I am new to Arduino, and I am already impressed and excited.
My questions is, am I able to build a unit that measures and displays speed, water/coolant temperature, and lap times including Split Times based on 1 or more (split times) magnetic strips built into a race track. There are units available for purchase for example, Mychron 4, Alfano, however, I want to build/design my own.
If it is possible, what will I need hardware wise?
I am hoping to use a color screen of some sort, possibly touch screen, otherwise, I will need some buttons to skip through different options.
I want my unit to display Speed (0-200kph), RPM (0-20000rpm), Water Temperature ( 0-100 Celsius), Lap Times eg: 42.056 seconds. I possibly want to be able to enter different settings based on which track i go to..SELECT TRACK 1 - 3 magnetic strips or TRACK 2 - 2 Magnetic Strips. Id also want the option to display the following, not all at the same time, these options could be seen/flicked through after a race etc: Driver Name Date Time Last Lap Fastest Lap/s Speed
What are my options? Would a gps unit be the best way to get a speed reading? How can I get the RPM reading? All i really want for now is a list of hardware capable of running and recording this data.
At present as an example, I run a Mychron 4, the speed pick up is through a magnet stuck to my axle, and the sensor mounted just off the axle. The temperature is read through a 2 wire temp sensor that is bolted into my engine cylinder head, the RPM pick up is a single wire that wraps around my ignition/spark plug lead and the lap times are gathered through a magnetic pick up (I believe this is a reed switch) which is mounted to the floor pan of the kart.
Any help would be greatly appreciated! I have read the terms and conditions of posting, and assure you I have tried my hardest to adhere to the rules, and hope I have not too much or not enough information.
