Circuits with Counters and Timers

Basic Level

• 
  Practical case: astable oscillator with NE555
  Level: Basic — Build an NE555 astable timer that blinks an LED at a visible frequency.## Objective and use caseYou will build a simple astable timer with…
• 
  Practical case: One-Shot Timer Using NE555
  Level: Basic – Build a monostable timer circuit using the NE555 IC to control an LED output for a set duration.## Objective and use case In this practical…
• 
  Practical case: Frequency divider by 2, 4 and 8
  In this Digital Electronics lab, use a Binary counter to build a frequency divider. Verify square wave outputs at f/2, f/4, and f/8 relative to the clock.
• 
  Practical case: 4-bit up counter with LEDs
  Build a practical Digital Electronics circuit with a Binary counter. Visualize the 0 to 15 sequence on LEDs and verify synchronous clock signals.

Medium Level

• 
  Practical case: 0-9 counter with TTL-compatible reset
  Level: Medium — Build a decimal counter that advances from 0 to 9 and resets automatically using a TTL-compatible AND gate.## Objective and use caseYou…
• 
  Practical case: Conveyor belt object counter
  Level: Medium – Build an optical object counter with decimal outputs and an automatic batch reset.## Objective and use case In this practical case, you will…
