The microcontroller simulator is designed to teach the basics of microcontroller hardware and software.
The simulator can be used to demonstrate various devices interacting with the microcontroller.
It is able to create a test point to investigate the time sequence of writing or reading data to the microcontroller when accessing another device. Research can be done with a logic probe or logic analyzer.
Each peripheral unit is equipped with a two-position switch with peripheral selection capability.
It is easy to load program files into the microcontroller and does not require any special software.
The modules are equipped with overvoltage and overcurrent protection to protect the module from possible damage.
The system consists of modular blocks, which allows students to learn the microcontroller in a modular fashion. Panel-type structures are convenient for conducting experiments.
All inputs and outputs on each panel have rugged 4-mm jacks for easy connection.
A complete step-by-step guide to the experiments is included.
