No, I absolutely did not.
If you're thinking of making any progress in programming, you need to develop a sense of attention to detail.

I'm just blindly copying and pasting code and trying it hoping to get code that works.
You might as well just try to read your code from chicken entrails. That approach leads to hair loss.

Post a schematic. I don't see how the batteries are connected in series there.
The 7805 will be smoking hot having to reduce 24V to 5V.
Unless the batteries are isolated from each other, I don't see how voltage will not rise above Vcc after the first battery.

What about maybe using an Easyvr voice recognition module?
How does that help?
The OP does not want to recognise a word he wants a robot to move it's jaw as a word is said.

Sans changer de servo, une petite démultiplication par came doit faire l'affaire (un demi disque juste un peu renflé, qui augmente d'un millimètre sur 180°) en utilisant le demi tour complet du servo.

Correct me if I am wrong but from what I got from the diagram is

THE VERTICAL ROWS (26,25,24,23,10,9,8,7) are where I would use the common anode on the led correct? and then the horizontal rows are connected downwards to each led, red with red blue with blue then green to green?

Is that correct?

Thank you I will try the code you have posted tomorrow. I am in bed now. Please just look at it from my point of view. I don't understand pointers and casting. And you told me I must just forget programming as a hobby. I'm pretty discouraged at the moment. I have bought wireless modules to get my laptimer working without wires. Ok so what am I trying to do? I'm just blindly copying and pasting code and trying it hoping to get code that works. When I get code that works I plan to sit down a whole day and go through it trying to understand what it is doing. So u can't say I am not trying. I spent my whole day today trying to get this to work. Anyways

About pointers now again.  Does anyone have a link to a graphical representation of pointers and casting? Maybe for stupid people like myself? Words don't work for me but maybe pictures will

It depends on the size of the current. The simplest way is to measure the voltage drop across a series resistor and then use ohms law to calculate the current.

The main disadvantage of this is that the resistor will drop a voltage and so reduce the voltage to what ever you are feeding it to.
Also unless the voltage is less than the supply voltage of the arduino you have to put it in the ground leg of the circuit which can give you ground troubles.

In the buttonState function I tried putting the read instead of write block and it just outputs the first number I entered.
You haven't posted a button state function, however, if you're reading back the value you wrote last, then that's a good sign, and if it is the same as the value you're about to write, then you don't need to bother - it's already there, which also means you don't have to worry so much about the switch transition problem I mentioned.
