My name is Abdul Rehman and I love to do Reasearch in Embedded Systems, Artificial Intelligence, Computer Vision and Engineering related fields. With 10+ years of experience in Research and Development field in Embedded systems I touched lot of technologies including Web development, and Mobile Application development. Now with the help of Social Presence, I like to share my knowledge and to document everything I learned and still learning.
DS18b20 is a temperature Sensor module which works on single wire protocol. The reason to choose DS18b20 as a temperature sensor is because, we can interface many DS18b20 sensors on single wire. So we do not need extra pins for interfacing as well as we also do not need analog pins. Because ESP8266 Nodemcu module […]
Reading the environment temperature is one of the most important task for the majority of the applications. We are going to use LM35 Temperature sensor with Arduino in this example. Even in embedded systems, temperature sensors are one of the most basic and most important sensors used in wide variety of products. Some of the […]
React bootstrap is a very handy and popular framework for using the bootstrap in React.js applications. Today we are going to create a react-bootstrap navbar example. In this example I will show you from a simplest navbar to a little bit complex one. So grab your keyboards and let’s get started. Installing react-bootstrap First thing […]
Today we are going to read analog input in Arduino and send that read value to Serial port via serial.println() function. After that we are going to create C# based winform application and read data coming from Arduino and display into a Textbox using delegate methods in C#. SerialPort Object in C# will help us […]
Kotlin coroutines makes network calls much easier. Specially all the async await like programming. Basically the biggest candidate before the coroutines were the asyncTask in Android. But thanks to the Kotlin coroutines we can easily do that task in much simpler way. In this example we are going to fetch a simple URL feed with […]
Here is the code to multiplex 4 digit 7 segment on Atmega8 using Timer 2 Interrupt. This code witll display digits array on seven segments. In our case we used 3024 to display on 7 segments.
Led blinking example is considered a hello world program for any Hardware based softwares. So today we are going to blink the LED in my Nexys 3 Board. This example will serve the both examples, VHDL as well as Verilog. First of all we will look for the VHDL example. VHDL LED blinking Code Here […]
Using STM32 ADC with Timer Trigger option it helps us to control the sampling time of the ADC. It also becomes important when we need to sample Audio or while making some waveform analysis options. In this tutorial we are going to extend our previous STM32 ADC+USART example, where we implemented the ADC basic single […]
In this post we are going to read ADC1 channel 10 on GPIO PC0 on STM32F4 Discovery board. First of all we will set the Clock PLL to run the discovery board on full speed with 168Mhz frequency. Later we initialize the USART with the baudrate of 230400 Kbps and finally we initialize the ADC […]
If you had done Android development before, you may be very well aware of the concept of the Activities and switching between activitis. Or passing data using bundles between activities. But when it comes to the Flutter we don’t talk about the activities anymore. Because of the more web friendly development, Flutter also call its […]
