Hello daddy. With Arduino you can make all kinds of gadgets. It's basically just a piece in the puzzle of the project your son is making. Without knowing more about his project there's nothing we could say that would help.

>So, I'm here to ask if anyone can give me code to help him get started.
Buy him a book , a good book and let him learn his own way.
Just give him good sources of information don't spoonfeed him.

What this fag said. Also including his age would've been helpful, is he a toddler or a manchild like most of us here?
Good luck bonding with your wife's son :^)

I worked with Automation in high-school in my country, and I think we had somethimg named NPN sensors. They give out voltage depending on promixity of objects/ things (such as a regular human hand or a chair)

You could connect a motor that spins some wheels for movement of the robot. Connect the sensor to one of the GPIO's.

Something like this would have needed to be coded:

pinWheel = 8 (pin that goes to the wheel)
pinSensor = 8 (pin that goes to the sensor)
while(true) //True is always true, meaning an infinite loop
{
if (pinSensor == HIGH)
pinWheel = HIGH; // == compares values, = sets values)
else
pinWheel = LOW
}

On my phone atm, stressful to write shit. If youre interested I can post some of my projects to give you a general idea.

You really don't know the purpose of greentext, do you?

Also buy a beginner's book on Arduino and leave him to it. I'm getting started on Arduino soon.

Just buy the "arduino cookbook", it's not expensive and has plenty of good stuff for your wife's son.
