Lora Module Sx1278 (Ra-02) Interfacing With ESP8266 (NodeMCU)

Ankit jat

Interfacing Lora With NodeMCU




Ra-02 Work With ESP8266 Board

Lora Ra-02


In this article, I will teach you how to use the LoRa Module with a Nodemcu board. In this project, we will send a two-way message between two LoRa.

First of all, Collect the following devices -
  • 2 Lora Ra-02 (Sx1278) Module 
  • 2 MT7681 Antenna
  • 2 NodeMCU (ESP8266)
  • Some Jumper Wires
  • 2 Dc 5 Volt Supply For NodeMCU Either USB Or Input Pin

Now make Connections According to the table given below -
Lora Ra-02 NodeMCU
3.3V3.3V
GND (All Pins Compulsory)GND
NSSD8
MOSID7
MISOD6
SCKD5
RSTD0
DIOD2
Keep In Mind - 
    That you have to connect all GND pins of LoRa to GND of NodeMCU. If you leave even one of the pins open, your device will not work properly.

If you have looked at the datasheet of the Ra-02 model, you will find that the Ra-02 model only works between 410 - 525 MHz frequencies.
You will need to choose a frequency between these for this project. I am choosing 433 Mhz.

You have to install the LoRa library, you can download it from here and then add it to the Arduino software.

Now you have to upload the code given below in both the NodeMCU

Code -



Or

You can Download Code Here


Note - 
The same code is to be uploaded on both devices.

If there is an error uploading the code, you remove nodemcu from LoRa and then upload the code and re-add LoRa after uploading.
You have selected 115200 baud rate for both serial monitors

Finally, after everything is successful, you need to open the serial monitor, if it says "Device Activated" it means all your system is working properly, now you can send and receive messages. If you see a "LoRa error" written on the serial monitor, you should thoroughly check your connections as well as the frequency recorded.

To send a message you have to go to any serial monitor, type the message in its input box, and press enter, your message will be sent to another LoRa module. and it will appear on the second serial monitor

Ultrasonic Distance Measurement using Arduino uno

Ankit jat

Ultrasonic Sensor Interface With Arduino Uno

Ultrasonic Sensor Distance Measurement Code 

In this post, I will tell you how we can make a distance measuring device with the help of ultrasonic sensors and Arduino Uno.


Ultrasonic Sensor -
 

Collect The Following Components -
  • Arduino Uno                                 Buy on Amazon
  • Ultrasonic Sensor                          Buy on Amazon
  • 16x2 LCD Display                          Buy on Amazon
  • Jumper Wires
  • Bread Board
Follow This Steps - 

1) Make the electric circuit according to the picture given below.
PDF Download - HC-SR04
2) Copy the code given below.



 Or
Download Ultrasonic.ino file
 
3) Now open the Arduino software and create a new file in it. Paste the code you copied it or open the Arduino software by double-tapping on the downloaded file.
 
4) Compile And upload this code in Arduino UNO. 
 
5) Now you test your project. You can see the distance on the LCD screen as well as on the Serial monitor of Arduino Software. For this, you have to set the baud rate at 9600 of the serial monitor.

Note -

  • You can use this device only to measure the distance from 2 centimeters to 400 centimeters.
  • Low accuracy
Result -

Look Ahead Carry adder 

Fast Carry Adder 

In This Post, I will tell you about a fast carry adder or look ahead carry adder. 

Fast Carry Adder 
Fast carry adder is a modulated form of n bit parallel adder. This type of adder consumes low summation time as compared to normal n bit parallel adder. 

Why n bit Parallel adder consume more time?
