Study Notes
Mechatronics is a multidisciplinary field of engineering that integrates mechanical, electrical, and software engineering. It often involves the design of mechatronic systems, which typically have embedded computers and require programming skills. To successfully work with these systems, one needs various tools, including the following:
Multimeter
A multimeter is a versatile tool used to measure electrical properties like resistance, voltage, amperage, frequency, capacitance, and temperature. It's essential when troubleshooting electronic circuits, testing power supplies, and debugging printed circuit boards.
How it Works
Multimeters function by converting physical quantities into a readable form through conversion factors. For example, they might convert a large AC voltage signal into a small DC voltage signal that can be measured on a scale called millivolts per volt (mV/V).
Oscilloscope
An oscilloscope is an instrument used to view changes in voltages over time. It has two main applications: finding out what an electronic system is doing, and generating periodic signals.
How it Works
Oscilloscopes capture, display, and analyze any waveform from DC to several GHz bandwidth. They allow engineers to see how fast something happens.
Microcontrollers
Microcontrollers are devices that combine an analog or digital computer on a single integrated circuit (IC) chip. These chips containently all three basic components: processor, memory, and input/output peripherals.
Types of Microcontrollers
Common types of microcontrollers include:
- Intel AVR series
- PIC microcontroller family
- Arduino microcontroller board
- TI MSP430 series
- PSoC (Programmable System on Chip) CY8CKIT series
- STM32 series
- Raspberry Pi
Using Microcontrollers
To use a microcontroller, you program its controller using the desired programming language, such as C, C++, Python, or even ladder logic. This allows you to control the device's behavior based on sensor inputs and perform actions accordingly.
Sensors
Sensors are devices that detect and respond to different types of energy, such as light, heat, motion, pressure, magnetic force, and more. Some common sensor types include:
- Accelerometers: Measure acceleration due to present movement or vibration
- Pressure sensors: Detect atmospheric pressure and other pressures relative to atmospheric pressure
- Humidity sensors: Monitor humidity levels in the environment
- Light sensors: Determine the intensity and wavelength of light
- Temperature sensors: Measure the temperature of objects or environments
- Proximity sensors: Detect proximity to nearby objects without physical contact
- Force sensors: Measure forces applied to them
Actuators
Actuators are devices that translate energy into controlled motion or force. Examples of actuators include solenoids, linear motors, servo motors, and stepper motors.
Controlling Actuators
Controlling actuators involves sending appropriate signals to their respective controllers. Depending on the type of actuator, this may involve setting specific motor parameters, sending signals to valves or pumps, or adjusting speed based on environmental conditions.
