Hey folks,  In this tutorial we will learn how to interface Servo motor with NodeMcu(ESP8266)module and operate it with the Blynk app.  Servos  are controlled by sending an electrical pulse of variable width, or pulse width modulation (PWM), through the control wire. There is a minimum pulse, a maximum pulse, and a repetition rate. A  servo motor  can usually only turn 90° in either direction for a total of 180° movement. servo Motor (Back view)  Servo Motor (front view) Blynk  is a Platform with iOS and Android  apps  to control Arduino, Raspberry Pi and the likes over the Internet. It's a digital dashboard where you can build a graphic interface for your project by simply dragging and dropping widgets.

Hey Folks, In this tutorial, we will learn, how to change the colour of RGB LED using accelerometer of the ARM (FRDM-KL25Z). INTRODUCTION The FRDM-KL25Z is an ultra-low-cost development platform for Kinetis L Series KL1x (KL14/15) and KL2x (KL24/25) MCUs built on ARM® Cortex™-M0+ processor.  The FRDM-KL25Z has been designed by NXP in collaboration with mbed for prototyping all sorts of devices, especially those requiring the size and price point offered by Cortex-M0+ and the power of USB Host and Device. The FRDM-KL25Z is supported by a range of NXP and third-party development software. It is packaged as a development board with connectors to break out to stripboard and breadboard and includes a built-in USB FLASH programmer.               FEATURES NXP KL25Z Kinetis KL2x MCU (MKL25Z128VLK4) High-performance ARM® Cortex™-M0+ Core 48MHz, 16KB RAM, 128KB FLASH USB (Host/Device) SPI (2) I2C (2) UART (3) PWM (TPM) ADC (16 bit) DAC (1x 12bit) Touch Se

Hey Folks, In this tutorial, we will learn, how to interface DHT 11 with Node Mcu(ESP8266 ).   The  DHT11  is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed).

In this tutorial, we will learn how to interface a switch(push button) with ATMEGA16 using AVR studio. In the previous video, we learnt how to interface LEDs with ATMEGA16 using AVR studio. The push-button is a component that connects two points in a circuit when you press it. The example turns on an LED when you press the button. Here we have connected two push button to PORT C in  PC0 & PC1. And for LEDs connection please refer my previous blog. Components Required:- AVR Controller(Atmega16) LEDs Push Button Connecting Wires USBASP Programmer Dump the following code after connection  and select chip ATMEGA 16. #include<avr/io.h> #include<util/delay.h> void main()  {    DDRB=0b11111111;    int S1;    int S2;      while(1)    {     S1=PINC&0b00000001;     S2=PINC&0b00000010;     if(S1==0b00000001)     {      PORTB=0b00000001;      _delay_ms(100);      }      if(S2==0b00000010)     {      PORTB=0b00000010;      _delay_ms(100);  

In this tutorial, we will learn, how to interface an LCD (liquid crystal display) with ARDUINO.  An LCD screen is an electronic display module having a flat panel display or we can say it’s an electronically modulated optical device that uses the light modulating properties of liquid crystals. We will interface a 16x2(16 columns and 2 rows) LCD. Other variations are also available like 8x1,10x2 etc. It is having a wide range of applications; they are also preferred over the 7-segment display as they are cheap, easily programmable and also have the leverage to display special characters. Now let us interface Components Required 16x2 LCD                   1No. Resistor 560ohms        1No. Potentiometer 10k      1No. Arduino UNO               1No. Few connecting wires Breadboard Follow the image below for circuit connection reference. After making the circuit dump the code given below. #include<LiquidCrystal.h> LiquidCry

In this tutorial, we will learn how to interface LED with Atmega16 using AVR Studio . An embedded system is built around a processor. The design goals of an embedded system are to reduce size, cost and power consumption and to increase performance and reliability. The microprocessor we are using is ATMEGA16 . The processor has limited internal memory, and if this is not sufficient for a given application external memory devices are used. The hardware also includes any components that facilitate the user-application interaction such as display units, keypad. The light-emitting diodes are used for getting status information, such as power on, check output(high/low). You all must have observed led decoration lights, which can glow in different patterns. First, we will learn to interface a single Led and then 8 LEDs to learn a simple toggling technique. Components Required:- AVR controller(Atmega16) LEDs Connecting wires USBASP Programmer For

In this tutorial, we will learn how to interface a 7 SEGMENT DISPLAY with Arduino. A 7 SEGMENT DISPLAY consists of 8 LEDs and 10 pins,2 common pins are shorted and supplied with 5 volts from Arduino through a resistor and other 8 pins are connected to digital and analog pins. 7 Segment Display can act as a substitute for LCDs if we want to display numbers. Shown below is the internal architecture of a 7 segment display. Now let’s interface the 7 SEGMENT DISPLAY. Components required Arduino Uno                       1No. 7 Segment Display              1No. Resistors                             1No.            100 ohms             Connecting Wires Breadboard There are two types of LED 7-segment display The common cathode (CC)  Common anode (CA) In CC type the cathode of all the LEDs is connected together and similarly in CA type. In CC type we have to ground the common cathode pin and power up segments to illuminate it, the reverse happens
