How to blink an LED using Arduino and Simulink. There are many app and widget floating market for knowing outside temperature and humidity, but there are no app that can provide your Temperature and Humidity inside your home, by creating this app you can retrieve temperature and humidity data from arduino.Ģ.

if you don't have any prior experience with Arduino control, make sure you follow some basics like connecting Arduino to your computer and upload example code to Arduino from Arduino IDE, this would be more sufficient to follow this tutorial.

creating an app with MIT app inventor is very simple, you won't be doing any coding process during creating your app, you will be assembling blocks together to make your app. To test the app that created during this tutorial, you need an Android mobile or android supported devices to test your app. Blinking an LED is the first thing we do when we getting started with electronics in this tutorial you will TURN ON and TURN OFF the LED, this is the Hello world example in this tutorial, you don't need any prior coding experience to make this application work. A "motor rated" breaker will allow stall current briefly, but trip if the current persists for long.This video gives insight into MIT app inventor and what are the requirements need to get started with this video series, anyone watching this video can make their own app and control a LED connected to arduino without any prior experience, if they have components with that's more enough to make this tutorial. This is also the "stall current" which the motor will draw if you stall it while powered. To estimate it, measure the DC resistance of the motor - say 11 ohms - and divide 110 (or 230) by it (for 10A start current). It may be better to stop the motor, reverse it, then restart, to prevent extreme mechanical stresses and current surges.Īs for your other question : the 1 amp current is generally the current at rated load :you can bank on the starting current being much higher (easily 5x, maybe 10x as much). Then to switch between forward and reverse you need something like a DPDT switch (hand operated!) or relay (remote operated) to reverse these connections on demand. The rotor winding goes to the brushes.Īt which point a photo of the connection box is probably useful.īut assuming this is true so far, you can reverse the connections to one winding (usually the field winding which consumes less power) and test that the motor runs backwards - no circuitry needed so far.Īlternatively, the rotor winding may be accessible via screw terminals on the brushes. It's easy to identify the field winding : it has higher resistance and consumes much less power, maybe 10% of the total. If it is described as a reversible motor, these windings will be separately available as 4 external connections, possibly linked together, but in a way that you can disconnect one winding and connect it the other way round. To reverse it, you need to reverse the connections to the field winding OR the rotor, BUT NOT BOTH. The trick to reversing these and what sets them apart as more flexible than a permanent magnet motor, is that there are two windings : one on the rotor, and one fixed to the motor frame called the field winding.

So, simply reversing live and neutral will not reverse the motor. (As Olin says, the AC supply reverses polarity 100 or 120 times per second already. Assuming it's a "universal motor" which is the normal type of brushed motor running on AC, it will run equally well on AC or DC of either polarity, but always in the same direction.
