Notation(s)

1. More or less, this was to reacquaint my self with the MKR1000(s) I had been given at MakerFaire (Thx Arduino's Arturo and Christina!) using scraps being thrown out while in the process of moving [again] -- before the great war.

2. Learning to prefer to self host IoT streams -- if better positioned, I would implore and collaborate with some one to create open-source privately hosted IoT software for your own domain - so as to permit more flexibility of function. Hint hint, nudge nudge, Hackaday!

3. As said, only scraps -- no digital potentiometer or transistor? Hold my Don Julio -- wanting to thread 120V, we [me] improvised with a servo and hot glue. https://hackaday.io/project/27578/log/68403-no-digital-pot-or-transistor-hold-my-don-julio #Hackcycling

4. Shelved bcz - meh.

5. The motion sensor and a-to-be-abandoned-Arduino-Uno were then applied to an entrance way motion triggered random Neopixel display [included in the video and code included below]

    Dumping the bubbler version bcz of disinterest and time - building an Arduino motion sensor Neopixel display for the current occupant -- of an over valued Queens, New York apartment that I would not even wish on the plague.

  • No Digital Pot or Transistor? Hold My Don Julio!

    Every one knows how to turn a servo with potentiometer -- how about a servo to turn a potentiometer?! Needed to map control of 120 volts using what was in my box of bits 'n pieces.

There's already a pot in a servo !

  Are you sure? yes | no

Vije Miller wrote 2 days ago point

The pot the servo is controlling is regulating the pump's voltage (120V) -- another words - the Arduino is controlling the servo pot which is turning the head which is turning the pot which is controlling the resistance to the pump.

I understood the limited resources as I read the title. But EEpots and generic transistors don't sustain mains voltage anyway. I don't know your available parts - not everybody has servos and arduino at home 😀 - or your experience in electronics. So my comment was only a suggestion. I did not expect that this small pot survived in a power application.

What?! Not every one has 2 Unos 2 MKR1000s 1 NodeMCU and 6 servos laying around?! Of course, for me right now it was that and 6 pieces of Neopixel, a couple of miscellaneous resistors and just 1 screw driver - so technically - all brains no brawn. As to electronics experience, I am far more mechanical engineer than electrical. As to it working - the pump is only a solenoid-magnet that charged and discharged to push another magnet back and forth so - resistance would primarily slow the charge. It worked and the pot did not raise in temperature - uh hem, that is why us mechanical engineers get shit done, screw the rules! 😀 - the project how ever sucked and I got bored and dumped it. I did take to your advice and did appreciate the input - tho having to google a few terms. I know things like "wood" not "zero crossing detection"

Do you really control the pump directly with a series resistor? How much power/current does it use? I would do this with phase angle control. Optocoupler for mains zero crossing detection to the microcontroller and MOC3020 or something (without internal zero switching). If your current is well below 100mA you do not need an extra power TRIAC.

  Are you sure? yes | no

It is vaguely implied above that this was bcz I did not nor have easy access to or have time to obtain or want to presently obtain any other components while/before moving -- thus this was a hack based on what I had. McGuyver'd.

  Are you sure? yes | no
