Control systems can be designed directly from logic gates or can be programmed into a microcontroller board such as the Arduino. These boards contain EEPROM (Electrically Erasable Programmable Read-Only Memory). This memory is non-volatile, which means that the program stays in the memory even when power to the board is removed. In this lesson, you will be designing a control system that monitors a toxic medical waste disposal plant. You will design the system first using logic gates, and then you will work with a design that contains an Arduino “sketch” (another name for a computer program) to accomplish the same thing as was done with logic gates. If you have never done any programming, the latter approach will also introduce you to programming a controller using a language that is similar to C/C++.
