Week 12 (FYP2): Test all function of trolley follower

Objective for this week: I test the function of the moving trolley, component, system coding and find little new form so that the trolley is always stable in the presentation later.

The above picture shows the entire project completed posted trolley follower including coding system that can control the movement of the trolley follower.

Here I will describe each function in the trolley follower:

1. Arduino Uno 

Arduino Uno function is to control the trolley follower, mean this Arduino is main function to control all component in trolley follower.

2. Ultrasonic sensor

Ultrasonic sensor is input device, ultrasonic sensor function here is to get the information or the movement of a human being and will send this information to process the system will be sent to the Arduino UNO.

3. Motor 

Motor function to movement the trolley follower.

4. Battery

for this trolley follower, i sue two battery, first for Arduino Uno and second for control the motor. 

for arduino i use 12V, 1.2Ah. for motor i use 12V, 7.2Ah because motor use 12v and 60rpm, so supply larger than arduino.

Week 11 (FYP2): Addition component and modified the coding

Objective for this week: go to JALAN PASAR buy new addition component and set new coding for addition component and test burn the coding to hardware.

1. first go to JALAN PASAR buy the component:

component have buy is:

• switch 
• cable jumper
• L298 motor drive module
• Donut board

2. second addition and edit the coding for motor controller, below picture show the coding:

by coding the above, I have made ​​some changes in the coding of the motor controller. Here I have added two motor coding, including one to move to the left, while the other one to move to the right.

On motor coding I have set the appropriate speed and distance is suitable for both motor.

this week, I've added coding hardware and repair coding motor controller.

Week 10 (FYP2): Modified harware and second briefing

 Objective for this week: This week I made ​​some adjustments and additions to the my project hardware with a new idea and it looks better. for this week have a second briefing.

1. below show my additions for my project trolley follower.

this i use for connection ultrasonic sensor and design for stability of my motor. i use pipe, iron and perspex.

This for all connection when addition new hardware part.

2. For this week have a second briefing :

• Explanation about poster
• Explanation about the Thesis for FYP

Week 9: Welding Motor and construct hardware

Objective for this week: for this week i go to welding shop to welding my motor and set all construct hardware of trolley follower.

1. first i go to welding to welding connection my motor drive to control the wheels for my trolley follower.
below show the welding motor:

This picture show i go to shop welding for welding my connection motor to control the trolley movement.

2. below show my construct my hardware for trolley follower:

first drill board and design connection drive motor to motor controller.

this design for connection ultrasonic sensor.

This all connection design.

For this week I did all the connection components to do experiments on every function, including board test, test and test ultrasonic sensor motor. for this week i go to welding my motor connection.

Week 8 (FYP2): Design connection motor driver to arduino and choose best wheels for trolley follower.

Objective for this week:  for this week design for motor drive, how many inputs and outputs needed to control the arduino and also controls motor movement system to run the trolley. This week also choose the right tires for use in the movement of the trolley.

1. The figure below shows the design for motor drive use PROTELL99SE.

In motor drive, use a 12 V or 9 V by the heavy load trolley, trolley follower but to use 12 V in order to move the trolley follower. By using two motor left and right and has been set to arduino distance and speed of the motor movement.

Motor drive will detect two signals from the arduino ultrasonic sensor signal of the left and right. based on the signal, the motor will move according to the distance and speed set assigned.

In arduino have code Writes an analog value (PWM wave) to a pin. Can be used to drive a motor at various speeds. After a call to analogWrite(), the pin will generate a steady square wave of the specified duty cycle until the next call to analogWrite() (or a call to digitalRead() or digitalWrite() on the same pin). The frequency of the PWM signal on most pins is approximately 490 Hz. On the Uno and similar boards, pins 5 and 6 have a frequency of approximately 980 Hz. Pins 3 and 11 on the Leonardo also run at 980 Hz
