Concept
Remote blinks 38 kHz IR; VS1838 strips the carrier and outputs a NEC/Sony bitstream.
A little theory
IRremote library decodes pulse widths. OUT is active LOW bursts. In the classroom, treat IR Remote + VS1838B Receiver as a beginner part using 38 kHz IR demodulated digital. Typical India street price is about ₹50–₹120. 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. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
How it works in a project
Vs1838: OUT to a digital pin, IRrecv, map hex codes to actions.
Classroom & project use
- Robot remote
- Slide clicker
- TV-off prank (don’t)
Buying in India
Precautions
- Share a common GND with the microcontroller
