Interfacing 7 Segment with ARM

Hey Folks, In this tutorial, we will learn how to interface a Seven Segment Display with ARM(FRDM-KL25Z).

Components Required
  • FRDM-KL25Z board
  • Seven Segment Display (Common Cathode)
  • Breadboard Mini
  • Jumper Wires (As Required)
  1. FRDM-KL25Z
      2. Seven Segment Display
 
     3.Breadboard Mini
 
 

    4. Jumper Wires (Male to Male)


 Follow the Image below for circuit connection reference:-


 (Interfacing all components)

After making the circuit dump the code given below:-

#include "mbed.h"
BusOut display(PTA1,PTA2,PTD4,PTA12,PTA4,PTA5,PTC8,PTC9);
int main() {
        while(1) {
       
        display=0xBF;
        wait(1);
        display=0x86;
        wait(1);
        display=0xDB;
        wait(1);
        display=0xCF;
        wait(1);
        display=0xE6;
        wait(1);
        display=0xED;
        wait(1);
        display=0xFD;
        wait(1);
        display=0x87;
        wait(1);
        display=0xFF;
        wait(1);
        display=0xEF;
        wait(1);
    }
}


After dumping the code the output is shown on the video below:-

IoT - LPG Gas Sensor Logging with NodeMCU and Thingspeak.

In this tutorial, will learn, how to interface MQ-5 Module with Node Mcu(ESP8266).

The Grove - Gas Sensor(MQ5) module is useful for gas leakage detection (in home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by using the potentiometer.

IoT - Humidity and Temperature Logging using NodeMCU and ThingSpeak

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).

Getting Started with Embedded System Design on AVR

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.
