Apr 24, 2017 A quick video looking at how to transfer sensor data captured in Arduino and sending it into your processing sketches. Simple and Easy Way to Read Strings Floats and Ints over Arduino Serial. Feb 27, 2012 Hi I would like to know how I can send the data to arduino using serial monitor. Can someone give me a code to do that. I want to enter ' to arduino which in turn should send it to the Tx pin a transceiver to put it to configuration mode. Apr 05, 2018 Build desktop applications to monitor & receive serial data from Arduino using Visual Basic.NET (VB.NET).
One Arduino records data and sends it over serial to a NodeMcu that sends it to data.sparkfun.com.
The 'record' sketch is for a uController that collects accelerometer data and sends it to the esp8266 uController.The 'esp8266' sketch receives the data over serial and sends it over wifi to data.Sparkfun.com

I used a teensy 3.2 uController teensy 3.2 to read a 200G accelerometer, Adafruit ADXL377.I used a NodeMcu for my esp8266.
Aug 15, 2019 Digital Radionics or Radionics Machine. What do you get first??? In an ideal world we would all have digital radionics software like Radionics Manifestor Pro and a traditional radionics machine to work with, but as we all know this is a far from an ideal world, the main factor in not having both for many is cost. Digital radionics free download.
The 'record' sketch reads a 200G accerlometer with any 3.3V arduino and sends the total accerlation (hit) to an ESP8266 over Serial. In this case I used a second serial hardware Serial1 as available in a Mega, teensy, leonardo uControllers. Could also use TX, pin 1 in an UNO with an appropriate level shifter.
ESP8266 sketch runs on an nodeMcu or any ESP8266 uController. The ESP8266 receives a serial value from an Arduino and sends data via HTTP GET requests to data.sparkfun.com service.
Connect your arduino TX pin the the ESP8266 RX pin as well as connect the ground pin. Both uController's need to be 3.3volt or a level shifter is required.
The first character received is a ~ (ASCII 126) and then the data (inputString) followed by an Arduino pirnt return (println) sends the final character (ASCII 13)
You need to get streamId and privateKey at data.sparkfun.com and paste them below. Or just customize this script to talk to other HTTP servers.

I tried to allow sending and receiving data using 2 Arduino Unos, 2 LORA chips (SX1278 433MHz), 2 antennas and 2 Arduino IDE.
Problem is with the receiving data command.
This is the code for SENDING command:
On serial monitor, I succeed in sending packages, but not receiving. This is the RECEIVING code:
I used instructions about connections from this git page:https://github.com/sandeepmistry/arduino-LoRa

To make this board work, I had to explicitly initialize SPI
It may be the same for yours. Also, you should properly initialize Lora:
With the code you posted, you don't really know if it initialized correcly or if it's actually sending any data.

First I haven't worked with Lora library. I worked with SX1278 libaray. So I can help you with that.At first here is the link to the libaray - Lora SX1278.h library
Now you might ask why I'm not using the library from the original GitHub repo. Well I faced issue with that library and the issue is this:
The sx1278::getPacket() library function is modified to stabilize the Lora receive functionality. There was a bug which led the esp to panic. The payloadlength read from the REG_FIFO register was not checked for valid value which led to reading the REG_FIFO register read for over 65000 times. Moreover yield() is added in time consuming parts of this function.

That is why I'm using this custom library. Anyway, for you:You can use this function to send packet:
Also to receive data use this function:

And at the beginning of the code just define this few things:
