Concept
Resistors limit current (Ohm’s law: V = IR).
A little theory
LED: R ≈ (Vcc − Vf) / I. Pull-up 10 kΩ. Divider for ADC. In the classroom, treat Resistor Kit (1/4 W, E12 values) as a beginner part using Through-hole. Typical India street price is about ₹50–₹150. 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
Colour code or print. Combine series/parallel as needed.
Classroom & project use
- LED current limit
- ECHO level shift

Buying in India
Precautions
- 1/4 W — don’t dump motor current through them
- Share a common GND with the microcontroller
