I could use the internal EEPROM or add a SD card interface I haven't done this yet, but long term I'd like to save and load collections of waypoints as routes. The user interface should allow me to set waypoints, navigate between waypoints, and clear all waypoints.

Then based on my speed, I could show how much time it will take to get back home. The display should show the total distance back to home (accumulated from the current location through each previous location). Seeedstudio 2.8' TFT Touch Shield (v1.0, but they have newer versions now)Īt a minimum, I wanted to see my current location and be able to log waypoint locations at major turns along the hike. However, the source code may be very beneficial to you if you're working on your own GPS project.

This is a project I completed earlier this year, so I don't have good step by step instructions. They have so many visitors in Pagosa Springs from Texas, the gas station actually stocks Big Red! Sure there are a wide variety of GPS receivers on the market, but why buy one of them when I could make my own with an Arduino! (Also I've used some of the other GPS receivers, and their user interfaces are awful.) There are maps, but they're horrible - my wife and I are convinced its Coloradans sick joke to get Texans lost in the mountains. On some of the hikes we get a bit adventurous (and the trails are poorly marked), so I wanted to have a GPS receiver on hand just in case. My wife and I have been making an annual summer trip to Colorado to get out of the Texas heat.
