Good morning my dear friends. Today I'm going to give a short introduction to Air 293D Motor Controller. This is small typical Elton-E30 Motor Controller chip. With the help of this chip we can control DC motors to prevent the clockwise or anticlockfire direction. Usually if you want to run a motor then you provide positive on negative voltage across the input terminals of a motor and if you want to have multiple entities then you will reverse the input signals that is the input voltage you reverse it. But if you are doing it physically then it becomes very easy but when you're having a fixed connection then that's some lack of things. So the situation like that we're going to use an Elton-E30 Motor Controller. It says it's a small rough diagram that I've made myself. You can actually google it for a much better picture which I'm sure is on that of mine. Anyway so if you want to really control it then you're going to have to connect the Elton-E30 Motor across the output pins. You can see there are two output pins and two input pins. These two output pins of the chips are going to get connected to the input pins of the motor. Okay and we're going to provide the input signals to this Elton-E30 Motor Controller with the help of a microcontroller. This Elton-E30 Microcontroller understands only logic zero and logic one. So we're going to have to generate a logic zero and logic one that we're going to do with the help of a microcontroller. I'm going to show it in details in my next video tutorial that how I actually it's working. This one is just an introduction. There are two input voltage for this Elton-E30 Motor Controller. One is VSS and another one is VSS. VSS is for the VSS voltage just for the interval working out that chip. That means the chip is going to act or it's going to use for itself VSS. And VSS is the motor voltage. For example when the motor is connected across this Elton-E30 and you want to operate this motor at 16V at that kind of situation. We're going to provide a 16V across this VSS and VSS will be constantly at 5V. Now there are two parts of this Elton-E30 Motor Controller. This is the one part and this is another part. With this part you can control one motor and with this another part you can control another motor. If you're going to use this part then you're going to have to enable it. For that you're going to have to enable the chip enabled one. So if you're providing positive voltage across the chip enabled one then this part gets activated. For doing that I usually connect VSS with chip enabled one. You can see here also I'm activating with providing this chip enabled to this kind of similar thing. So I'm going to provide this VSS to this chip enabled one and this part gets activated. Then I'm going to connect more across these two terminals and this inputs will be connected to the microcontroller. And this is a common ground. All the VSS VSS enabled this will have a ground. Connect this ground together, this chip, this pin 4 and 5, pin 4 and 5 are also shot together. Now this chip understands only 0 and 1. So if you're providing logic 0 across this terminal and logic 1 across this terminal then a motor direction and a clockwise direction. And if you're providing logic 1 across this terminal and logic 0 across this terminal then motor it in a clockwise direction. That's how a simple basic L290 motor controller works. That's how you can actually do this. This L290 motor controller works on the principle of H bridge. You can do a short Google about what exactly the H bridge is. Now stay put to my next video. In my next video I'm going to provide a complete demonstration of this L290 motor controller with interface with my microcontroller. And I'll be controlling it with my computer. Thanks for watching. Stay put. Take care.
