   StaticJsonBuffer ArduinoJson  uses preallocated memory to store the data and this is possible due to StaticJsonBuffer. If one has to use this library then firstly they should create t he StaticJsonBuffer just like: StaticJsonBuffer<200> jsonBuffer; then it creates an  memory of 200 byte size which creates allocated memory in the system for storing the data static as the name tells it has fixed in size type of memory.Also we cannot reuse the memory once it gets allocated.it has high speed performance. DynamicJsonBuffer This library supports DynamicJsonBuffer since it has parameters for dynamic memory allocation but it will be more useful if we use this buffer in the machine having memory more than 10KB of RAM. to use this syntax is just similar. DynamicJsonBuffer jsonBuffer; This will create one dynamic memory for the system so that it can allocate it more precisely.its size is variable it stores the data in heap.while storing it take time and its somehow pro...

Mini CNC(Computerized Numeric Controller) using an Arduino :- Step1 :-   Collecting all the necessary items from the market includes the following list:- Arduino UNO(R3) L298N Two old DVD drives Step2 :-   Creating the structure of the project.As i was using the old DVD drives here so i was used to design all the layout of my printer on the DVD drive also we have  used some type of 'jugaad' here to create the x axis of our CNC printer since i have less timings to complete our project and also to lower the cost of our project we use this wooden cardboards which i have cutted in a proper manner so that when we give the input it runs on x-y axis.               Basic structure of my project Components Used :-       HARWARE REQUIREMENTS :- Old DVD writers L298N Stepper Motor Drivers Connecting Wires Servo motors Arduino UNO         SOFTWAR...

How To Make Raspberry-pi ip-Address Static and show an virtual window of raspberry-pi on Windows desktop through VNC-Viewer STEP  1: Disconnect your Desktop from Windows operating system. STEP  2: Connect your Raspberry-pi to your pc install the Raspbian from the below link STEP  3: Download BalenaEtcher which is basically an image flasher which is going to flash the image of the OS that is Raspbian on the SD card on any USB  for further details go to the link below and download it. Also you can download Win32diskmanger to flash the OS STEP  4: Now as we download the Raspbian and also we flash it now Download the VNC viewer through the below link  STEP  5: Now open the Terminal on Rasberry-pi and write the following commands 1. ifconfig : Check out the  ip-address , sub-net mask 2. netstat -nr : This command will tell you about the  gateway address 3. sudo nano /etc/network/interfaces : This command will give the netwo...

Arduino UNO R3 Arduino Uno is a microcontroller board based on ATmega328P . It has 14 digital input/output pins 6 Analog pins a 16 MHz quartz crystal oscillator with USB connection ,a power jack , an ICSP(In-Circuit Serial programming) header and a reset button actually it has two reset buttons . Also Arduino uno has RX-0,TX-1 that is receiving and transmitting pins on board. Arduino uno contains  AREF pin which means Analogue-Reference IOREF pin this pin is provides a voltage  reference at which the microcontrller works 3-ground pins 3-Vcc pins Basically the purpose of creating an Arduino Uno is to Control the sensors and the actuators so that it can work accordingly the data which we provide with the help of software . Nowadays people using Arduino Uno in many fields it has very huge scope in  the field of  IOT(Internet Of Things). Also in my current project which is 2D-printer we have used Arduino Uno which sense the Data and according...
