Another Pro Mini breakout board.

When Bajdi wrote his blog, http://letsmakerobots.com/node/40026 , about his undershield for the Arduino Pro Mini clones I was very interested and excited. This was because over the last few months I have purchased a few (20) of these Pro Mini clones myself. I was elated to see that there might be an easy interface board for my future projects.

Arduino pro mini undershield

The cheapest Arduino clone on Ebay is probably the small Arduino pro mini clone. I've bought some pro minis on Ebay for less then 3$ a piece from a Chinese seller. It's a tiny board with an ATmega328 running @ 5V. It does not have an USB/serial chip, so you need your own USB to serial converter.

Suggestion arduino Motor Shield with Brakes

 

Hi,

I have built my first robot (ultrasonic sensor, 2 wheels, 2 dc motors) using  he following motor shield(bought from ebay)

New V3 Arduino Driver Motor Controller Shield L298N 2A 2 Motors Module

Unfortunately my robot always bumps into walls. It turned out that I am not able to apply BRAKE.

Solves Just About Any Maze (When Completed)
Update: My robot placed 4th in the touch sensor maze at the National Robotics Challenge, and was nominated for the Honda Inovation award as well! The next step for … Read more

A custom Pi shield or an Arduino?

As more and more people get a Pi they are asking how to interface it to their robot. I do not own a Pi but I looked at the GPIO pins available for interfacing. Apart from general digital I/O pins you have I2C, SPI and Serial interfacing available. I assume there is a library or something that allows these pins to be easily access from within the Linux operating system.

So the question becomes do you just use another MCU such as an Arduino to provide the necessary I/O functionality or do you use a custom shield?

cheap wireless shields for arduino

I was looking for wireless shields for my arduino and stumbled across      this http://www.kickstarter.com/projects/1608192864/open-source-wireless-inventors-shield-for-arduino 

its a wireless shield for arduino that has 177meters range and is easy to program check out the link above for more info

Can Arduino shields be used on Picaxe

Hi,

I'm new to robotics, and just bought my first "LMR start here" robot kit. I haven"t recived it yet, but I am all ready having great plans about how to modify it (as I guess all newbies do).

So I have searched around to see what is out there, and I see that there are a lot of modules (or shields as they seems to be called in the robotics world) that can be conected stright to the Arduino.

So my question is, having just bought a Picaxe-28 Project Board, with a Picaxe-28X1 Microprocessor; can the Arduino shield be used with the Picaxe-28 Project Board?

ATTiny programmer shield

I got some ATTiny and now need to transfer the program from the Arduino IDE to the ATTiny without a programmer.

The solution is, just make your own programmer shield. Based on this tutorial http://hlt.media.mit.edu/?p=1229 I created my programmer shield for the Arduino Duemilanove. It's not pretty since it's just a ugly board out of my box but it works. Preparing the Arduino duemilanove according to this tutorial and then hook up the ATTiny into the header pin socket, open your sketch and click upload. Done!!!

Allows you to save data to off chip memory location as well as record rtc data.
This is a early LP shield that was actualy meant to have other features, but due to time constraints and wanting to get something to test with, I had to cut out a … Read more

Ro-Bot-X Board Reviews

 

Introduction

Recently, Ro-Bot-X send me three boards to evaluate. I had previously ordered his Robot Builder's Shield V1, and commented with some constructive feedback and a review on it after using the board for Penny.

LaunchPad Breadboard Shield link

I found some interesting MSP430 projects on the simpleavr.com website, including this LaunchPad Shield. It is just a breadboard for prototyping, but I thought it was pretty neatly done. I may create a variation.

There are a couple of other projects posted as well, with the promise of more to come.

Also, this person works exclusively in Linux, so if you are a Linux user looking for help on the MSP430, you may want to check out this site.

My 1st non-breadboard circuit :)

I know..a lot of you good folks could solder before you could walk and probably sleep with a soldering iron under your pillow (hope you remember to turn it off :), so here is this guy in his 30s bragging about his first circuit. Pathetic.

However soldering is a major challenge to me and actually the main reason I didn't get started with robotics years ago. It's just not easy for my unsteady hands. So I'm very happy to declare that I just finished my 1st working non-breadboard circuit. It's a motor+servo shield for my Arduino.

Arduino Shield Layout

I am planning to use a simple Arduino Shield for my next project.  I would like to use DipTrace to do this.  Before I start trying to measure distances between pins on the Duemilanove board, I thought I'd see if anyone here has a DipTrace file that could be used as a starting point for a shield.  If so, I'd appreciate a copy.

Suggestions on choosing motor

Hi

Im considering on buying the following motor for my project.

Quick specs : 12V, 150 RPM, 195 oz-in torque, 67:1 ratio

UGV Monster truck platform

I'm planning to build a UGV monster truck, based on a Tamiya Super Clodbuster. I've heard that it's a lot cheaper if you buy it in pieces. However, I ran into a bit of a dilemma. The stock monster truck comes with a speed controller. Do I need that too (I don't need any RC functions) or can a motor controller for Arduino or Basic Stamp do the job too. I already own a BS2 with BoE, but I would like to buy an Arduino because it's cheaper, open-source etc. Note: I'm still a beginner in robotics.
