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

Arduino UNO R4 Minima Ultimate Training Course

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. =========================================================================== ---------------------------------------------------------- Where to buy? ---------------------------------------------------- SunFounder Official Website: https://www.sunfounder.com/?ref=hmqmlw0e SunFounder Ultimate Sensor Kit with Original Arduino Uno R4 Minima https://www.sunfounder.com/products/sunfounder-ultimate-sensor-kit-with-original-arduino-uno-r4-minima?ref=hmqmlw0e SunFounder 3 in 1 Ultimate Starter Kit with Original Arduino Uno R4 Minima https://www.sunfounder.com/products/sunfounder-3-in-1-ultimate-starter-kit-with-original-arduino-uno-r4-minima?ref=hmqmlw0e SunFounder Elite Explorer Kit with Original Arduino Uno R4 WiFi https://www.sunfounder.com/products/sunfounder-elite-explorer-kit-with-official-arduino-uno-r4-wifi?ref=hmqmlw0e Amazon US SunFounder Ultimate Sensor Kit with Original Arduino Uno R4 Minima - https://amzn.to/3FCX06P SunFounder Ultimate Starter Kit with Original Arduino Uno R4 Minima - https://amzn.to/3MqfSKd ========================================================================== ------------------------------------------------------------------------------------------------------------------ TABLE OF CONTENTS 00:00 Introduction 02:05 Materials 03:09 How Photoresistors work? 05:37 Photoresistors in a Voltage Divider Circuit 09:01 Axel Benz Formula 11:46 SunFounder Photoresistor Module 15:23 For-Loop 17:29 nested if conditions 22:51 else-if statement 26:48 Challenge Activity 27:51 Up Next ------------------------------------------------------------------------------------------------------------------ Refresh Voltage Divider Circuit with: Lesson03.

About the course

What can you expect from this Course? In this Arduino UNO R4 Ultimate Training Series, I’ll be taking you from absolute beginner to Arduino master. You’ll learn how to work with a bunch of sensors like ultrasonic, gas and smoke, flame, vibration, accelerometer & Gyroscope, photoresistor, potentiometer, IR obstacle avoidance, Capacitive Soil moisture, Raindrop detection, Temperature, humidity, and pressure, PIR motion, Pulse oximeter & heart rate, Real-time clock, touch, IR speed module, joystick, and Time of Flight micro-LIDAR distance sensors. You’ll learn how to work with different displays like RGB LED, Traffic Light, OLED Display, and a 16x2 I2C LCD Display. You'll learn to work with a couple of actuators like TT motor, Servo, Centrifugal Pump, Passive Buzzer, and Relay. Finally, we’ll integrate different IoT communication modules such as the ESP-01 Wi-Fi module and JDY-31 Bluetooth module, to support several of our IoT projects to be made. Our primary goal is to assist beginners in their Arduino adventure. Since the Arduino UNO R4 is new to the market, there's a noticeable gap in instructional videos specifically tailored for this board, and we're here to fill that void. Many beginners find themselves unsure of where to start, and we aim to be the guiding light, making this series a comprehensive resource for anyone taking their first steps into the exciting world of Arduino programming. Our hope is that this series truly becomes a helping hand for beginners. #SunFounder #Arduino
