Raspberry Pi with Node-RED Tutorial #4 - interacting with Arduino UNO

Node-RED interacting with Arduino UNO You can interact between Node-RED and the Arduino board via Raspberry very easy. Install the Arduino IDE and Arduino Nodes and you can handle any hardware on Arduino side via Web-browser. ********** Attention !!!! ************** If you have a newer OS version like (2017-01-11-raspbian-jessie) you need to upgrade node.js and the Node-RED before you started the steps in the video! So after the first boot you need to do the following step at first: 1. sudo apt-get update 2. sudo apt-get upgrade 3. sudo reboot 4. update-nodejs-and-nodered 5. sudo reboot 6. Then you can start to install the Arduino IDE and following the steps like in the video…. If you would like to change the sampling rate than do it in the StandardFirmdata in the Arduino IDE: https://pbs.twimg.com/media/DObOCkFW4...
