How do flip-flops count clock pulses in binary and divide a frequency?

Counters: chaining flip-flops to count clock pulses in binary, frequency division by each stage, and the modulus of a counter.
An Eduqas GCSE Electronics answer on counters: how chained flip-flops count clock pulses in binary, how each stage divides the frequency by two, the modulus (number of states) of a counter, and using counters to divide frequency and count events.

How does a flip-flop store a single bit, and how is it different from a combinational circuit?

Flip-flops and latches: storing one bit, the difference between sequential and combinational logic, the D-type flip-flop, and edge triggering by a clock.
An Eduqas GCSE Electronics answer on flip-flops and latches: how a flip-flop stores a single bit, the difference between sequential and combinational logic, the D-type flip-flop and how it captures its input on a clock edge, and using flip-flops as memory and to divide frequency.

How are the input, process and output subsystems interfaced into a complete working electronic system?

Interfacing and system design: matching analogue and digital subsystems, signal conditioning between stages, and designing and testing a complete input-process-output system.
An Eduqas GCSE Electronics answer on interfacing and system design: matching analogue and digital subsystems, conditioning a signal between stages so it suits the next block, driving real output transducers, and designing and testing a complete input-process-output system.

How does a microcontroller control an electronic system, and how is its program planned with a flowchart?

Microcontrollers: the microcontroller as a programmable processing subsystem, inputs and outputs, and planning a control program with a flowchart.
An Eduqas GCSE Electronics answer on microcontrollers: the microcontroller as a programmable processing subsystem with input and output pins, the advantages of programming over fixed logic, and planning a control program with a flowchart using the standard symbols.

How is a binary count turned into a readable decimal digit on a seven-segment display?

Seven-segment displays and decoders: the seven-segment display, the decoder that drives it from a binary count, and common-anode and common-cathode types with current-limiting resistors.
An Eduqas GCSE Electronics answer on seven-segment displays and decoders: how a seven-segment display forms digits, the decoder that converts a binary count into the segment pattern, common-anode and common-cathode types, and the current-limiting resistor each segment needs.
