Electronics is a big part of the world today so engineers are becoming more and more important, they are import ants of them is increasing with every new invention.
Electronic systems comprising:
• Inputs (for example light or temperature sensors)
• Analogue and digital signals
• Process devices:
• Timers
• Counters
• Comparators
• Logic (AND, OR and NOT).
Programmable devices:
Microcontrollers and Interface controller (PIC) used to perform more complex operations or replace discrete process integrated circuits. Interfacing components: drivers required for loads that process or programmable devices cannot supply (transistor, field-effect transistor (FET). The use of analogue to digital conversion (ADC) in a programmable device. Output components:
• LEDs
• 7 segment display
• Buzzer
• Piezo sounder.
Discrete components within a circuit:
• Resistors (fixed and variable)
• Diodes (signal, rectifying)
• Capacitors (polarised and nonpolarised).
Simple programming for monitoring and controlling processes:
Using flow charts for explanation, limited to three inputs and three outputs within an engineered system.
