Whilst I am waiting for the DC motor to arrive that I'll be using on the Smiths speedometer project I thought I would see what else I can use the Arduino for.
Although I'll be running the R1 clocks mounted behind the steering wheel, I also thought it would be quite cool to convert a standard looking Smiths 52mm gauge into a gear indicator. Normally these sorts of things can be picked up on eBay for £15 but they are ugly and wouldn't work with my interior.
The sketch (code)
Ok firstly I am not a software developer so my code isn't going to be pretty. I have done my best to comment throughout and I have used the best logic I could come up with to get it working.
Feel free to modify and use as you wish. I link back to the blog would be appreciated.
