Welcome to laros-education
Welcome to LarOs - eDucation
This web site is dedicated for all visitors and we'll give free tutorials about electronics and computer enginering.
The tutorials is exclusively to the Electronic projects such as MCS51 and AVR mirocontroller and related products (both hardware and software). This includes the traditional 8052, 8051, 8032, and 8031 along with more modern derivatives such as the Atmel AT89S51,AT89S52,AT89S53,AT89S8252, AVR ( AT90S series ) and many derivatives by Silicon Laboratories, Philips, and many others.
We have a tutorial section for the programmer or student that is just learning about the MCS-51 and AVR microcontroller. We have a reference section for the proficient developer who just needs to access some quick reference information.
Please spread the word about this site to friends and coworkers. Feel free to link to it on your web pages. If you have code or literature that you'd like to contribute to the site please contact us--we're interested in any and all material that we can get our hands on to pass on to other users of this site.

Display Keypad 4 x 4 with LCD Character 2 x16
After doing lesson 2.8.1. you can see that how easy to scan keypad
and read data out to LED. In this lesson it's look like lesson 2.8.2.
but the data will read out with LCD Character 2 x16.Figure 2.8.3.Keypad Connection to Microcont...
Display Keypad Data to LED
In this lesson we are like to design, how to scan keypad
4 x 4, and then display it to LED.Figure 2.8.2. Keypad connection and display to LED Step 1st
Build the circuit as shown in figure 2.8.2. As you seen on figure 2.2.8.

K E Y P A D 4 x 4 (2)
Keypads are often used as a primary input device for
embedded microcontrollers. The keypads actually consist of a number
of switches, connected in a row/column arrangement as shown in Fig 2.8.1.
In order for the ...
Generating a Stair Step Voltage from DAC
In this lesson we are like to design, how to generate
stair step voltage from 0volt trough 5 volt, with resolution 1 volt
each step. There is something you must to do is to calculate the konstanta
K, as you have learn...
Simple Experiment to Generate a Voltage from DAC
In this lesson we are like to design, how to generate
a voltage 2 volt from DAC0808. There is something you must to do is
to calculate the konstanta K, as you have learned in previous lesson.Step 1st
Build the circuit ...
Build Digital to Analog Converter Using 0808
The first task this week is to build a simple D/A convertor
and evaluate its performance. You will be using a DAC0808 (DAC0808 datasheet).Your
design should take 8 bits from the microcontroller (use the 8 8bits
on Por...
Displaying data ADC 0804 in 8x7 Segmen as a Decimal(2)
Step 1st
Build the circuit as shown in figure 2.5.2. As you seen on figure 2.5.2.
P3.0 trough P3.7 is connected to DB0 - DB7 ADC0804, and P2.0- P2.7.
is connected to transistor driver, and P3.0 trough P3.7. is connecte...
Simulating to Display Temperature by Using Look Up Table
WHAT IS THE LOOK UP TABLE ?
Why do we need a look up tabel ? Look up tabel is just
couple data that safe in ROM and it's used to manipulate data. So we
can avoid a very confusing prosess of math. In this case we are goi...
Displaying data ADC 0804 in 8x7 Segmen as a Decimal
In this lesson will be learn how to display data ADC on 8 x
7 segmen, for a simple task, we assume ADC have input ranges 0 - 5 volt,
and then will display data as desimal that must be 3 digit 0 - 255,
and each digit w...
