    As part of my efforts in STEM outreach, I recently ran a workshop for Year 9 and 10 IT students at a local high school. I wanted to present something that would be interesting and different from what they would normally have from their school classes so I settled on doing a simple IoT demonstration involving Raspberry Pi, Sense-HAT, and Node-RED. The Raspberry Pi is a great way to introduce students to computing and electronics engineering. The students I was presenting to had little or no programming experience so a visual system such as Node-RED enabled them to program simple tasks. Within 5 minutes of me presenting them the basics of Node-RED, they were quite comfortable using Node-RED and modifying the examples that I gave them. The workshop exercise was to extract sensor data (accelerometer, temperature, humidity, etc) and send it to an IoT platform. They could then view the data that was sent in a web browser in real time. Since we were using accelerometers, I encouraged the students to move the Raspberry Pi around while viewing the graph on the IoT platform to see how the values changed. I think having a computing system with physical sensors providing real time feedback made the workshop more interesting than just a programming exercise on a computer. The students seemed to enjoy it and I got a lot out of seeing their enthusiasm. IoT demonstrations are a great way to get the next generation interested in building things.
