Arduino UNO R4 Lesson 05. Digital Inputs | Pull-up & Pull-down Resistors | if-else statements

Arduino UNO R4 Minima Ultimate Training Course

This is the 5th lesson of the Arduino UNO R4 Minima Ultimate Training Series. In this video, Joed Goh talks about how to read digital signals from Arduino UNO's digital pin. He explains how to properly implement a pull-up and a pull-down resistor and what ideal resistor value should be used when using push-button switches. He also discusses the use of if...else... conditional statements to perform decision making in your code. Where to buy?

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
