What is the full form of LDR sensor? 🤔💡

• Light Distribution Rollercoaster 🎢

• Light Dependent Resistor 🌞

• Light Detection Rainbow 🎨

• Light Digital Riddle 🧩

How can you fix the LDR sensor if it doesn’t see bright light? 🌞🔍

• Plug it into the magical analog pins! 🪄

• Switch it to a different digital pin for a fresh start! 💻

• Give its resistive screw a little twisty twist! 🔩

• Rewrite the code like a wizard! ✍️

All the sensors are... 🤖🔍

• Input devices that gather information from the environment! 🌎

• Output devices that just print words! 🖨️

• Input devices that tell stories! 📚

• Output devices that only blink lights! 💡

👀 Check out the code above! What number will be printed if the LDR sensor detects bright light?

• 0

• 1

• 255

• 1023

Where do we need to connect the VCC of the LDR on Arduino? 🔌

• Any analog pin 📏

• Any digital pin 💻

• Power pin - 5V ⚡

• GND pin ⬇️

Why do we need to connect a resistor to the photoresistor in Tinkercad connections? 🤔

• To help the photoresistor send messages 📡

• To limit the current and protect the photoresistor ⚡

• To help the photoresistor detect more light ☀️

• To turn the photoresistor into a super sensor 🦸‍♂️
