In today’s post, we are going to explain how to handle Jason Strings in Python. There is JSON module in python which is used for JSON string handling. Jason is very common in RESTfull APIs. JSON is the abbreviation of JavaScript Object Notation. Here is Tutorial about Python Dictionaries. We use Dictionary data structure for handling

  Adafruit has a very good explanation about GPS interfacing. You may follow that tutorial or continue here.   To view, the available USB to TTL converter devices use the following command ls /dev/ttyUSB* If you had installed pyserial then you may list all your available COM ports using this command via python python -m serial.tools.list_ports

We had mentioned using Raspberry PI GPIO as output in our previous post. Today we will talk about using Raspberry PI GPIO as input. We will try to read input from pushbuttons. We had connected pushbuttons as the Active Low state. Mean the pushbutton will remain in the Active High state unless we press any

After successfully installing raspbian into Raspberry PI, the first thing which comes into the mind of the embedded developer is to play with Raspberry PI GPIO. Because the very best advantage of this cheap computer is to use with external hardware through its GPIO. We are going to explain how to play with Rasberry PI GPIO’s

Timer0 of pic16f is popular and very basic for creating short delays or… for creating small timing pulses. It is an 8bit timer with high priority interrupt. Which makes it perfect for creating time-critical applications like frequency counter, some industrial timing control system or any medical or industrial grade application.

Accuracy is very important in Real-time applications. Especially with time-critical applications. so whenever we need something time critical we always need accurate timings. In such cases, we cannot rely on nop instructions based delays. We need something more powerful and more accurate. To handle this kind of errors we always use hardware-based timers. luckily Microchip pic

Introduction: The “OOK modulation” or On Off Keying Modulation is very popular now days due to VLC or Visible Light Communication. OOK modulation is easy to use and easy to  implement. As we can even implement this modulation using simple 555 timer IC. In this post we are going to explain How to implement OOK

Introduction It is very common problem to detect when an analog signal changes its value from positive to negative or vice versa. Zero cross detector is used to solve this kind of problems. Zero cross detector is Kind of Voltage comparators used to detect the change in waveform. Zero crossing is the cross of the
