How To Connect & Use a Potentiometer With Arduino

Hello and welcome to the senior lesson in which we will talk about an analog to digital conversion and just this one I will explain how to connect a potential meter to an Arduino. The requirements are you you want a laptop Arduino microcontroller. You asked me to say adapter if your microcontroller does not have you as we want everybody to be cable show me to minutes and then these are the types of meta the circuit of this goes on should look like this.

Connect the meter Tobin's 0 5 volt and ground them indeed. Is there one took a nick to that bin and the voltage via's on the spin orientation of the other two bands. Does not matter. Now I will show you and explain to you every line of the code which is required to precede this lesson we will start by initializing variables as defined.

First and since I've been he was easy semicon then and since our man was chosen only to describe what value I wanted to present then to just sort of man is equal to zero where is zero is not zero on the Arduino on it's on. A zero is not a reserve term. However when used in context the system recognize it as an audible been zero. The line must end with a semicolon.

Like I said before by declaring a variable this tab you can use the term which in this case is some sort of pattern throughout the code. And instead of as you will there are two main benefits to this one. It makes the code more descriptive too. If you want to change the value of the variable you only need to do it in one place then. And since value equals zero semicolon the term since value is not reserved term either then lead equal  13 sénéchal. Once again the term Libin is not a reserved word in Arduino.

It was chosen to describe which bin was connected to then the value of 13 is a normal value. But just like a zero when used in context give reason spent 13 however you will need the following code and other void to been made an output which is used to declare that the lead has an output at last we read the void which will be repeated indefinitely since around you it was agreed since I've been cynical on this line use of the term and I love read in order to read the voltage of AM and I know been most microcontrollers used them. And I look to digital conversion in which voltage conversion which is due to the dense power of a number equals 1024 therefore voltage of zero corresponds to a nominal value of zero voltage of five corresponds to an added value of 1024.

Therefore I value everything evolved well correspond to an omni value which can be calculated like this. I wrote that equation. You can get the inside doing this three divided by five equals X divided by 1024. We were X on one side. So we tried three multiplied by 1024 all divided by five. That answer will be approximately six hundred and fourteen.

Then we died. Did you get it right. Which Dan's been on delay. The delay should take the delay time from sensor value which stops the program for how many seconds of this interval you then Digital's right. Did Ben know which devastated ben of the delay had been taken from sensor value. It starts with the program for milliseconds of the sensor value. As I said once the button meter is connected.

I bought this sketch to the board and it changed to the serial minuter as you read said the knob or slide the slider. The volume should change between 0 2 1023. Correspondingly valid will blink with a faster or shorter delay. You can now read the values and use them with your account then your function used here is and I disagreed.

Where have been selected has been number 0 if you use it. Then Number five you should change the code to read and since around 5 if the system does not track check the syntax and ensure that God Blonsky get the next check the connections to the potentiometer on shooting that then indeed goes to the correct bin and other been aborted at zero volt and 5 volt.

If you bought very cheap on all that and she meter has a chance it may be mechanically defective. You can test this using a multimeter and extends to that model been out. I've been sit multi-meter to read Jesus stands up. Resistance changes slowly but is working. That is just dumb is idiotic. You need and you couldn't Shamita. Now what if you want to see the value yourself. Take a look at the code that I display here and that is as a new sketch before initialize it a variable instance or append equals zero which select then but then for the button Shimit to then intenser value equals zero which is the variable to store the value coming from the sensor.

But some of your functions will be used now under the void. The void set up under the void tab we write See look began in between the brackets 9600 semicolon which initialize the CNN communication at Aldred or nine thousand six hundred. Then under the void log we write C and D to print and in between the brackets since her value then the semicolon.

This Since the value contained in the variable since value c via the US be blank and digital been run free by then and I'm not discouraged to Arduino. Once it's done based on going in fighting glass located towards the top right of the window this is silly I wanted to add monitors communications begin sending and receiving by the Arduino here. You must verify the Godhead is also nine thousand six hundred on. You will see garbage. Thanks for learning from this lesson. If you have any question please ask it in the queue and airborne.
