Learn how analogRead() works in Arduino and how sensors send real-world data to your program 💡
In this video, you’ll understand:
- What is analog input (0–1023)
- How Arduino reads sensor values using analogRead function
- Difference between analogRead and digitalRead
- How to convert sensor input voltages to (0-1023) 1024 steps or levels
- Arduino UNO 10 bit ADC
This is one of the most important concepts in Arduino programming — once you understand this, you can build smarter projects using sensors like LDR, potentiometer, and more 🚀
Perfect for beginners and intermediate learners.
