In this week, there been held the FYP briefing to guide student about how to write the report properly and gain maximum marks and knowledge to implemented to the work environment.For the report writing updating process, the focus is more to the chapter 1, 2 and 3 but yet not finishing the chapter 3 (methodology) because the process of this project still ongoing and it will be updating from time to time.
2. Project In this week I start to buy a component.
Search and construct ultrasonic sensor max sonar-EZ1 circuit.
Objective :
Use suitable sensor that can relate or function with PIC16F877A
Content/procedure : Component needed
LCD
Maxsonar EZ1
NPN transistor 2N2222
Breadboard
Jumper Wire
Resistor (1k & 4.7k)
Circuit Connection
Simulation Connection
Result and analysis :
Maxsonar-EZ1
The Maxsonar-EZ1 sensor offer a very short to long range detection which is from 0-inches to 254-inches plus with a very low power consumption. It has provided sonar range information from 6-inches out to 254-inches with 1-inches resolution. Object from 0-inches to 6-inches are range as 6-inches. It has 3 modes selection for the output range which is:
The Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) module is a serial I/O communication peripheral. It is also known as Serial Communications Interface (SCI). It contains all clock generators, shift registers and data buffers necessary to perform an input or output serial data transfer independently of the device program execution. As its name states, apart from the usage of clock for synchronization, this module can also establish asynchronous connection, which makes it irreplaceable in some applications.
Conclusion :
Maxsonar-EZ1 will send the output if in ASCII format. For maxsonar-EZ1 sensor, the output are in RS232 format which mean that the HIGH(1) bit are at 0V while the LOW(0) bit are 5V, so need to connect the TX of sensor connect to NPN while RX of sensor to TX of microcontroller as shown in figure above.
I'm attending the briefing about FYP at Gemilang Hall, UniKL BMI by FYP Committee about the what to do and not to do. Just like the ordinary briefing like last semester that tell the basic thing and just adding the info about Engineering Day's shirt and the new features like this blog so on.
In this week also I got to meet my project supervisor to discussing about the progress of my project. Basically my project had undergo the simulation development but I just complete half of it. The sensor and camera part still in research in order to combine it with the main micro controller. Futhermore, I had bought some of the components to be used in this project.
