Arduino UNO R4 Lesson 04. Variables, Data Types, and Constants | Arduino Ultimate Training Course

Arduino UNO R4 Minima Ultimate Training Course

This is the 4th lesson of the Arduino UNO R4 Minima Ultimate Training Series. In this video, Joed Goh talks about variables, data types, constants, and macro definitions (#define preprocessor directive). He explains the correct use of variables, constants, and macro definitions when programming microcontrollers with limited memory resources. In his illustrations, he uses the SunFounder's LED traffic light module included in the kit. 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
