+## Aim 
+To make a seismograph that detects vibrations of ground and plots a graph accordingly.
+
+
+## Hardware used
+- Arduino Uno
+- Operational Amplifier
+- Magnet wire(copper)
+- Neodymium magnets
+- Springs and metal rods
+
+## Details
+The project is based upon a fundamental principle of physics: Faradays’s law of electromagnetic induction. The design consists of two metal bars with magnets attached at their ends and held stationary using springs. The bars are positioned such that the magnet hangs close to the coil. The mechanical design is such that when ground shakes, magnet moves with respect to coils, thereby inducing an alternating EMF. This EMF is then recorded and a time graph is plotted accordingly.

+## Aim
+To make a dustbin that will open when you hover your hand over it.
+
+
+## Requirements
+- Arduino Uno
+- HC-SR04 Ultrasound Sensor
+- Servo motor (operating voltage: 6V DC , torque: 3.5 Kg.cm)
+- Battery (12V 3AH)
+- Jumper Cables
+- A foot pedal Dustbin
+- Breadboard
+
+
+## Details
+The ultrasound sensor is connected to the front of the dustbin and the servo is attached to a lever in the back which is a part of the foot pedal mechanism. A code is uploaded into the arduino which is used to accept inputs from the ultrasound sensor and direct the movements of the servo. The arduino is powered by the battery.

+
+Hence the dustbin is opened using the servo when an object hovers over it and is similarly closed when the object is removed.

+## Details
+There were two Bots actually and were meant to play badminton’s doubles game. The highlight of this game were how the two robots hit and hit back shuttle by collaborating each other.The National ABU Robocon 2015 took place in the Badminton Hall of the Shree Shiv Chhatrapati Sports Complex, Balewadi, Pune on 7 March 2015.
+
+BITS Pilani, Hyderabad campus participated first time in the competition with team leader Jayanth Kankipati and the faculty advisor YVD Rao sir. The team was sponsored by India Bank.Overall it was a good and a new experience. Both of our bots were working good, but we couldn’t win it.
+
+## Technical details
+The bot used 85 watt motors with Mecanum wheels powered by Motors and 2 lead acid batteries. The motors were operated at 24 volt. Several Servo Motors were used for the arm Mechanism and for hitting Pneumatics were used at 6 bar pressure.The gas was packed in PET containers. The bot was controlled by dummy arm Mechanism.
+The other bot had everything same except the wheels it used Omni wheels.

+## Aim
+To balance the ball automatically at the center of plate using PID controller and Machine Learning(supervised learning).
+
+
+## Hardware used
+- Breadboards.
+- Ultrasonic sensors HC SR04.
+- 9v battery power supply.
+- Jumper wires.
+- 1-Servo motor.
+- wood-to make the frame,platform and support.
+
+## Details
+The main aim of this project was to apply machine learning(Supervised Learning: Learning with the help of the given examples), to let the bot learn to balance the ball in one dimension(further it will be extended to 2 dimension).
+
+First we measure the distance (position) of the ball using ultrasound sensor. We then calculate the deviation of the ball from its mean position (center). For training we use joystick to train the model how much it should move the servo (which is used to rotate the plate) which is proportional to angle of deviation from mean.
+

+
+### Distance Measurement:
+For measuring the distance  or position of the ball on the plate we have used Ultrasound Sensor to determine the deviation of ball from the mean position (center) of plate. We have used two ultrasound sensor (second one would have been redundant in ideal cases as length of plate is known),but due to noisy measurement we had use two.
+
+### Joystick:
+We have used joystick as an input to train the Machine learning model to predict the response. While training we displace the ball and give input to the computer as in the form rotating the joystick, which should be proportional to the displacement from deviation from the mean position. Its basically like playing ATARI games but in real. There our expert human response according to visual input is given to the computer and the target value for a particular deviation.
+
+After training phase the “learned” model with its parameter was given to the Arduino which then ran and tried to balance the ball automatically. The Arduino measured the distance(position of the ball) the calculated how much it should jerk, using Servo in the right direction to bring the ball to its correct position using the model learned from us.

+
+## Aim
+This is a basic project to control a bot or any other appliance wirelessly using RF Module. It provides 4 output channels which can be increased or decreased by minor changes in the code.
+
+
+## Hardware Used
+- Arduino Mega
+- Arduino Uno R3
+- RF transmitter & Receiver module 433MHz
+- Breadboard
+- DC motors
+- Some jumper wires
+- 12V adapter
+
+
+## Description
+The transmitter was connected with the Arduino Uno and some push buttons to take inputs as a remote control.
+
+The receiver was connected to mega and output pins were further extended to a relay board, which in this case was used as Dual H-Bridge to control motors. This relay board can be replaced with a common relay board to control electrical appliances for home automation using the same code. The relay board was powered with a 12V adapter.
+
+<Image

+  alt='1'
+  width='auto'
+  height='auto'
+/>
+## Code
+Whenever a push button is pressed the corresponding pin changes it states either HIGH or LOW.
+
+### Transmitter code
+Virtual Wire lib was used to use RF.
+
+Pin no 12 was used as data pin for Tx .Pin no 7,6,5,4 were used as input pins for remote.
+
+Code can be found [here](https://github.com/rajatbansal427/RF-bot-controll-Room-automation/blob/master/transmitter_ro_aut.ino) 
+
+### Receiver code
+The Rx receives an string of characters in a message which is stored as buf[] and buflen is the max no of characters in the string.
+
+The Boolean data type is used to toggle state.

+-   2-60 rpm geared motors.
+-   1-LM358 motor driver.
+-   1 – External 9v power supply.
+
+## Details
+The bot works on the fact that when sound is in a certain direction, the sensor closer to it measures a higher change in value than the sensor away from it due to sound attenuation.This bot uses three Analog sound sensors in front,right and left of the bot to record the clap sounds. Turns 90 degrees in the direction of the clap and 45 degrees if the claps come from a direction in between the cardinal directions.
