A microprocessor controlled toy car

In this week, our group had a bottleneck on the code of motors. Due to the lack of experience in Arduino programming, we spent a whole day but there were few results. However, the process of constructing the main body of car was prosperous extremely.  Summary of week's activities : 1. Work on the code of motors. 2. The main body of the car. Working on the chassis of the car and adding the wheel with the motors. Hand drill the board for the motor to finish the chassis.  Working on the code for the arduino and the Bluetooth module and Try to finish the code and make it work.  Problem, issues and concerns : W e did not familiar with the principle of the board and the logic of code, so the works were inefficient. If we just entered the code of Bluetooth, we could observe the correct data in the serial monitor. When we added the code, which could control the motor into original one there was a infinite loop where t...

In this week, our group  finish the work on the chassis of the car and finish the coding of the Bluetooth and the code of the motor and test them. soldering wires for the batteries. Hand drill some slots for the Arduino board and DC Motor shield.Adding photo to the blog. Summary of week's activities : 1. Finish the code of motors. 2. Finish the code of the Bluetooth. 3. Finish the chassis of the car. finish the work on the chassis of the car and test all the motor together and fix the wheels and make sure that all of them working before week 5. Finish all the coding of the Bluetooth and the motor fix the problem that we had in week 3 in the coding for both the motor and the Bluetooth. Test the code with the app and they are work successfully. Problem, issues and concerns : Finish 90% of the project and all the thing work successfully and only connect the motor with the other components. Plan for next week : Connect the arduino with the DC shield with the B...

In this week, the group worked on the Bluetooth function. The objects of that were setting the Bluetooth into AT mode and connected it to a Android phone and the Bluetooth can receive the instructions, which were transmitted by controlling on the APP called .  Summary of week's activities : 1. The HC-05 Bluetooth entered into the AT mode. Firstly, connecting Rx pin of the Bluetooth module to pin 11 of Arduino Uno, and Tx pin of Bluetooth to pin 10 of Arduino. Also connect  ground to ground, but don't connect the Vcc yet.  Figure 1: Bluetooth connected with board Secondly, we input the code into the Arduino IDE. After we compiled and uploaded the code, opened the serial monitor and changed the  "no line ending " to "both NL & CR". Due to the default baud rate of this Bluetooth was 9600baud, we set the baud rate to 9600baud.  The circuit and the code had gotten ready, we found the light on the Bluetooth kept flashed for 2 seconds and kept dar...

The aim of this project is that constructing a car with microprocessor controlled by the Bluetooth.   Group member :  Hamad Almansour   Stephen Swinney  Jianqiao Du Supervisor :  Dr . Mark Bowden  Summary of week's activities : 1. Check the components 2. Connect the microprocessor board to the motor shield  3. Write the preliminary code 4. Connect the batteries to test the circuit Problem, issues and concerns : 1. We did not have a stuff, which could play the role as a car body. So we considered that perhaps a piece of  thick box or a plastic board will be suitable.  2. After entering the code to the microprocess, we were not sure whether the motor shield could make the motors operate or not. When we connected the motor to the circuit and turned on the power supply, it could not operate. However, it operated when we connected to the power supply directly. In this case, we considered that th...
