This is a short follow-up post to the last one. I’ve named my project RATTY. Trying to mount 5 buttons within easy reach of the driver turned out to be a difficult problem to solve. So instead, I decided I could get away with a single button if I used a combination of clicking styles. I put the button on the gear shifter. I think the steering wheel would be a good place too.
I’m planning on using this as follows:
- Single-click: “Yes”
- Double-click: “No”
- Multi-click: “Bad stuff has happened”
- Long-click: “Pit request”
Here I am interacting with RATTY from the comfort of my desk. This is the output as it looks on my iPhone 6S Plus. I set the font slightly larger as the default is pretty small.
Here’s a link to the ratty GitHub repository where you can get the code if you want to build one yourself. I’m using an Arduino Uno WiFi R2, but I think you could use an Arduino Nano 33 IOT, which is about half the price ($22.55 with tax and shipping). I have one on order to build a second unit. A HotSpot will cost around $100, but you could use a phone instead.
The next step is to mount everything in the car.
