I want to make a pressure sensor with an LCD display. But the microcontroller and Arduino ICD cannot be imported correctly. What is the problem? My interface selection is correct (Arduino Uno). Is this error related to the circuit wiring and program code? Or is it just a problem with the Arduino ICD software I downloaded?
Please test the LCD and pressure sensor separately with the Arduino.
Welcome! Yes, it is where the purple wire crosses the violet one and connects to the orange one. As for the software swap lines 233 - 250 with lines 34 and 45.
Interesting project but we are not a free design or code writing service. We will be happy help out with your design and or code but first you have to make an attempt to design it, write it, post it and explain what is not working properly.
If there is hardware it is always best to post links to technical information as there are many versions of the same or different items. Since we cannot see your project, my eyes are to weak, you need to post using the language of electronics, an annotated schematic (best) or a clear picture of a drawing. Pictures never hurt. Frizzing diagrams are not considered schematics here.
