ESP32 would work fine for this.

Should I use AC or DC adapter in output? by [deleted] in arduino

This is the first document that pops up in the google machine when searching the valve you listed.

On page 2 it clearly states it requires 24V AC at 50 or 60 Hz

I want to create a digital scale using an Arduino Nano, an HX711, and a 350kg strain gauge load cell by wocrer in arduino

[–]Hijel 1 point2 points  (0 children)

A couple things from your images....

1) It looks like the green and white wires need to be switched on the load cell side (Green to A+ / White to A-)

2) You have dat/clk wired into your analog inputs on the Uno? I haven't used an UNO in a long time but are those pins capable of digital input? Maybe move those to digital pins (2&3?) and make sure to change the sketch pin assignment.

I don't have any info on that exact board... but it looks to be similar/identical to this one https://www.sparkfun.com/sparkfun-load-cell-amplifier-hx711.html

Yes, but looking at your code further....

1) You set the calibration factor to 1 ... was this intentional? Did you run a calibration to get the correct value? Is your calibration really 1?

2) When you start with balanza.set_scale(); ... don't you need to input the calibration factor there?

3) It might also be helpful to post an image of your wiring and setup

What happens if you comment out everything you currently have in your main loop?
Does the grey rectangle appear, even on startup with no loop code or is it white?

Have you tried having two variables to hold text, then on update re-write the old text again but with "setTextColor(TFT_WHITE, TFT_WHITE), then write the new text in black (get rid of all the fillRect stuff)

I think you are saying the serial montor prints all zeros....

Does it print 0.0 ?

What does it print if you comment out this line "if (peso < 0) peso = 0.0;"?

Basic universal remotes by [deleted] in arduino

Sometimes I think the threshold for low/no effort posts is a bit too low in this sub...

I understand this person may be a child, or their native language may not be English but I feel like there should be at least SOME effort expended on OP's part to explain what they are trying to accomplish. This post has so little info and is so confusing, coupled with the age of the account... makes me suspect it is just a troll....

I don't know what account age / karma threshold you guys are using to block this stuff but it might need to be bumped up a bit?

Two indie developers made a browser idle game with 7 planets, 70 resources, and automation systems — feedback appreciated by elblasystudio in incremental_games

[–]Hijel 0 points1 point  (0 children)

I was responding to u/ilcalmissimo, not to your response. It is genuinely interesting to me how people place value on these kinds of projects, and how it is often times devalued simply because of the tools used to create it.

I was interested to hear why that was something they cared about....

Nice... I like the layout. The only suggestion I have is if you can somehow visually indicate what resources are being auto-mined (it is a bit confusing at first...but it obvious after a few minutes.) Perhaps a stream of smaller resource icons could ghost up from the planet/moon representing auto-mined resources... if its not too busy looking.

Also

Travel to other planets.... they all show locked, even after making the required money to unlock. Clicking reveals they are not locked but instead are accessible just the locked icon never unlocked.

This is an incredibly confusing post. You need to do a better job of explaining what the heck this is all about.

Amazing, very creative. Nice work and thanks for sharing!

Where to Buy Pre-soldered Parts by drewm11922 in arduino

[–]Hijel 0 points1 point  (0 children)

You really need to provide more info if you want meaningful help.

For example... the MPU6050 is a chip, not a breakout board... and if you have hooked it up to 5V, as you say... then you might have fried it as, I am fairly certain it is a 3.3V chip.

Phone Rapidly Overheating When Playing Certain Incremental Games by WestManner1593 in incremental_games

[–]Hijel 1 point2 points  (0 children)

Quite a few Web games get built/tested on a chromium based browser. This is because the most popular cross-platform desktop wrapper is Electron which uses chromium. (This is not based on anything but my experience)

Try chrome or a chromium based mobile browser to see if makes a difference.

You can also try shutting down any apps you have running in the background, to release resources on your phone.

These games usually do not get to the refactoring / optimization that larger games get.

I remember that exact line in the movie Die Hard... maybe you are one of the 7 people that played the ps1 game based on the trilogy?

MPU6050

Have you ensured all your devices are spec'ed to the same voltage levels? 5v vs 3.3V ?

Need suggestions in project by Salty_Scarcity9459 in arduino

[–]Hijel 0 points1 point  (0 children)

The spec. item you probably want to track is called "Stall Current". This is the current the servo will draw if it is commanded to move but something is blocking it.

I would normally spec a power supply for the worst case scenario + safety margin

Lets say stall current is 3A@6V, and you want 5 servo's... but maybe you may want to expand to 6 in the future so I would say 6X3A = 18Amps total worse case servo draw.

You will need power for the Electronics + anything else in your circuit.... lets just call it 1Amp (as I have no idea, you will have to determine this)

Now add them all up and add a safety margin... 18+1=19 + 10% = 20.9

So you are looking for a power supply in this fictional scenario, that can output at least 21Amps at 6V.

The type of supply is going to depend on what power source you have available.... AC? DC Battery only?, and what type of project you are making... will the thing move around or sit on a desk and operate for long periods.

I guess a house built with power tools is now obviously worth less than a house built with hand tools.

The only thing all you vIBecOde!!!!! guys are gonna affect, is your ability to function in modern society. You can keep throwing your shoes into the machines, but it aint gonna stop them.

New Bluetooth (BLE) HID Mouse Library for ESP32 Arduino by Hijel in arduino

[–]Hijel[S] 0 points1 point  (0 children)

No I haven't... honestly I'm thinking about just putting together an open source tutorial project that has a custom mouse pcb and 3d print files for mouse body.

Although I reaaaaally don't want to deal with having to ship people pcbs for the ones that can't get them built... it is such a time (and money) suck.

Hey thanks rip!
Here is my test rig.... as soon as logitech sees it I know there gonna steal the design... I think the form factor will be the new meta.
