Oct 23, 2012 · The goal is to have the LED blink quicker when an object gets closer to the sensor- (PART A) IF nothing is closer than 150 cm, the goal was to have it pulse… I have worked on this since the previous inquiry for some help.

Apr 27, 2024 · The ultrasonic sensor will sense a presence, and it will turn the whole system on The DHT11 will sense if the temperature is below or above 40 degrees Celsius. If it's below, the heat pad will turn on, else, it will turn off.

Jul 7, 2021 · Create a variable that is your distance you get from the sensor. Write a regular if loop based on that variable comparison. Hope this gets you on the right track.

Jun 28, 2022 · So in this blog, we learn about what if else condition is, how to use if else condition in Arduino, we see the application or use of if else condition through a push button and led also with another example with ultrasonic sensor and led. we also have seen the ternary operator, what is ternary operator, and how to use the ternary operator.

Apr 6, 2023 · In the loop function, use the distanceRead() function to get the distance in centimeters from the ultrasonic sensor, and store it in a variable. Then, use an if statement to check if the distance is less than a threshold value (in centimeters).

May 2, 2024 · Learn how to use the ultrasonic sensor (HC-SR04) with Arduino. This tutorial will teach you what it is, how to assemble the sensor on Arduino, and, at the end, you'll implement it into an alarm system project.

Feb 27, 2014 · I also added an else statement so that if it does not meet that criteria it returns it back to 0. Finally i put in a delay so it doesnt happen to fast. A better way to add a delay would be to use millis.

Nov 30, 2020 · my problem is getting a working If statement to tell the ultrasonic sensor to active the pump when someone is within range. My current code can be seen below. Thanks to anyone who can help!

Sep 7, 2022 · Is there a better way to do this with an ELSE statement? I want to capture the parameter where the code controls the specific parameters of >5 and then <or=5. Also, my next thing is to pause, and reverse the motor if after 1 second, the sensor still sees an object <=5.
