Adding Python to your Node-RED arsenal lets you create easy Raspberry Pi robotic and IoT projects.
If you want to build some fun Pi projects but are still working on your Python skills, then mixing low-code Node-RED with Python might be an option for you. Node-RED [1] is a low-code drag-and-drop interface that is extremely powerful for the creation of Raspberry Pi robotic and Internet of Things (IoT) projects.
Node-RED's custom scripting is JavaScript; however, you can also use Python, which offers a platform to play and learn Python basics for high-level tasks such as scheduling and web dashboards while taking advantage of Node-RED's low-code interface.
In many cases, Raspberry Pi features are only available in Python, so even die-hard Node-RED users could benefit from knowing how to integrate Python into their projects. In this article, I look at two examples that mix Python and Node-RED. The first creates a web dashboard to drive a Raspberry Pi rover; the entire project only requires two Node-RED widgets. The second project creates an IoT page that shows temperature and humidity data from a BME280 sensor.
