So, while I was messing around with my electronic circuits and ran across this AI Tool generator website called Calculator Academy. The coolest thing is I tried it and it generated an awesome regulator voltage divider page in about a minute. Here is what I asked the AI to generate.

Regulator voltage divider with Vout, Vref, R1 and R2. Calculate for output voltage, Regulator Reference Voltage, R1, R2 where all but 1 variable is known. R1 is to ground and R2 is to Vout . Vref is between R1 and R2. Label fields specific to use.

```html
<html>
<head>
<title>Voltage Divider Calculator</title>
<script>
function calculate() {
    var Vout = parseFloat(document.getElementById("Vout").value);
    var Vref = parseFloat(document.getElementById("Vref").value);
    var R1 = parseFloat(document.getElementById("R1").value);
    var R2 = parseFloat(document.getElementById("R2").value);
    
    if (!isNaN(Vout) && !isNaN(Vref) && !isNaN(R1)) {
        R2 = R1 * (Vout - Vref) / Vref;
        document.getElementById("R2").value = R2.toFixed(2);
    } else if (!isNaN(Vout) && !isNaN(Vref) && !isNaN(R2)) {
        R1 = R2 * Vref / (Vout - Vref);
        document.getElementById("R1").value = R1.toFixed(2);
    } else if (!isNaN(Vout) && !isNaN(R1) && !isNaN(R2)) {
        Vref = Vout * R2 / (R1 + R2);
        document.getElementById("Vref").value = Vref.toFixed(2);
    } else if (!isNaN(Vref) && !isNaN(R1) && !isNaN(R2)) {
        Vout = Vref * (R1 + R2) / R2;
        document.getElementById("Vout").value = Vout.toFixed(2);
    } else {
        alert("Please fill in exactly three fields.");
    }
}

function reset() {
    document.getElementById("Vout").value = "";
    document.getElementById("Vref").value = "";
    document.getElementById("R1").value = "";
    document.getElementById("R2").value = "";
}
</script>

So for the most part it is correct. Wow, this is very awesome for about a half hour of messing it really paid off I am going to have to remember this site for future endeavors! Below is the corrected code the issue with both Vout and VRef calculation was it had R2 where it should have had R1 so I modified the code and it works correctly.

<html>
<head>
<title>Voltage Divider Calculator</title>
<script>
function calculate() {
    var Vout = parseFloat(document.getElementById("Vout").value);
    var Vref = parseFloat(document.getElementById("Vref").value);
    var R1 = parseFloat(document.getElementById("R1").value);
    var R2 = parseFloat(document.getElementById("R2").value);
    
    if (!isNaN(Vout) && !isNaN(Vref) && !isNaN(R1)) {
        R2 = R1 * (Vout - Vref) / Vref;
        document.getElementById("R2").value = R2.toFixed(2);
    } else if (!isNaN(Vout) && !isNaN(Vref) && !isNaN(R2)) {
        R1 = R2 * Vref / (Vout - Vref);
        document.getElementById("R1").value = R1.toFixed(2);
    } else if (!isNaN(Vout) && !isNaN(R1) && !isNaN(R2)) {
        Vref = Vout * R1 / (R1 + R2);
        document.getElementById("Vref").value = Vref.toFixed(2);
    } else if (!isNaN(Vref) && !isNaN(R1) && !isNaN(R2)) {
        Vout = Vref * (R1 + R2) / R1;
        document.getElementById("Vout").value = Vout.toFixed(2);
    } else {
        alert("Please fill in exactly three fields.");
    }
}

function reset() {
    document.getElementById("Vout").value = "";
    document.getElementById("Vref").value = "";
    document.getElementById("R1").value = "";
    document.getElementById("R2").value = "";
}
</script>

Corrected Code Above Note R2 needed to be replaced by R1 bold above.

One Last Note

Here is the version of AI prompt that generated the corrected code also shown below.

Vref is between R1 and R2. Label fields specific to use. Vref = Vout * R1 / (R1 + R2); and Vout = Vref * (R1 + R2) / R1;

Ok Last one I Promise

I used Grok to test this out too.

html code to calculate Regulator voltage divider with Vout, Vref, R1 and R2. Calculate for output voltage, Regulator Reference Voltage, R1, R2 where all but 1 variable is known. R1 is to ground and R2 is to Vout . Vref is between R1 and R2. Label fields specific to use.

Here is Grok’s result

Also, I had to remove the styles from the Grok code as it was messing with the entire post. Other than that, the Grok version works flawlessly. Wow, thanks Grok! I will be looking to it more in the future for my calculations and may bring more calculators online because it is a big part of what I do these days.
