 8000 rpm, where it makes 661 hp. A seven-speed dual-clutch automatic is the sole transmission; we estimate a zero to 60 time of 3.0 seconds. Ferrari’s adaptive suspension is relatively compliant without sacrificing handling. For those who want more V-8 music, the Spider offers a retractable hardtop that raises or lowers at speeds up to 25 mph.                 4) Porsche Carrera Engine The Max. torque 331 lb-ft and the Displacement 3.0 l  the Max. engine speed 7,500 rpm at rpm 6,500 rpm and Max. power per liter 123.3  and the Bore of 91.0 mm and the Exhaust emission treatment 2 catalytic converters 2 the cylinders Twin-turbocharged boxer 6  the Max. power 370 hp at rpm 1,700 - 5,000 rpm  at Stroke 76.0 mm and Power-to-weight ratio 9.3...
