Nice Arduino-Motor PCB made by Guilherme Martins and his friend David Palma
Still looking for a Buy button somewhere in the site. Maybve we’ll have to wait for the next black batch to be produced for that
main features of the board:
– easy to use, understand, play with;
– must be a plug-and-roll board;
– to be suitable with shields, and with regular Arduino Diecimilla/Duemillanove boards;
– the usage of the H-Bridge is open, i.e., there aren’t any Arduino output pins assigned, the user can use the bridge the way he/she wants;
– motors supply and PWM pins might be used with external voltage or regulated 5 volts
– motors have 3 different connectos, screws terminals, male headers, JST connectors
– two possible FTDI/USB connections available
wow. Android G1 Driven Bot!
Playing with apps on an Android phone is fun. Building your own apps, even more so. But what about using the phone to operate a moving, talking bot? Tim Heath and Ryan Hickman have done exactly that. [...]
They could have purchased the pricey $175 Oomlout kit, which includes wheels, motors and an Arduino-based brain. Hickman and Heath opted for making their own chassis. Here’s a full list of parts they used:
- $16 Bare bones Arduino
- $3 Micro servo
- $0.25 Hex inverter (handled 3.3v to 5v conversion)
- $4 HTC USB breakout board
- $4 miscellaneous cardboard, strap ties, wires, rear wheel
- $3 Mini breadboard
Wow. I definetly have to check this step by step guide to build your own Processing-controlled car.
Toy Hacking is one of the best way to learn how to deal with little hardware. Very well detailed.
All logic controlling the vehicle is performed in a Processing program running on remote computer. The Arduino program listens for commands from the remote computer. Bi-directional wireless communication over XBee radios with (theoretical) 1-mile range. I’ve accomplished 1/4 mile range with these radios. Sensor events are transmitted from the vehicle to the controlling computer. This vehicle has 3 microswitches – two on front bumper and one at the rear. Original circuitry of vehicle replaced with dual H-Bridge circuit to control drive motor and turn motor. Drive motor is controlled with variable speed. Power: Vehicle motors powered by 4 AA batteries. Arduino with XBee shield powered by 9V battery mounted at front of vehicle. Simple communications protocol: 2 byte commands from controller to vehicle, one byte sensor readings from vehicle to controller.
