Tell us about yourself!
Is it safe to cook over this hot metals?I mean that when people (in my country) make grills from kegs (oil unused) they make a fire for hours before painting them (the ouside) so it wont have harmful materials (I think).I have an ammo can like yours (that had lots of thing after the ammo) and think that a preliminary cleaning by burning should be necessary before cooking in it. Or I'm wrong. Thanks!
A few months ago I took a mini course about nanomaterials (Laboral health safety) because I'm aware that these nanomaterials are already here and will stay (many people doesn't realise that chemistry is everywhere!). So when I read "quantum dots at the kitchen" I was very happy to find your instructable. So I'll try to show and explain my kids! I want them to be MAKERS not just users! :-)Keep doing!

How to Smooth PLA 3D Prints
Look that there are 4 motor wires, 2 by each motor. When turning in one direction you put HIGH and LOW (ex: pin1: HIGH, pin2: LOW) and the other direction the reverse (ex: pin1: LOW, pin2: HIGH). Never HIGH,HIGH.Notice that LOW/LOW: Is a stoped motor.
Yes, you only have to look for pin equivalence. Remember that the number of the pins are not the same as the name of the ports. Ex: pin number 27 can be D10 (writing by memory). And you put in your code the pin number, not the port.
You can either use Digital output (High/Low) from arduino to go ON/Off to control the moto, and you can go further and apply PWM (need a PWM out + Digital out) to control speed. Digital turns on the motor in the direction you want and PWM tells at what speed.
