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);
    }
}

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).

Servo Motor Control using ESP8266 and Blynk App

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.
   Follow the image below for circuit connection reference. In this circuit, we have connected the output pin to the D0 pin of the NodeMcu module. If want to control the servo motor manually then connect a 10K potetiometer . The 10K potentiometer will work as a voltage divisor, changing the analog input level on  NodeMCU (A0) from 0 to 3.3V. Internally, the 10 bits ADC (Analog-Digital converter) will generate a digital value (from 0 to 1023), the PotReading, equivalent to the analog voltage input.
After making the circuit dump the code given below.
