Arduino nano setup

I was wondering if I could hook up an arduino nano to a micro breadboard. 3 servos and a Ping sensor would be connected via jumper wires to the breadboard. Can this be done? How though? Thanks!

How to use Arduino interrupt in GR Sakura?

Hi,

I successfully ran a code snippet on Arduino . The arduino code uses timer 1 for interrupt and looks like this...

Is an Arduino Capable of Reading All Four Rover 5 Quadrature Encoders?

Note: Sorry this post is so long. I used bold text to indicate the main point of the post.

I didn't want to hijack Oddbot's Rover 5 threadso I'm starting this one here in the forum.

In replying to odong's question about the quadrature encoders I stated (among other things):

Wild Thumper Controller Compilling Issue

Hello:

I recently purchased a Wild Thumper Controller for my Wild Thumper . I tried to modify the controller software to use a LiPO battery and to test my ability to compile the code. Unfortunately I ran into several problems. The Fist was:

I was using the 1.0.5 Arduino Compiler:

         The Compilers are not backwards compatible and you must use the 0.0.18 IDE. (Thanks Russell Cameron)

Turning too much

So the robot I built is a two-wheeler, well three-wheeler, its got one small rotating wheel on the back. It uses an ultrasonic sensor to measure distance. My problem is that I'm having hard time making him go straight. Neither of the two DC motor driven wheels is more powerful than the other, they rotate at the same speed, and I programed them to do so.

Arduino Sketches are "Evolving" for Official Robot.

When programming my "Official Arduino Robot" I have noticed that routines that would work on my previous robots need modification (this is under Arduino Sketch ver 1.05.)

Example:

PROJECT CONTINUED! So I found a motor from a toy. Works fine. The same speed as the other. But I still have the problem with the whole robot turning. I'll post a … Read more

Service Droid

Working for DAGU means I need to try and design products that are not just cool to look at or play with but are also affordable and easy to use for the beginer. Sadly this balance is not easy to acheive. Usually more fun / cool functions means more complexity and cost.

Reverse pendulam using Rpi,Arduino and additional 0.75kg - which rover 5 chassis to buy

Hi

 

i am trying to built a autonomous car ( which can also be controlled by wifi) using DAGU rover-5 chasis , dagu 4 channel motor driver , raspberry pi (for wifi and camera) and arduino uno. i also like to use the same platform for inverted pendulam project using MPU6050 which is my next stage target , so the car needs to be very swift or agile to maintain the balance and change the direction.

Code Post - Interfacing Arduino and Python

This is something I've done by hand at least ten times and always seem to lose it so I've decided to post it here. It is an easy way to debug and test stuff will developing software for the Arduino (or any Microcontroller really). There is a python code that sends string messages to the arduino over serial based on which arrow key on your keyboard is pressed. There is also an Arduino code that listens for these messages, then repeats the message back to the PC to make sure it went through.
