Can the arduino (one of the small ones) be used to check resistance then push a variable wattage amount set by a couple of buttons?
I'd like to make a custom vape a the next couple of months.
Hi,
What do you want to measure the resistance of?
What do you want to do when you have?
a variable wattage amount
I assume means you want to control an output voltage, but for what?
What is a vape?

A re-buildable coil on a 510 connection.
Once I have the resistance I want to push a constant wattage (that I can change up/down) to the coil from the battery.
A vape is an electronic cigarette used to help quit smoking/enjoyment.
I'll also like to measure the battery and other things for safety.
Low voltage protection
Low resistance protection
High input voltage warning
Output short circuit protection
Reverse battery protection
Probably with an 18650 high amp drain battery.

Why would anyone want to quit enjoyment?

Why would anyone want to quit enjoyment?
If(battery_charge > 600){
if(coil_resistance > 500){
digitalWrite(quit_smoking,HIGH);
}
else{
digitalWrite(enjoyment,HIGH);
}
}
}

Ok I laughed.
Hi.
Okay, what is a 510 connection.
What is your electronics, programming, arduino, hardware experience?
Do you want to control the voltage to the resistance so it dissipates a constant wattage?
Wattage is not directly controllable.

One of the easier ways is probably using nichrome-wire (it can take a lot of heat) and calculating its resistance based on length and gauge. That will give you the possibility to calculate the nr of watts at a certain voltage.
Once you've chosen a maximum wattage, you can pwm/analogwrite() a mosfet (an arduino can't handle the power) to choose a lower setting.
