Reading and sending data from serial port (USB) with arduino is 'a piece of cake' compared with the same task using PIC 18F2550, I will post soon how to build that project using 18F2550 MCU, it will make you pull out your hair :D. Read the User input data from serial monitor then.Setup and initialize your serial communications.* each arduino connected to a text LCD to display the sent data as stars, ex(******) - this step is not important ,just for fun :D.ġ - Connect all the parts as Schematics below.Ģ - Starting with the Laptop Uno : Laptop Uno connected to the RF transmitter part and the PC Uno connected to the Receiver. * Arduino Uno attached to laptop and another for the PC.

I need to send some data form my laptop serial monitor (embedded tool with arduino IDE) to my PC and receive the data on Arduino IDE serial monitor, so we need: Your code, posted as I requested in reply #1: #include įloat c1 = 1.009249522e-03, c2 = 2.378405444e-04, c3 = 2.This project is a good tutorial on sending data using Cheap RF module without dumping the data. Code tags can also be inserted manually in the forum text using the code and /code metatags. Highlight your code by selecting it (it turns blue), and then click on the '' icon at the upper left hand corner. If you have already posted without using code tags, open your message and select 'modify' from the pull down menu labelled, 'More', at the lower right corner of the message. The 'Code: ' feature allows someone to select the entire sketch so it can be easily copied and pasted into the IDE for testing. Also, if you don't do it, some of the character sequences in the code can be misinterpred by the forum code as italics or funny emoticons.

It makes it easier to read, and can be copied with a single mouse click. The code tags make the code look like this In this case, the problem is that you have posted code without using code tags. Making an effort to do this will greatly increase the number and quality of helpful responses that you get. The forum link above has guidelines for posting in a standard way that makes it easiest for people to provide you with useful answers. It is important to provide as much of the information that is needed to solve your problem as you can, in your first posts.
