Over at DesignSpark, Dr Lucy Rogers has written a great tutorial which fuses the Raspberry Pi, 3D printing, an ESP8266 module and some Neopixels into a bus warning system. The system has the following features:
- A visual alert to tell you to leave for the bus stop – and your bus will miraculously arrive just after you do.
- #WhereIsMyBus will also warn you if there are no buses running, so you can make other plans.
- And if that isn’t enough, when it is not in use as a bus alert, it becomes a #Cheerlights light.
It uses a combination of Arduino code and Lucy’s favourite language NodeRED. You can download all the files you need (including the 3D printing files for the bus itself) and read the tutorial here.
