Concept
A comparator + flip-flop charges/discharges a capacitor through resistors.
A little theory
Astable f ≈ 1.44 / ((R1+2R2)C). Monostable pulse T = 1.1 RC. In the classroom, treat NE555 Timer IC (DIP) + kit bits as a beginner part using Analog timer pins. Typical India street price is about ₹5–₹25. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project.
How it works in a project
Breadboard 8-pin DIP with two resistors + cap; LED on pin 3 via resistor.
