why isn't the Wireless LAN communicating with the local network?》... what makes it a Raspberry Pi problem?

why drill through the siding? ... go through the back of the panel ... or follow the route of the other wires ... take off the breaker panel cover and see what goes where ... add a picture

why don't you determine experimentally how the display looks to you? ... it won't look the same to every person ... some will see a big difference, others won't see any difference, and others something in between
Sep 11, 2024 19:52
@GeorgeNtoulos post answers as answers not comments ... your question is off topic here... an answer would be off topic also ... besides, there is no way to answer
Sep 11, 2024 19:52
you're dealing with larger pixels ... that means that you have to increase your distance from the display for the same visual quality
Sep 11, 2024 19:52
@GeorgeNtoulos For me there is no Reopen button. ... there is submit for review option when you edit your post
Sep 11, 2024 19:52
How does a square of 36 identical pixels look compared to 1 big pixel? ... that is entirely subjective and depends on viewing distance
Sep 11, 2024 19:52
it is unclear what is your specific question
 
Jul 28, 2024 11:46
without input ... what does that mean? ... what did you do?
 
Jul 23, 2024 18:13
look at the answer at electronics.stackexchange.com/questions/718707/… ... the relay does not switch the ground
Jul 23, 2024 18:13
I'm talking about the green wires ... do you understand what a relay does?
Jul 23, 2024 18:13
there are only two wires on the charger ... right now you are switching the ground terminal ... same with the load
Jul 23, 2024 18:13
switch the V + .
Jul 23, 2024 18:13
switching grounds is not a good idea ... there may be ground loops that bypass the relay
 
Feb 22, 2024 15:26
then your problem probably has nothing to do with the keyboard ... remove the keyboard and delete all code inside loop() and try again
Feb 22, 2024 15:26
it did not work is meaningless .. what happened?
Feb 22, 2024 15:26
I did that but it is still have the same outcome ... Serial.print is debug code, not the #define ... just print anything in setup() ... "starting." would work
Feb 22, 2024 15:26
put debug code inside setup()
Feb 22, 2024 15:26
this site is not a discussion forum.... all information must be in the question at top of this page ... use the edit button to update it ... right now, there is no code, no keypad, no Arduino
 
Feb 14, 2024 04:09
@MichalPodmanický please add that info to your question ... a comment is not the place for it
 
Jan 7, 2024 20:38
why do you require a microcontroller to generate the signal?
 
Jan 4, 2024 20:11
why not have the sensors in the jack ball? ... you really only need to identify the closest boule
 
Nov 9, 2023 11:27
are you listening to a radio that is tuned off station?

which part of your machine counteracts gravity? ... the picture shows two wheels, on one axis, separated by a gap, and a ball in between the wheels ... this same arrangement is repeated
Jul 29, 2023 19:49
you are trying to make yourself fly by pulling on your shoelaces
Jul 29, 2023 19:49
don't forget that for every action, there is an equal, and opposite, reaction ... your machine could be very dangerous ... if overused, it could push the Earth out of its orbit ... that could be mitigated by deploying the machines in pairs on exactly opposite sides of the Earth
Jul 29, 2023 19:49
didn't the pyramid builders use that machine to lift stone blocks?
 
Jul 24, 2023 16:20
your question says nothing about distortion ... please edit your question
Jul 24, 2023 16:20
if earth did not conduct, then there would not need to be any special electrical safeguards around swimming pools
Jul 24, 2023 16:20
where in the world are you located? ... neutral and ground are bonded at almost every breaker panel if you are in North America ... use a voltmeter
 
Jul 11, 2023 05:06
@Justin it's optocoupler ... optical coupler
Jul 11, 2023 05:06
feed the signal into a UART ... if the baud rate is set correctly, then the pulses should decode to a character

that is interesting about people not being offended ... maybe my view of religious people is skewed ... it did cross my mind that it could be the user's real name
 
Jun 1, 2023 22:30
what kind if wire are you using? ... your post still says dynamo
Jun 1, 2023 22:30
a dynamo has DC output ... you built an alternator
 
May 28, 2023 18:22
you figured out the voltage across the resistors ... now go back to the first diagram and add the voltage value into it
 
Apr 3, 2023 04:40
maybe, but you may not necessarily recognize it as being one
Apr 3, 2023 04:40
no, the system may have the capability to set the smart meter to match the mechanical meter at installation time ... then a visit would be made only if the customer complains about incorrect readings
Apr 3, 2023 04:40
if you refused to give permission to install a smart meter, then maybe the utility company installed one upstream and synchronized it to the mechanical meter
Apr 3, 2023 04:40
is the reading in the picture close to the reading printed on your bill?

the 5 second delay is for Serial.begin(DATARATE) to be delayed ... that may help with sketch loading
Mar 9, 2023 06:22
for "unblinking" an arduino ... set verbose mode for uploading in the arduino IDE ... compile an empty sketch ... copy the avrdude command line from the arduino IDE ... paste the command line into a cmd window (terminal window in linux) ... no more need to do the empty sketch upload from arduino IDE
Mar 9, 2023 06:22
try adding a 5 second delay at begining of setup()

@EricMarceau how can this post cause damage when you can't take it seriously after reading the title line
 
Jan 15, 2023 07:41
DC power supply that outputs 48 V, 20 A ... no, it outputs 48 V and the load can draw up to 20 A before the power supply shuts down, or the output voltage starts to drop
