I have a DHT11 temp/humidity sensor, a Flexiforce pressure sensor, and a PixyCam 2 sensor. I have three tutorials for each sensor that can turn on/off a LED light depending on the environmental/pressure/visual sensor thresholds.
However, these are done separately, in other words, once I tested out the DHT11 sensor, I took all the wires apart and started on a blank Arduino and blank breadboard.
I would like to incorporate all three at once. So an LED turns on if all three sensors satisfy a condition.
I tried doing this myself, but my Arduino and DHT11 sensor got really hot, which indicated to me that I was doing something wrong.
I'd love any general advice on how I can combine three tutorials into one breadboard... if that makes sense. I apologize if this is a stupid question but I'm new to this but yet I am very excited to start programming and making cool things happen. Please direct me to any resources that I may need or that you recommend, as I clearly lack an understanding of circuit design.
However, I cannot seem to find on Google information on "how to combine Arduino tutorials onto one breadboard" as I only get information on combining code/sketches.
Here are screenshots of the wiring diagram, if that helps.
Thank you so so much for any help or discussion on this.
Connecting all 3 sensors from the beginning and then start coding, testing, is the worst thing You can do!
Start connecting and running one sensor. Do this for each sensor.
When one sensor works, add the next sensor and make them work together. Repeat this until all sensors are up and running.
As suggested, test each sensor alone. Then combine.
Start by connecting all the 5V lines and GND lines together Then switch it on, Gets hot? check your wiring. Doesn't get hot, connect you O/Ps one at a time, Gets hot? Check your wiring and so on.
If you plan on doing this sort of thing more often I would suggest buying a bigger breadboard or another few of the smaller ones. That way you can set up each "project" on a separate board and join them as you wish.
Problem is, with Fritzing, people often give up when they can't find their board, and just plop an UNO in instead... I've seen it many times on this forum.

I see Your point. You're totally right. Fritzings ought to be filtered out from being attached.
Actually, it's the inability to develop an abstract (e.g. conventional) schematic, that is mainly preventing the OP from translating the circuitry to a breadboard... probably, they can't really understand why the wires go where they do. A person would go crazy trying to understand the design logic behind every rat's nest layout, since they are often different every time.

I fully agree. All those Fritzings and no information about the powering connections. So often information not mentioned is the reason for the trouble.
One Youtub guy, "drone bot shop", launches lots of videos and uses that bloody 9 volt fire alarm cell connected to Vin. Then people hook up lots to the poor 5 volt pin of the Arduino, over and over again. I kicked the leg of that guy.
My problem with Fritzing LEGOs is that we here are mostly engineers, technicians and experienced hobbyists. We speak "Schematic". At a glance of a schematic, I can immediately, or with a little study, understand what the circuit is supposed to do. Sometimes errors are obvious at that point. With a Fritzing LEGO, I won't take the time to trace the wiring to make a schematic that I can understand. I don't think I am alone in this, which is why I said that a schematic will get more cogent responses.
I fully agree. Why would I read "poetry" and draw a wiring? Often the issue us found in what is not told.
Fritzings are readable if they are UNOs that I use. Else... ghostpins...
