How to connect ultrasonic sensor to arduino uno Esp8266

-

i little bit confusion how connect echo , trig pins of ultrasonic distance sensor arduino uno , esp8266. made connectin between arduino uno , esp8266 , connecting wifi netwok. want read sensor data.

anyone me regarding issue

thanks in advance

which of 2 want connect sensor to?
actually doesn't matter - take 2 pins, echo , trig, tell sketch ones have, , you're go. uses exact same code both processors.

hi new arduino , trying write code of temperature controlled fridge can adjust pot , temp in fridge changes lowest setting -15 , highest setting 30degrees. the temp drops below input pot im trying make compressor turn on , light show compressor on. new @ , im still not quite sure im doing. error below keeps popping , im not quite sure whats wrong code. im hoping on close path how should have done it, how fix error appreciated. arduino: 1.8.4 (windows 10), board: "arduino/genuino uno" c:\users\admin\appdata\local\temp\ccfcxdpc.ltrans0.ltrans.o:(.rodata+0x6): undefined reference `print::write(unsigned char const*, unsigned int)' c:/program files (x86)/arduino/hardware/tools/avr/bin/../lib/gcc/avr/4.9.2/../../../../avr/lib/avr5/crtatmega328p.o:(.init9+0x0): undefined reference `main' collect2.exe: error: ld returned 1 exit status exit status 1 error compiling board arduino/genuino uno. this report have more information with "show verbose output during comp
