Introduction

This is my first blog but does not matters because a milliner starts with a penny only.
             
So this blog is all about the posting blogs so that readers can come to know about the on going or upcoming tech fests or the technical events in the Pune or outside Pune.


so show the sprit and be active

QUADRATURE ENCODER

Rotary encoder is a sensor attached to a rotating object (such as a shaft or motor) to measure rotation. By measuring rotation your robot can do things such as determine any displacement, velocity, acceleration, or the angle of a rotating sensor. 1.0 Introduction A typical rotary incremental encoder consists of a light-emitting diode (LED), a disk, and a light detector on the opposite side of the disk (see next figure). The disk, which is mounted on the rotating shaft, has patterns of opaque and transparent sectors coded into the disk. As the disk rotates, the opaque segments block the light and, where the glass is clear, light is allowed to pass. This generates square-wave pulses, which can then be interpreted into position or motion. These pulses can be read by microcontroller as part of a PID feedback cont System to determine translation to distance, rotational velocity, and/or angle of a moving robot or robot part. For instance, if you have a wheel rotatin

Distance On LCD   In this blog the distance measured by the Ultrasonic Sensor is Displayed on the LCD display using Arduino. Ultrasonic Sensor (HC-SR04) Ultrasonic ranging module HC - SR04 provides 2cm - 400cm non- contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitter, receiver and control circuit.  The basic Principle of work: Using IO trigger for at least 10us high level signal. The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back. IF the signal back, through high level, time of high output IO duration is the time from sending ultrasonic to returning. The total distance = (high level time x velocity of sound)/2 velocity of sound = 340 m/s Wire connections for the Module Complete circuit The module have 4 pins : VCC power supply Trigger Pulse Input Echo Pulse Output Ground 0V Connection with Arduino Connect Vcc to 5 V power supply from

Arduino with Speakers Project #01 a Introduction In this project the speaker will make sound whenever the infra red (IR) sensor connected to the Arduino detects any obstacle. Elements Required  Arduino Speakers Infra Red (IR) Sensors Breadboard Connecting Wires Infra Red (IR) Sensors  IR Sensors work by using a specific light sensor to detect a select light wavelength in the Infra-Red (IR) spectrum. By using an LED which produces light at the same wavelength as what the sensor is looking for, you can look at the intensity of the received light. When an object is close to the sensor, the light from the LED bounces off the object and into the light sensor. This results in a large jump in the intensity, which we already know can be detected using a threshold. IR Sensor Connection With Arduino Connections of IR Sensor The IR Sensor have three pins: Vcc : connect to 5V of Arduino GND: connect to Ground of Arduino O/P : Output connect to I/O pin of Ard
