Ultrasonic Range Sensor Touch-Free Input Tutorial for Arduino / ESP32
HTML-код
- Опубликовано: 16 авг 2024
- This is the second video in a series in which I'll be considering various methods that can be used to replace a traditional Arduino button input with a touch-free interface instead, requiring no physical contact. This is just one possible consideration of how you can make an escape room (or any other public-facing Arduino interface) more "Covid-secure".
In this part I'll be looking at an "Ultrasonic Range Sensor" HC-SR04 component, which can be easily purchased online for only a dollar or so from, e.g. www.banggood.c...
It's a cheap, readily-available module that's easy to wire and code on an Arduino, ESP32, or other Microprocessor.

If you'd like to support me making more video tutorials explaining how to use tech in escape rooms and other playful settings, please check out my Patreon at / playfultech , where you can also find code downloads, wiring diagrams, and additional resources for this and all my other tech projects.
Maxbotix also make some very nice, clean (they have amazing filtering/processing/discrimination built in) accurate and easy to use ultrasonic sensors, not cheap but they do all the filtering/measuring in the sensor, freeing up the Arduino and can also be polled so multiple sensors don't interfere with each other.
Esp32 mentioned which is 3.3v logic. I suspect some adjustment is needed for that however I think there is a new version of the sensor that works at both logic levels
where can i find the ultrasonic library?
can you help me how to answer yes or no questions in a web application using ultrasonic sensor? can you help me with the code using arduino ide? I'm using ultrasonic sensor and esp32
did you have any answer?
I'm struggling
Can I use same arduino nano code for esp32
Bruhh what project are you doing?
