Lowa posted a topic in LEGO Train TechThis is a control panel made with our button controls. It controls a decoupler, two boom barriers, a track switch and a traffic light. The buttons interconnect and each button is powered by the previous button, the first button is powered by a power brick. The goal is to be able to automate all aspects of your LEGO train layout. It's inspired by the vintage 12V system but designed for PF and 9V track. We're planning on launching a campaign for these button controls on Kickstarter later this month. Decoupler is 3D printed and PF track compatible. It decouples the train by blocking the wheels of the cars that have to be decoupled. It's powered by a servo motor. The boom barriers are made with a small servo motors, they measure 2 x 4 x 3+1/3. Let us know what you think!
We just finalized our button control for train traffic lights. It’s part of a range of buttons we're developing to control your LEGO train layout with a physical control panel. The outside is identical to the track switch motor button control we presented a while ago but inside it has a driver for traffic lights. It’s more than a simple light switch, this button control also supports a number of blinking effects. The two indicator LEDs on the button control mimic the behavior of the traffic light so you can see the current state of your layout on your control panel. The button control can also be reconfigured to be used as crossing barrier light controller: right button = lights off, left button = both LEDs blinking. The next step are button controls for boom barrier and the decoupler track. Let us know what you think!
I'm programming my EV3 vehicle to be operated by an IR beacon remote. I've successfully got the car to be able to move, but I'm stuck on something else. My vehicle has a 4-speed transmission, and a medium motor shifts the gears. I used the remote's topmost button (the one that turns on the green light on the remote) for shifting the gearbox. But when I press it, something goes off. It's really hard to say, but what I know is that the topmost button isn't acting like a normal button. So the motor keeps on moving until the IR sensor realizes the green light is off. I really need help with the program because I just want the topmost button to act like a normal button so I can press it to make the medium motor shift one gear with a one second wait before shifting to the next one. I would love a very helpful response from someone that knows how to program the IR remote and if there is no way to get the topmost button to get the result I want, an alternative would be nice so I can be able to shift gears with the push of a button on the remote.
