Your code is full of delays, this is a common beginner mistake. 'Delay' means 'do nothing' for some time period. Doing nothing includes not doing the ultrasonic scanning. You need to understand the principals of millis for timing, state machines and non-blocking code. The tutorials that will help you are these (and maybe some others I didn't think of): Using millis for timing Demonstration for several things at the same time Finite state machine tutorial [image] Timer counter state change toggle FSM - all at once Tutorials There is a recurring theme of people new to Arduino and/or microcontrollers not grasping the concept of putting what I call ‘building blocks’ of code together to achieve some goal. These short sketches are an attempt to offer some examples showing how small pieces can be used in concert to build up larger, more complex sketches. Thanks to @PerryBebbington and @ballscrewbob for support and input. You made it better. The examples will illustrate: • Doing ‘several things at once’ • pitfalls of … And please, edit your code to use code tags; select the code in your post, click on in the tool bar.

Thnk you ..im learning millis right now

You might also find this useful: [image] Flashing multiple LEDs at the same time Introductory Tutorials Introduction A common question is to ask how to flash 2 (or more) LEDs at the same time. Typically the person asking will be using delay and will be experiencing the main problem with delay: it blocks and stops anything else from happening. This tutorial contains several different approaches to the problem of flashing 2 or more LEDs at the same time with independent timing for each LED. The basic principles for each can all be adapted for other situations requiring multiple timers working inde… Although it is about flashing LEDs the principles are the ones you need to learn.

So why is the topic marked "solved"?
