Is there a possible way to combine the code of esp8266-01 and ultrasonic sensor in an arduino uno??
Please i need a help 
It will be impossible for us to help you with so little information.

It will be impossible for us to help you with so little information.
So i use esp8266-01, ultrasonic sensor and led lights and i use arduino uno, the concept is when the ultrasonic is sense a short distance the light will on and then will send a data in a web server and store it to database using esp8266 GET method
So i can do the esp8266-01 send data to web server via GET method and a little php but the MCU of the arduino is out or removed but can't upload a syntax or a code which is for ultrasonic sensor without the MCU of the arduino uno
And then the other thing is the board when i upload a code in esp8266 I use esp8266 generic board but I know that ultrasonic sensor code is work base on the device that you use like mine is Arduino uno/genuino board
By the way I'm a beginner in arduino and other hardware hope you help me
