Project #2 WiiMote + Arduino + RC Car = Hours of fun

Project 2: Arduino, Wii controller and RC car.

Project 2: Arduino, Wii controller and RC car.

I made a quick little project that allows you to control a RC car using the Wii Mote as input device. It works thanks to the WiiMoteLib, C# and the arduino. The arduino is used to interface a computer to the RC car controller, it could be replace with just a parallel port or something else. Please take a look at the fun little project, It has some potential to grow in to a much bigger project. Enjoy.

I wanted to summarize a collection of interesting projects posted during the last few months on hackaday. These hackaday posts included projects with RC Toys, iPhones, accelerometers, arduino, bluetooth and the Wii motes.

I decided to build an interface between the Wii mote and a remote controller car utilizing the arduino to interpret the commands from a Wii mote accelerometer.

Project #1 Ambient temperature sensor + “Wootoff” notifier.

I made a circuit that reads the output from a LM34 (temperature sensonr) and send the output to the computer using PIC12F683. I had some some spare pins on the PIC12F683 so I decided to use an extra pin to drive a BS170 Mosfet transistor. This transistor then powers the woot-off usb ligts. With a perl script I check if there is a wootoff and if so a signal is send to the PIC and the lights are turned on.

The project started with the curiosity to learn how to use the analog to digital converter inside the PIC12F683. At first it took power from the RS232 serial port connection on the server to power up the entire circuit. I also used bit banging to avoid the need of voltage level converter. This is the original schematic:
