Raspberry Pi

RPi Node-Red: Push Button + BuzzerGoal: The push-button, RGB-LED, and buzzer lessons have all presented input and output separately, but in this lesson we'll be combining them for the first time. Composing input with output and vice-versa is one of the things that makes node-red so powerful! What you will learn: How to link Input (Push-button) with output (Buzzer) using node-red. Also how the buzzer and button can be wired to the pi at the same time.

RPi Node-Red: Connecting and Configuring an OLED ModuleGoal: Connect and configure an OLED module to display information What you will learn: How to connect an OLED module that uses an SDA and SCL communication protocol. What you will need: - Raspberry Pi - OLED module - Jumper cables

RPi Node-Red: Car Kit AssemblyGoal: Assemble a Rpi Car from the parts kit What you will learn: Special considerations for connecting sensors and screens, and how all the parts go together. What you will need: Full RPi car kit

RPi Node-Red: BuzzerGoal: Use node-red to output onto the GPIO pins to make a piezoelectric buzzer go off. What will you learn: How to output onto the GPIO pins using node-red, and how a piezoelectric buzzer works.

RPi Node-Red: RGB LEDGoal: Introduce the power and utility of the raspberry pi's GPIO pins by using them to control a RGB LED Module. What you will learn: What is a GPIO pin and how does it work, how does it relate to node-red. The technical steps of wiring the LED module to your rpi, and getting the software to interact with the hardware.

RPi Node-Red: Push ButtonGoal: You can use the GPIO pins can be used for output, like making the RGB Module change colors, but most of the time you will using them as in input device. Sensors like the BME-280 can send data about weather, or a sonic sensor can tell you how close something is. However the simplest possible sensor is a button that simply reports on or off. The goal of this lesson is to learn how to start using node-red to receive input through the GPIO pins. What you will learn: How to read the state of a push-button wired to the GPIO pins through node-red.

RPi Node-Red: Ultrasonic Distance Sensor (HC-SR04)Goal: Read distance measurements from the sonic sensor within Node-Red What You Will Learn: How the ultrasonic sensor is wired and how it can be programmed.

RPi Node-Red: CameraGoal: Install the Raspberry Pi camera and take a picture using node-red What you will learn: How to install a Raspberry pi camera, and how to configure the node-red camera node to actually produce images.

RPi Node-Red: PIR Motion SensorGoal: Setup a PIR motion sensor and read its output in node-red What you will learn: What is a PIR motion sensor, how it's wired to a raspberry pi, and how to setup node-red to read its output.
