Serial Port Multiplexer Arduino

Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to share a very basic and introductory tutorial named as How to use Arduino Serial Read. I am sharing this tutorial because I am getting a lot of emails in which users normally asks about basic Arduino tutorials as they are very new to it. So, I thought of sharing this very basic Arduino tutorial in which we are gonna have a look at how we can use Arduino Serial Read command.I selected this tutorial as my first tutorial in this list of Arduino basic tutorials because learning to use Serial port is very necessary as its one of the best troubleshooting tool for your code. I know things are looking bit complex here but I have explained each and everything below in detail so don’t you worry.

Just read it once in complete so that you get all the tiny details of this Arduino Serial Read. I have also given a Proteus Simulation in which I have received the incoming data from serial port and displayed it on LCD. Before going into the details of this Arduino Serial Read, let me first discuss the Serial Port in General.

There are two methods of doing what you want:. Add more ADC channels. Multiplex the existing ADC channelsSPI or I2C ADC chips are readily available in a range of resolutions, sampling speeds and number of channels.

They are fairly simple to add to any Arduino.For instance the MCP3208 will give 8 channels of 12-bit resolution on SPI, which means 3 pins (MOSI/MISO/SCK) + 1 per chip (SS). I have been exactly working with the same Issue. I need a program that reads 100 Thermistors.Why?

Well, some times you need it.I kinda finished that already.I tried the 74HC4051 multiplexer / demultiplexer. But, for some reason I didn't get the desired result.First thing you will find.POWER, you will need an external power supply, in my case I just made a voltage divider and connected the thermistor to that power, then just use the Analog port for reading.I use I2C protocol, 8 arduino Mega 7 slaves and One master. And since send send Integer, float, and blah, blah was kinda not helping I just made it for It can send the Analog reading over I2C and the master makes all the desired conversion.If you still are interested, I can send you the source code for master and slaves. With this template you can connect up to 50 arduinos and the master will look for every arduino connected in the network and ask for data.Regards.
