All these process is shown step by step in the below video on youtube.Comment if you have any queries.:
VSPE (Virtual Serial Port Emulator) is a software which provides us the utility to access multiple com ports on the same PC. We can create new serial ports virtually and can connect them as we want. For example I can create 2 serial COM ports and if I pair them then they will be connected with each other. So that I can run two applications
All of the electronics engineering students mostly want to create something which has a nice GUI control for their device. But they see softwares like VB6, VB.NET as pure software language. On the other side, Computer engineering students see also these software as pure GUI. Electronics geeks know the hardware and computer geeks know software. But Actually these languages such as VB6, VB.NET, Java can provide us very useful features to control our hardware connected to PCs. Here i am presenting a very basic tutorial to access serial port of PC in the VB6 software.
We will create the GUI (Graphical User Interface) which contains some buttons. Pressing them we can send some data to our PC’s serial port. Though it is a very basic tutorial but this is a must learn step. Further you can receive, send, monitor data, take some Continue reading
This system can provide all data like temperature, gas , door status of your home on PC screen. All data of parameters like temperature etc are stored in database and can generate Excel file so that you can view data of any day in history you want. This system is very useful in modern houses. Here for demo i am taking 2 sensors: Gas Sensor and a Temperature sensor LM35. The heart of the system is PIC16F887 microcontroller. It monitors both our digital Continue reading
This system is ideal for companies which have many manufacturing units.. The system mainly works to help the manufacturing unit to get data of current product quantity and to process this data. In this whole article I am taking example of a company which manufactures pipes. So here product1, product2, product3 … in this article can be circular pipe, triangular pipes, square pipes etc… Many types of pipes.
Conventionally, the company’s manufacturing plants use the product counters to count their product quantity manufactured. Normally these types of systems are equipped with 7-segment displays. Hence whenever Continue reading
Generally we set log in screens in our applications through which we can enter the details and get access. But some times we fear that if the password and id are lost or stolen then unauthorized user will access the system. Hence here i am suggesting a new idea to improve security. I am adding the hardware level security. I am using Continue reading
I recently posted an idea to control your home appliances using 8051 microcntroller here. For simulation of this post see the links below. The same can be implemented. But the respective changes will take place as follows:
The IDE used is now MPLAB X IDE.
Compiler is XC8.
Microcontroller is PIC16F887 Continue reading
