Newcomer says hello

Just registered and want to say hello everybody. :slight_smile:

I got the UNO board together with some bits (4x20 LCD, SerLCD, Temp and Humidity sensors) today.

Some years ago I started to build terrarium controller from scratch. It should have been based on Atmel 8088 micro controller. I built a serial port programmer for the chip and all PCBs. I did not finish it then. Wanted to finish it recently and searched for some USB programmer that could be used with my new MAC. Also I did not want to go back to assembler language again and wanted some higher level language. Found some solutions but Arduino really stood out. It looks like the board can give me much more fun then one purpose board plus I would be able to debug my project more easily.

The controller should be able to control temperature on various spots in the tank, humidity, lights with real time clock. It should be able to operate more then one terrarium. I guess it is pretty big project for me. :slight_smile:

Anyway, nice to be here and I hope for lot of guidance with my project. :smiley:

Welcome, and good luck with your project. Have to get yourself a real time clock chip like DS1307. Can be had inexpensively here

One Uno controlling reading multiple sensors and controlling multiple heaters, lights, etc per tank and multiple tanks may need some external chips as well for multiplexing your inputs & outputs.

Thank you. I think I can use something like this for multiplexer:

Also there are one wire temp sensors available:

I still have the Dallas I2C real time clock chip somewhere in the drawer.
