C and C++ Linux/Unix
This set of notes does have some prerequisites. It requires two important sets of knowledge:
- You must know how to use the command line for your OS, either Terminal
(Mac, Unix) or cmd/DOS (Windows).
Here is a tutorial for Macs
Here is one for Linux (Ubuntu)
Here is one for Windows - You must know how to program, preferrably in C.
The fact is, most microcontrollers are programmed in C, its a lightweight programming language that is well suited to the restrictive environment. You can also do many of these examples in BASIC but I doubt I'll have time to put up those versions
Here is a tutorial
I learned C about 12 years ago from a book that came with a CD and had lots of examples, I think it was "Learn C in 21 days" or some nonsense. It doesn't matter how you do it, but this tutorial assumes that you know what a for loop is and how bit-wise arithmetic work, etc.
You also need to be able to convert hex, binary and decimal (using a calculator).
Microcontrollers are tougher to program because there is limited debugging capability.

DS18B20 Temperature IC $3.00
The DS18S20 Digital thermometer provides 9-bit centigrade temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18S20 communicates over a 1-Wire® bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C. In addition, the DS18S20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.
Each DS18S20 has a unique 64-bit serial code, which allows multiple DS18S20s to function on the same 1-Wire bus; thus, it is simple to use one microprocessor to control many DS18S20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment or machinery, and process monitoring and control systems.
