This beginner-friendly guide is designed for 5th graders and above, introducing students to the basics of programming and physical computing using an Arduino board. Follow step-by-step instructions to create your first LED blink project, learn to communicate with your computer using serial input and output, and solve a coding challenge to reinforce your understanding. Start your journey into the fascinating realm of coding and electronics today! selfAssign: true defaultNumberOfRooms: 0 id: 79sFHo6ONB1S25cTN7emXmOibQ2HNWb2G9X3Xn2x members: teacher: [] student: [] modules: - url: https://edrys-labs.github.io/module-markdown-it/index.html config: content: > ### Introduction to Arduino and Physical Computing **What is Arduino?** Arduino is a popular open-source platform used for building electronics projects. It consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment), which runs on your computer. You use this software to write and upload computer code to the physical board. **What is Physical Computing?** Physical computing involves designing and building interactive physical systems through the use of software and hardware that can sense and respond to the world around them. With Arduino, you can read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. studentConfig: content: '' teacherConfig: content: >- ## Welcome for Teachers > This can be used as a base laboratory to create further and more elaborate labs with [edrys-Lite](https://edrys-labs.github.io). > You are currently in the Lobby. If there is a station available you can switch to it and try out the terminal. > Otherwise, if you are in teacher-mode you can share a lab by clicking onto `setting` >> `station` and then by clicking the presented link, > which is the same as the current link, but only with the word `station` instead of `classroom`. stationConfig: content: '' showInCustom: lobby width: full height: huge - url: https://edrys-labs.github.io/module-blockly-duino-v2/index.html config: runCommand: execute board: arduino_mega studentConfig: '' teacherConfig: '' stationConfig: '' showInCustom: station width: full height: huge - url: https://edrys-labs.github.io/module-markdown-it/index.html config: content: >- # Arduino Tutorial ## Step 1: Your First Project - The Blinking LED **Objective**: To make an LED blink on and off every second. 1. **Program Your Arduino**: - Open your Arduino IDE. - Modify your Blockduino, so that it looks like the following code: ![Blink example](https://raw.githubusercontent.com/edrys-labs/lab-arduino-basics/main/media/blink.png) - Click on the "Run Code" button to send your code to the Arduino. 2. **See the Magic**: Once uploaded, the LED on your breadboard should start blinking. ## Step 2: Adding Serial Communication **Objective**: To control the LED blinking with a command from your computer. 1. **Modify Your Code**: - Add the following to enable serial communication: ![Serial Communication](https://raw.githubusercontent.com/edrys-labs/lab-arduino-basics/main/media/serial.png) 2. **Test Your Setup**: - Open the Serial Monitor in the Arduino IDE. - Type `1` to turn the LED on and `0` to turn it off. ### Wrap-Up Congratulations! You have successfully completed the Arduino blink tutorial, mastered basic serial communication. Now, you're ready to explore more complex projects and dive deeper into the world of physical computing! studentConfig: content: '' teacherConfig: content: '' stationConfig: content: >- ## Instructions for Station-Sharing You are currently responsible for sharing a station of this lab. You have multiple options to share a or your terminal. Therefor we use the pyxtermjs - terminal server from: https://github.com/edrys-labs/module-pyxtermjs ### Using Docker If you haven't done it so far, install [docker](https://docs.docker.com/engine/install/). Or, follow one of the instruction-videos for your system:
Install Docker on Linux
Install Docker on Windows
Install Docker on MacOS
Then the only thing that is required is to run the following command: ```bash docker run -it -p 5000:5000 --device=/dev/ttyACM0:/dev/ttyACM0 edrys-labs/pyxterm-server:latest ``` This will download the pyxtermjs terminal-server from docker-hub and run it in a secure environment. ### Using Python You can also share your terminal directly via Python, visit the following project https://github.com/edrys-labs/module-pyxtermjs/tree/feat/trzsz ... the easiest way is to perform the following steps: ``` bash # 1. clone the repository or download the folder manually git clone https://github.com/edrys-labs/module-pyxtermjs/tree/feat/trzsz # 2. install all required sources pip3 install -r requirements.txt # 3. run the terminal-server python3 -m pyxtermjs --cors True --command bash --port 5000 ``` showInCustom: station width: full height: huge - url: https://edrys-labs.github.io/module-station-stream/index.html stationConfig: video: true audio: false showInCustom: station width: half height: medium - url: https://module-pyxtermjs.netlify.app/ stationConfig: server: http://localhost:5000/pty execute: execute script: > echo $CODE | base64 --decode > Blink.ino arduino-cli sketch new Blink olddir=$(pwd) mv Blink.ino Blink cd Blink arduino-cli board attach -p /dev/ttyACM0 -b arduino:avr:uno cd $olddir arduino-cli compile Blink && arduino-cli upload -p /dev/ttyACM0 Blink && arduino-cli monitor -p /dev/ttyACM0 enable: teacher: true student: true showInCustom: station width: half height: medium
