Arduino UNO R4 Lesson 07. Understanding Photoresistors | nested if, else-if, and for-loop

This is the 7th lesson of the Arduino UNO R4 - Ultimate Training Series. In this video, Joed Goh explains the use of photoresistors, also known as Light-Dependent Resistor (LDR), in creating a light-activated LED sequence project. He also explains how to use nested if, else-if, and for-loop statements.

still underrated, it's unacceptable. The quality of demos and explanations is incomparable. Thank you

Hi Joed, your lessons have been top class! Really enjoyed every lesson u put up so far. Hope to learn more from you thru this series. Thank u!

More power Sir Joed! I still learned a lot from this. 😊

I received my SunFounder Ultimate Sensor Kit the other day and my Photoresistor Module only has 3 pins (VCC, Ground & DO). Can I get an updated sigmatic and code to use?

I need some guidance. When I block light from hitting the photo resistor the voltage only reads 4.0000 volts (ADC 875). I would expect a voltage closer to 5V. When I shine a light on the photo resistor the voltage reads 20000 (ADC 602) I would expect a voltage closer to 0.7 V. Using the same sketch using the potentiometer module the Serial monitor returns a voltage from 0 to 5 V. as I would expect. I'm thinking I have a faulty photoresistor module. What else might be causing the unexpected readings?

Complimenti ❤ Bel corso ... Spero che farai molti video su Arduino. Quanti video sono previsti su questo corso ? Ha fatto anche dei corsi su piattaforma Udemy o scritto libri su Arduino ? Grazie

[mixme]

thank you sir Lesson 7 pa lang me Im late
