There is a sketch to display GPS informations from TinyGPS librarie for Arduino, the LCD is a 4×20 characters, wired through a I2C connection.
Before, you need to download and install:
– TinyGPS++
– Arduino Liquid Crystal I2C (mine use 0x27 I2C adress, in case you don’t know, use a i2c scanner)
(picture on top show the test with a Arduino Pro Mini, LCD 4×20 and EM-406 GPS head, the Lat/Long display is fake for the pictures only)

I have just retrieved a small gps buy from ebay, called Mini GPS (enf pg03), cost around 20€ …
It is a small size and portable GPS receiver with data collecting and calculating functions. It also provides indication of geograpic coordinates, directions, world time, distance, milage, and velocity information. Its high-sensitive direction indication guide user to go back original departure position or go to the presetted target position. The unit shows clear travelling date in detail, such as, the direction of the target position, distance, satellite time, and velocity information in usage.
This small unit do not provide to record tracking informations … so, start to disassemble it, in the goal to record NMEA sentence. Continuer la lecture de PG03 MiniGPS and tracking recorder
Like many people, i buy, time to time, some chips or shield from Chinese (dx, aliexpress, ebay) vendors, unfortunately my FTDI FT232 breakout was a fake chip, here he is a interesting thread about that.
Jordi Binefa , (thank, you made my day), describe a quickly and easy method to recover a bricked chip, you need have Linux, you can use a live cd/usb instead installed version if you prefer. Continuer la lecture de Unbrick FT232 counterfeit chip
– The goal
This will help to see the state of roads, in live, just need to load your favorite (urban or not) traffic map.

Update [17/02] – Project redesigned, look this following post.
Update 27/01, I ‘ll finally use ESP8266 chip, for the same cost, Wifi connections on the probes will be more flexible, eliminate any constraints, quantity of probes, signal multiplexing, and data exploitation …
Under development, some wireless probe in the goal to send data’s, temperature and humidity level directly to arduino, with displaying on a 2×8 LCD in live, using NRF24L01+ RF chip and DS18B20, DHT22 probe. The board is compatible with both. Continuer la lecture de Wireless RF probe for Arduihome
