Modulation, there is just one thing you can measure on and adeno pin, and that is a different in voltage. So keep in mind, the only signal sensor is sending to an adeno is a voltage value in the previous video. We talked about the digital pins and in this video we’re gon na take a look to the analog side and on and adeno you know, we have 6 analog pins from a zero to a 5 and we can read a value between 0 and 1000 23 and That’S a 10 bit value and we can write to the pin of value between 0 and 255 and that’s one byte or 8 bits, and if you are not familiar with bytes and bits, please watch part 5 from this playlist and analog pin can handle our voltage Between 0 and 5 volts, so, if we read through the pin, we can say that we have 1024 options and if we divide them by 5 volt, then we can say that 1 volt is equal to 204 change. Our output – and this is called an analog to digital converter. We convert an analog value to a digital number in general. Sensors have a sensitive voltage component, and this component react on our difference in the surrounding environment. If there is a change in the environment, the component will increase or decrease the resistance, for example, this light sensor. The component has a fairly high resistance value, as you can see in serial monitor, it’s a it’s around 18, but when I put a light on it, the resistance will drop and the Fulton’s will increase till 7 between 55 to find out the specifications of your sensor.
You have to read the data sheets and the other seats are written by the makers and they are full with the information about the center they’re not easy to read. But if you want to know the boundaries of the sensor, you can find them inside the data sheets. If you have a solid incoming sense of value – and you know the specification of the sensor, then you can map it inside the software and a few months ago. I made a youtube video about this, how you can translate incoming sensor value to a temperature in Celsius, and I will put a link to this video here or if you look from a mobile device, you can find it in the description. Let’S, take a look to analog right, you would say I have 256 options and if I divide them with 5 volts, I can say that one fold is is 51 sensor inputs and if I analog write 51 to LED, then the LED will light up with one Volt but analog light is not working like this analog light is walking with pulse width modulation. So what is pulse width modulation? As you remember from the digital pins, they could be zero volt low, what they could be 5 volts I, but if we analog, write a value to up in. In this case we have a 50 high and 50 low in one cycle. If we divide 256 by 2, then VF 1, the 27, so this is called a duty cycle of 50, so pulse width.
Modulation is a digital technique to simulate our lower voltage. If an LED is on for half its to teatime, it wouldn’t fade as bright as it is for 100 and to make it more complicated. Almost all our Dinobots do support pulse width, modulation on a few digital pins and, as you can see here, it says pwn and our wife, and if you see the wave by the pins, then you know that those pins have pulse width. Modulation support you have to look it up, because all the different Dinobots have different pull width modulation pins. So if you work with pulse width modulation, you call the function, analog right and then the pin number, so you can do analog operation on a digital pin. And then you have our pulse width, modulation, operation, I’m, here on the Kadena website, and I looked up the analog height function. They wanted you to be aware that some pins like been five and been six on the adeno. We know our asset to our higher clock. Speed so they they are on 980 hats, while the other pins are set to 490 at, and this means that if you use pin 5 and 6 to light up an LED with the pulse width modulation operation, then the LED will light much brighter than if you Do the same operation with this time you use pin 9 and 10, for example. If you need for some reason our Hill digital to analog converter, then you have to order the Dino a 200 baht, because that’s the only board so far as I know, were supports to analog output.
So we have digital right and we can set this pin high or low, and we can hide these two all the pins on the bot and we have an analog light and we can write our value between 0 and 255 to all the analog pins and to A few digital pins – and if we do this, then we start our pulse width, modulation, duty cycle: this is the end of video.
