![]() ![]() If students are working on projects over several lessons, then storage for partially completed projects will be necessary as well. Storage will be necessary for the kits.It’s nice to have a projector attached to the teacher’s computer to display the software and activities while teaching.The LEGO Education WeDo Software is available to download here. Although fewer computers would be manageable, one computer per group is best. The WeDo software contains programming software and a set of activities that include engaging video, step by step building instructions, and guidance for programming. So, for a class of 30 students, plan on 16 kits, including one kit for the teacher. This gives students the chance to actively participate in building and programming and promotes collaboration, while limiting idle time. Generally, it is best to have one kit for every two students. The roughly 150 pieces in the kit includes two sensors (tilt and motion), a motor, and a USB hub. The WeDo kit comes in a stackable, white plastic container. For a guide to LEGO Education WeDo 2.0, see What to buy (WeDo 2.0). Although the classic version of LEGO WeDo is no longer sold by LEGO Education, it might still be available from third parties. Note: This guide is for the classic version of LEGO WeDo, which comes in a white container. In my case, for coordination of multiple devices/trains, I think the stock firmware works best, using a central computer for control.Planning on introducing the WeDo into your class? Below are some ideas on what you need to get started. I do like the idea for Pybricks, but I think it excels for standalone builds that don't require a computer to control. For sensors, switches, signals etc, I prefer wires. I also like your idea of powering via the track, but I prefer pure Lego solutions that don't require modifications. Personally I only want to use batteries if the model is moving, such as a train. ![]() I also don't mind cables - they provide full power instead of requiring batteries, and if I were to build a properly build layout, I would hide the cables underneath Lego plates or something else. I hope they come out with a hub type that allows power to be supplied via a cable - even better if it could be controlled over the cable as well as Bluetooth. ) However I think it requires older Lego products - newer Powered Up products don't have a good solution for power/energy. We'll have to disagree there, I think I proved it above. I think that is not possible to have a definitive solution with only LEGO products that offer a flexibility of power energy, communication and programming. Go back to step 1 for the other track/train. Train slowly comes to a stop in front of the red signal. On the third loop, as the train passes the signal, it is set back to red. Train is slowly sped up until predefined max speed. The WeDo's are plugged straight in via USB, the Control Lab has a RS232 to USB converter cable. MacBook Pro running the Node.js/Typescript code that powers this, utilizing some libraries I've written and open sourced. ![]() Lego Powered Up hub and Lego Control+ Medium motor powering the Crocodile 10277. The second hub powers the "near" side, and does the opposite. The first hub powers the "Far away" side, and is used to detect trains approaching one side, while detecting trains at the end of the other side. There are two hubs, each with two distance/motion sensors attached. One of the switch motors is on port E, the other is on port F. Each light is a Power Functions LED (the second bulb is hidden inside the control box beside the signal). The second signal has red on port C, and green on port D. The first signal has red on port A, and green on port B. The distance/motion sensor is also identical to the Powered Up/LPF2 one, offering infrared distance detection.īelow are a couple of videos of the setup working, but here's the breakdown. WeDo hubs plug straight into USB, allowing constant power and no battery issues. I hope Lego offer some kind of mains/USB power option for the Powered Up hubs. Powered Up/LPF2 motion/distance sensors would work, but other than the SPIKE Prime hub, have no constant power solution at the moment - only batteries. I might still try this in the future though. I decided to use WeDo (1.0) sensors for train detection for a couple of reasons.ĩv light sensors plugged into the Control Lab could work, but are susceptible to changes in environmental light. :) In the process, I added a new piece of Lego technology to the mix - Lego Education WeDo (1.0) hubs and sensors. Following on from my previous topic about combining old and new Lego technologies, I decided to take it a step further and automate the trains. ![]()
