@jsotola: that's true. I don't think this is widely used in Arduino projects. Anyway, I added that to the answer

@Chris: 5V/440mOhm=11A. The Arduino can handle a maximum of 500 mA on its 5V pin. Also, you need a 28W resistor to handle the power, otherwise it'll go up in flames. It's ok, if you have considered all the electrical stuff. I just don't consider that the "normal" Arduino usage.

@Chris: I've updated the answer according to the schematics

"should allow": does it, or doesn't it?

@X0r0N: be aware: the SG90 can hold ~1 kg in 1 cm distance, 100 g in 10 cm distance and 10 g in 1 m distance. You'll need a much more powerful servo.

If 20 cm is not long enough, what is long enough then? 2 m, 200 m, 20 km?

@DuncanC: you're probably right. That should be a 2D table.

"The Arduino Serial Monitor window limits you to 115200," - That's no longer true. It goes up to 2Mbps

Where did you draw this circuit online?
