Issue 1: Driving a motor directly from an Arduino
Driving a motor directly off the Arduino pins is not advisable for multiple reasons:
Load current, especially at motor start-up and stall conditions. As rightly pointed out in the question, the Arduino pins may simply not be rated to supply suf...
As far as I can recall, the Arduino doesn't clean up noise in the power supply. Some boards have smoothing capacitors, and other boards have nothing. This means that you'll have to put a smoothing capacitor in between your adapter and your Arduino to avoid accidentally resetting it.
I have a habit of writing code using all voids like below.
int led = 13;
void setup() {
pinMode(led, OUTPUT);
}
void loop() {
ledChange(HIGH);
delay(1000);
ledChange(LOW);
delay(1000);
}
void ledChange(int pinState) {
digitalWrite(led, pinState);
}
I re...

Arduino Stack Exchange is a site for users of Arduino or Arduino-like platforms and their development environments.
On topic questions generally are about:
A hardware or software issue specific to Arduino/Arduino derivatives
Specific Arduino shields
Specif...
There’s a bit of a leadership vacuum inside the new Stack Exchange communities in public beta. We’ve put a lot of responsibility on each group to take ownership of their own site. The Stack Exchange team can act as guide, but we don’t always have the domain knowledge to understand the needs of each group. As the Network expands, this stretches our ability to assure that each community’s issues are properly addressed.
That’s why I am in the process of identifying and organizing a team of provisional Moderators from within each community (about three per site, starti …
