T X, R X, D 2, D 3, D 4, D 5, V IN, GROUND 3.3 VOLT pin AND 5 VOLT pin. Where D3 and D5 are PWM pins. V in (input voltage) is used to supply voltage to Arduino broad (5-12 volt). The 3.3 volt pin is connected to a blue-tooth module HC-06. The 5 volt is connected to the two enable pins E1 and E2 and the Vin (input voltage) of the motor driver is L293D. D 2, D 3, D 4 and D 5 are connected to the four input pin of motor driver ( D 2 is connected to input 1 and D 3 is connected to input 2 which give the supply to one of the H- bridge of L293D in order to drive the right motor. D 4 and D 5 are connected to input 3 and input 4 which give the supply to second of the H-bridge of L293D in order to drive the left motor). The 3.3 volt pin is connected to the V in of bluetooth module HC-06. The T X pin of the blue-tooth module is connected to R X pin of the micro-controller broad and the R X pin of blue-tooth module is connected to the T X of microcontroller broad. The four output pin of L293D are connected to a DC gear motor. Output 1 and output 2 are connected to a right DC gear motor and output 3 and output 4 are connected to left DC gear motor and these motor take a supply voltage from pin 8 (v cc2 ) of L293D in order to give a supply to complete project we have used four mobile batteries of 3.7 volt and 900 ma each and all are connected in series with each other which gives a total supply of 15 volt but it is un bear able for Arduino broad so we have taking 7.5 volt from the second battery and we have giving to the Arduino broad as input. The total supply 15 volt is giving to the v cc2 (pin 8) of the motor driver for the supply of motor because the vcc2 pin (pin 8) of motor driver can bear up to 36 volt. The 900 ma batteries are used in order to provide a backup up to 5 hours to our project. We have use a charging pin [6] in order to charge our battery bank. The two terminals of charging are connected to positive terminal of the first battery and the negative terminal of last battery. We have used two sided connectivity switch. One side connectivity is used to give supply to v cc2 pin (pin 8) of L293D and the second connectivity side is connected to the charging pin in order to charge the battery. A push button is also used to provide 7.5 volt to the Arduino broad. A 2A and 16 volt charger is used to charge the batteries which take 1 and half hour to full charge. A small wireless camera is mounted on our project which takes a supply of 6-9 volt to operate so we have use 7.5 volt to turn on the camera. This wireless camera takes video and audio and transmits it to the user end. B. MIT App Inventor MIT app inverter is an open source [7] web application which is provided by Google.
