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?

Intel Edison Base Shield compatibility

Hi everyone, I was selected for the IoT invitational of Intel + Instructables and I as I was going to start testing the sensors I received, I noticed that there was no base shield for the sensor connections included in the package. I suppose the rest of the chosen participants didn't receive the base shield as well.

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... Thank you

Problems with my arduino mini shield

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

Arduino motor shield, do the shields not use the same stepper motor sketches or commands? Answered

Ok, I have an arduino uno and arduino motorshield. My stepper is a 1.8 degree 75 ohm motor, i can get it to run in one direction, or the other, but what I'm having trouble with is the code really, all the examples Ive been messing with don't seem compatible with the shield, all i want to do is make the stepper go one direction for "x" amount of steps then reverse the same number back, at a set rpm/speed, however when i try to give it step commands it does nothing, seems like i have to use the digital pins to control speed. but that's not exactly working for me. I'm sure this is an easy code for anyone who has used an arduino , but Ive only had this for 4 days and spent the last 2 researching and learning code, I'm getting frustrated. I thought getting the motor shield would make this easier...but it seems to over complicate, maybe not .maybe Ive just over analyzed this. if anyone has a code or recommendation for the arduino motor shield it would be greatly appreciated. here is an example of something similar to what im trying to do, but im trying to get it to work on an arduino motor shield.(example from Tom Igoe) /* Stepper Motor Controller language: Wiring/Arduino This program drives a unipolar or bipolar stepper motor. The motor is attached to digital pins 8 and 9 of the Arduino.  //motor shield pins 8,9 are the motor brake, use other pins or is this //correct? The motor moves 100 steps in one direction, then 100 in the other. Created 11 Mar. 2007 Modified 7 Apr. 2007 by Tom Igoe */ // define the pins that the motor is attached to. You can use // any digital I/O pins. #include #define motorSteps 200     // change this depending on the number of steps                            // per revolution of your motor #define motorPin1 8 #define motorPin2 9 #define ledPin 13 // initialize of the Stepper library: Stepper myStepper(motorSteps, motorPin1,motorPin2); void setup() {   // set the motor speed at 60 RPMS:   myStepper.setSpeed(60);   // Initialize the Serial port:   Serial.begin(9600);   // set up the LED pin:   pinMode(ledPin, OUTPUT);   // blink the LED:   blink(3); } void loop() {   // Step forward 100 steps:   Serial.println("Forward");   myStepper.step(100);   delay(500);   // Step backward 100 steps:   Serial.println("Backward");   myStepper.step(-100);   delay(500); } // Blink the reset LED: void blink(int howManyTimes) {   int i;   for (i=0; i< howManyTimes; i++) {     digitalWrite(ledPin, HIGH);     delay(200);     digitalWrite(ledPin, LOW);     delay(200);   } }

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 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.
