Arduino Gps Speed Indicator
- A project that can be used to determine the speed of a vehicle, for example a bicycle or another means of motorized locomotion. An easy project for beginners.
Supplies

- Arduino Nano
- GPS Neo 6M module
- ST7735 TFT Display
- Push Button
- Visuino software
- Arduino IDE
Schematic Diagram
- The electrical scheme is quite simple. The hardest part is connecting the display pins to the Arduino Nano board. Carefully check the scheme before the first use!
The Code
- The code is built with the help of the Visuino utility, a program that can help you create a code for Arduino with just a few mouse clicks. You can install the program, it is free up to 20 components or you can generate a license key for 15 days. The code is simple, the Visuino software generates a lot of information at the output of the GPS mode. Number of satellites, longitude, latitude, time, speed. The speed will have to support some simple multiplication and division operations in order to be displayed in km/h or mp/h.

Verification and Assembly
- During assembly, care will be taken with the connections of the display and the strict observance of the electrical scheme. Also, care will be taken that the antenna of the GPS mode does not have a clear view of the sky. In the final version, you can mount the device in a small box, powered by batteries
Start the Device
- Careful! If you use the device while driving a vehicle, make sure it is placed in a place that will not distract you from traffic rules!
- We turn on the device and wait 15-20 seconds until the satellite symbol stops flashing. At the same time, the LED on the GPS module will blink with a frequency of about 1 blink per second.
- Longitude, latitude, clock (which is very accurate), travel speed will appear on the screen.
When pressing the button, the speed information will be displayed in km/h or mph
The location of the antenna must be chosen in such a way that visibility to the sky is ensured at all times. If you have more detailed questions, watch the attached video and I'll be waiting for your opinions in the comments section.
Enjoy!
