Flow Chart Working of Touchscreen Pads

Every student uses Smartphones has a question - How touchscreen works?  It is simple to learn a Smartphone screen works. It is almost similar in all types of touchscreen phones.
Let's start with the Introduction:
Touchscreen- It is the 2-dimensional electronic sensing device that detects the presence as well as the location of the object eg. finger or stylus, touched on the display screen area.

When we touch eg. our finger on the display of a Smartphone, The uniform electrostatic field lying beneath the touchscreen of the phone, gets disturbed and sends a signal with the coordinates location to the processor. The processor analysis the point of location and presence and perform the function accordingly stored in it. The program of every function is defined in the processor by the developers so that it can perform and analyze accordingly.

See the Below picture to understand the better working of a touch screen..

Explained Processes:
1. Signals travel from the touch screen to the processor as electrical impulses.

2. The processor uses software to analyze the data and determine the features of each touch. This includes size, shape and location of the affected area on the screen. If necessary, the processor arranges touches with similar features into groups. If you move your finger, the processor calculates the difference between the starting point and ending point of your touch.

3. The processor uses its gesture-interpretation software to determine which gesture you made. It combines your physical movement with information about which application you were using and what the application was doing when you touched the screen.

4. The processor relays your instructions to the program in use. If necessary, it also sends commands to the Smartphone's screen and other hardware. If the raw data doesn't match any applicable gestures or commands, the Smartphone disregards it as an extraneous touch.

Notice that all these steps happen in a nanosecond. It takes Smartphones to process your touch as fast as possible and generally the fast processing depends on the Processor's processing speed and built up of a Phone.

    Great article on touchscreen technology! The flow chart made the concepts easy to understand. I've been using the ELO 1717L from Esaitech, and it's been a fantastic addition to my setup. Highly recommend it!

Buzzer interface with 8051 microcontroller

Buzzer  is a electronic device that converts the electronic signal into buzzing noise, that is applied to it. It can be used as electronic bell or as quiz buzzer in many applications around us. Here, i world like to discuss the interfacing of a small buzzer with 8051 microcontroller and how different projects can be constructed. Buzzer Interfacing: This project shows the interface with AT89S52 microcontroller to a buzzer. When a push button is pressed, the buzzer will get ON and OFF ( number of times set in the code ) and then stops. Circuit Diagram: - The port P1 of the microcontroller is connected to buzzer. This type of connection is possible, if the current requirements of the buzzer is not more than 20mA. The output is in current source mode so that buzzer will turn ON when the output of the port is logic LOW. Switch is connected to port P3 which remains at logic HIGH by pull up resistor.  Code: #include "REG52.h" #define buz P1 sbit SW=P3^0; long int i; voi

Different ways to generate delays in 8051

The delay length in 8051 microcontroller depends on three factors: The crystal frequency the number of clock per machine the C compiler. The original 8051 used 1/12 of the crystal oscillator frequency as one machine cycle. In other words, each machine cycle is equal to 12 clocks period of the crystal frequency connected to X1-X2 pins of 8051. To speed up the 8051, many recent versions of the 8051 have reduced the number of clocks per machine cycle from 12 to four, or even one. The frequency for the timer is always 1/12th the frequency of the crystal attached to the 8051, regardless of the 8051 version. In other words, AT89C51, DS5000, and DS89C4x0 the duration of the time to execute an instruction varies, but they all use 1/12th of the crystal's oscillator frequency for the clock source. 8051 has two different ways to generate time delay using C programming, regardless of 8051 version. The first method is simply using Loop   program function in which Delay() function i

How to Switch OFF Citizen Calculator

You might be confused on seeing no OFF button on your calculator. Actually, these are general calculator available at low cost in the market. They process simple calculations like division, subtraction, Addition, Multiplication. But, how will you OFF that calculator having no option on them. There is always a trick which OFF them. It depends on the company calculator and their series to which they belong. I can tell you about Citizen Calculator CT-500 (as you can see in the image), how can you switch OFF it and can save battery too. If you leave calculator idle for 6-7 minutes, it will goes OFF automatically. My calculator goes OFF in 6.50 minutes from the point of leaving it idle. But, this is not the power saving trick for these types of calculator having not much backup battery. To save the power of your normal calculator, here is the trick to switch OFF it. Press ' /(divide sign)', 'x(multiply sign)', '%(percentage sign)', 'autoreplay option(
