Incorrect Auto Route for 7 Segment Display
Looks like the part doesn’t have constant #ing and might be confusing, so I think you have to fix the part. Right-click the 7-seg and Edit Go to BB view and click C in the table Now go to PCB view....

Hello, I’m already a user of arduino and IOT devices but making a pcb is new for me. I tried to make a small pcb for my IOT system. It contains a ESP8266-01, DHT22, LDR (includes 10K resistor) and...

The PCB routing looks good but I can not see any reason why you would have both a 5V regulator and a 3.3V regulator. Further more you have the 5V regulator output going into a voltage divider made up...

Opps I made a mistake with the SCH view. I made the leg connects a tiny red dot on the end when the leg should be all red - easier to see if it’s not connected -. So right-click remove the part from...

1 use the 5V for all of my sensors on the board. (currently only 2 but maybe in future) and 3.3 for the ESP-01. I was using ESP-12 at first but after some trouble i decided to choose ESP-01. did’t...

I found I had recently emailed it to someone and that copy loaded. Maybe I will look at the differences to see what FZ did to the file.

You currently have two sensors, 1 being the LDR which would be fine running off 3.3v and your Humidity sensor which is also fine to run off 3.3v so unless you know you must have a 5v source I think...

It’s 3 posts up in the same place - v1.1 - SCR TO220. It has the same name, and the only difference is that the legs in SCH are full red not just the tips so you can see it go from red to green when...

i switched to ESP-01 because of the SMD. But i already have 2 nodeMCU’s so i think i just solder a nodemcu on my pcb.

I downloaded that file and imported it and the pins are red for their entire length, so you probably still have the old part in the bin. It’s not important as it’s cosmetic and will still work.

Thank you for your patience, I am totally new to this software and know almost nothing of electronics!

could you check if i connected LDR and DHT correct?NODEMCU IOT.fzz (28.1 KB)

Your only ground connection to the NodeMCU board is through the button which is not the best idea. You should have at least one trace connecting it directly. Even if it’s just putting a trace between...
