Lab 1: Building a Burglar Alarm System
Microcontrollers are elements that fall between electronic hardware and software. They are computers in that they are programmed using algorithmic languages, but they are hardware in that they are installed by being wired into the system with all of the other electronic components. In the first project, we take our first step into the hardware domain by interfacing our first few electronic components: LED’s, pushbuttons, seven-segment displays, LCD display, etc., and initiating interaction with our microcontroller. By completing these exercises, we can then integrate these devices to build a burglar alarm system
|Lab 2: Building a Digital Multimeter
physical world remains fundamentally analog while the computer is
primarily a digital device. Hence, conversion between analog and digital
domains, appropriately termed Analog to Digital Conversion (ADC) and
Digital to Analog Conversion (DAC), is essential to permit operation by
computers on the physical world, and this second project focuses primarily
on such conversions. For example, sensors typically output an analog
signal (voltage or resistance) proportional to the quantity being
measured; and actuator outputs are designed to be proportional to analog
control signals (voltage/current), which must be provided by the computer.
To motivate and understand this process, we will be implementing the
|Lab 3: Speed Control of DC Motor
|One principal area that has seen a tremendous increase in use of microcontrollers and digital control is industrial process control. The primary reason for this popularity is the tremendous flexibility offered by such a system to implement a variety of control laws coupled with the flexibility of changing these control laws on the fly. Hence, in this lab we will investigate one such implementation using the “Speed control of a DC Motor” as the central example.
