I hope to please share a little robot that I have just finished building.
There are many Ping Boat, perhaps with a tutorials and display less so without pretension, will illustrate what I could do.
I gave myself the goal of realizing a robot that avoids obstacles, hence the use of Ping, who had more autonomy (and less hassle to reload always stylus) and displayed on a LCD display the distance measured obstacle.
The tutorial is directed for beginners but with knowledge of electronics and Arduino programming.
Step 1: List of Materials
