Overheating stepper shield

Hi Everyone, As I'm a newbie, please forgive my ignorance for asking what maybe an obvious question.  I've got an Arduino Uno and a DK Electronics v1.0 motor shield (powered separately at 12v). I downloaded a library and managed to get a NEMA 23 stepper motor working. Trouble is, the chip on the shield doing all the work gets scarily hot in next to no time. The rated current of the motor is 1A, although when I tried it, it was under no load. I've checked the power consumption when driving the motor from a standalone controller and it's drawing no more than 250mA. Do you guys think:- a) I'm overloading the shield? b) I've got a fault? c) I scare too easily? Any feedback will be gratefully received. Thanks

K'NEX Riot Shield

I've had this idea for a while, and I am kinda assuming that it is a pretty bad one, but do any of you think that a K'NEX riot shield would be of any use? At least, in an out door K'NEX war? If it could withstand a 5 rubber banded oodammo from a TR8, would it even have a chance of being used? And, keep in mind, I'm not talking about making a cheaply done K'NEX shield like the ones we've all seen here on instructables, I'm talking about a good quality, sturdily built, K'NEX riot shield. What do you guys think?

I would like to make a board that has both a bare-bone arduino and a wave shield. Adafruit has the schematic for the wave shied, but I have a very limited understanding of what it is I'm looking at. I understand (or think so at least) that the MOSI would go to pin 11 on the arduino (using this).

Need help in identifying connections for CNC board?

I need help please anyone. I have bought another CNC shield recently, goes by the CNC Shield ver 2.7 name. The board has www.lubandiy.com printed on one corner. There are 8 optical isolators on the board for the limit switches and a socket for a Nano. Also there is a heavy duty hexfet near the laser connections. I am not able to find out much about this board, even though I have asked the seller and even a few other sellers that are on ebay. I went to the website as shown on the board, but it is all in Chinese and after trying to use Google translate was still not able to find out any further information. The board looks well made and seems to have a lot of good features, but lacks the needed info to be able to put it to good use. I am not sure if the board has a laser TTL built in or not, it is possible due to the hexfet being there,  There are two heavy duty connections (two pin each marked + - ) and a small connection with a xh2 socket that could be for a laser or maybe a fan.  Can't get any further info on it. If anyone can help with info, please let me know so I can start to use the board with my machine build. I have managed to program a Nano with GRBL 1.1f and it works OK when testing the board on a dry run, no motors connected or laser.

A Beginner’s guide to making an Arduino Shield PCB

So you’re pretty fond of your Arduino. You make blinking lights, and beeping noises. You’ve made a robot that was pretty cool. Or maybe you didn’t. Who cares, You’re ready for the next step. You want to extend it. Although you can just plug in wires, there’s something very appealing about making a shield. Instead of a rats-nest of wires piled about and plugged into your prototyping breadboard, you can have a nice clean shield with labeled connections and a smaller footprint. So here I’m going to tell you everything you need to know to make a schematic and PCB layout, and get a beautiful shield that will plug into the top of your Arduino For More Check Out this blog.

Using Adafruit Motor Shield in MATLAB

Hi All, I am quite new to robotics, facing an issue and looking for expert advice, appreciate if you can guide me. I got Aurdino Uno connected to the laptop, set up all good. connected a potentiometer to the board, and could read the voltage in MATLAB from 0 to 5 V, all ok. Connected a DC motor to Adafruit Motor Shield, connected 5 V DC power to the motor shield. connected the motor shield to the Aurduno board (put it on top of the board, but loose, no soldering involved).  MATLAB is not recognizing the shield and see error message like the hardware disconnected. This might be a silly question, I can use  stackable pins, solder to the motor shield and then connect it to the Aurduino board. In that case, every input/output pins of the Aurdino will be connected to the corresponding terminal in the Adafruit Motor Shield and also available from the top (by stackable pins) to connect potentiometer etc... Is that how i can get the Adafruit Motor Shield recognized by MATLAB? need to use a few potentiometer for my project, so need to have the analog pins available. Also, just wondering: which pins establish the communication between Aurduno and Adafruit Motor Shield? using stackabke pins will connect all of them, but i can not figure out how connecting the analog pins of Aurdino to the motor shield adds any value...

LED Car Badge/Emblem/Shield

Hi there, Firstly, I am a mechanical engineering student with a limited knowledge of circuits and electronics, so therefore I may be a little out of my depth. However I am very keen to learn about electronic circuits and have completed other simpler projects and that is why I am attempting this project. So onto my dilemma, I want to use my universities Shield of Arms to make a car badge for the single-seater racecar we are building as a project. However this badge won't just be a run-of-the-mill plastic car badge. I want it to be made from stainless steel (laser cut) and acrylic with the idea that I will solder a bunch of LEDs in series and when the ignition is turned on, the LEDs light up one at time until they are all lit, after which they all flash three times together and then remain lit up until the ignition is turned off. The LEDs I intend on using are 0603 SMD LEDs and the aim of this whole design is that it is reasonably thin (No more than 1/4 " or 6.35mm thick for the PCB however ideally I would like it to be as thin as is physically possible. The dimensions of the badge will be very similar to a Porsche badge (51mm by 69mm). I have included the Shield of Arms in question and also the Porsche emblem for comparison. Also price is an issue since as I am a student, I have limited resources, so if someone could point me to some cheap electronics parts shops etc it would be greatly appreciated. (I live in the United Kingdom so a lot of American shops will be unavailable to me) I don't really know how to read schematics but I do have friends working on this project who do,  however if anyone can guide me in the right direction with maybe a couple of how-to's (particularly the requirements for the lighting up process) and some really good pointers, it will be very much appreciated. If I have not made myself clear I do apologise and I will be happy to explain further should you need to. Thank you all in advance. I hope to hear from you soon. H
