The Rise of Electronic Environment Our surroundings are becoming more electronic, with smart homes featuring intelligent appliances and lighting. This trend is making programming for embedded systems increasingly accessible.
Challenges in Early Development Early development was challenging due to the need for extensive knowledge of electronics, soldering skills, and low-level programming. Entry into this field required a high level of expertise.
Introduction to Microcontrollers Microcontrollers are small devices or computers that control other devices or mechanisms. They can be used as actuators and controllers in various applications.
Understanding Controllers and Actuators 'Controllers' refer to small devices or computers that manage other equipment while 'actuators' interact with sensors, instruments, mechanisms, etc., providing an overview on how they function together.
Overview of Embedded Systems Programming Embedded system programming involves developing software for integrated systems using microcontrollers. The course aims at practical learning rather than theoretical concepts.
Voltage Difference and Potential The voltage difference between two points is 10 volts, indicating a potential of 15 volts at one point. The concept of 'ground' as the reference point for electrical potential.
Current Flow and Ohm's Law Electric current flows from higher to lower potential, following Ohm's law where voltage equals current multiplied by resistance. Resistance affects the flow of electric current through a conductor.
Analogies with Water Flow Comparing electric current to water flow: Current strength is like water quantity flowing through an area in a unit time; resistance is similar to narrowness affecting water flow rate.
'Ground' Concept and Voltage Division 'Ground' serves as the zero-voltage reference point. Voltage division occurs when resistors are used in series circuits, resulting in different voltages across each resistor based on their values.
Understanding Resistors and Their Functionality 'Resistors provide voltage drop within a circuit, reducing input voltage while allowing output control.' They can be utilized for various purposes such as signal conditioning or power dissipation.
