R/C truck driven by an iPhone
Inspired by NerdKits, the iPhone connects to car.php
, a web page running on a laptop with WAMP installed. car.php
send x/y drag coordinates to newVector.php
, which transforms the coordinates into characters to send to the PIC. Then, echo.c
on the PIC reads the characters and turns them into drive commands for the car.
Grading: 50 points
- Scope -- very broad; covers a web server, iPhone, PIC, and an R/C trunk.
- Functionality -- good. The response time is a bit slow, but expected given the multiple domains (iPhone / web / PHP / serial / PIC / RC).
- Hardware complexity -- reasonable -- open-drain digital I/O.
- Software complexity -- excellent -- work in PHP and in C.
- Presentation - well done and explained.
- Practicality / usefulness / fun factor - excellent.
