SIMPLE Arduino Float Switch Tutorial!!

Very simple Arduino float switch tutorial to light up an LED light.
Copy and paste code into Arduino IDE
Code for project:
------------------------------------------------------------------------------------------------------------------------------------
//Set the LED light to pin 8
int LED = 8;
//Set the float sensor to pin 3
#define Float_Switch 3
void setup() {
// initialize digital pin 8 as an output.
pinMode(LED, OUTPUT);
pinMode(Float_Switch, INPUT_PULLUP);
}
void loop() {
if(digitalRead(Float_Switch) == HIGH)
{
digitalWrite(LED, HIGH); //Turn LED on
}
else
{
digitalWrite(LED, LOW); //Turn LED off
}
}

I'm sorry, I just wanted to clean up your code a little bit. int LED = 8; //Set the LED light to pin 8 int float1 = 3; //Set the float sensor to pin 3 void setup() { pinMode(LED, OUTPUT); // initialize digital pin 8 as an output. pinMode(float1, INPUT); } void loop() { if (digitalRead(float1) == HIGH) { digitalWrite(LED, HIGH); //Turn LED on } else { digitalWrite(LED, LOW); //Turn LED off }

im subbing cause its simple yet very useful. great job. i love the music also.. not annoying.. also the way you presented it was clear even if there was no voice over. greatjob man thanks

[@christopherselectronics7153]

Thank you for subbing! I’m glad you enjoyed the video!

[@connorbannochie9014]

Thank you Christopher!

[@basted1598]

This video is legit, but it only works for simple check of the float switch. Still it works

[@electricalcoder3025]

awesome and pretty cool smart work christopher.👍👌👍👌👍....keep creating.....as we share the same passion and channel contents thats arduino and programming i will suppourt you as much as could... and i SUBSCRIBED yours too ...anyways ALL the very best dude

[@christopherselectronics7153]

Thanks a lot, I appreciate the support. I subscribed to you too. You have some awesome content. Nice job!!

[@leokaban461]

where can i download Ball Float Liquid Level Sensor library for fritzing software???

[@apo.exoworlds]

Great content for those new to Arduino, tnx! If you have time to spare, I would love to see this used in an automated irrigation system (I'm asking this for a friend 😁).

[@christopherselectronics7153]

Thanks, glad it was helpful! I am always open to video suggestions. Would you mind letting me know a few more specifics about what type of irrigation system and for what purpose? Thanks!

[@emilperijocable]

Great video Chris. quick question, do you have any experience with that type of sensor? can it be submerged all the way for longer periods of time? Cheers

[@christopherselectronics7153]

I have used them, but only above water/ on the surface. I do believe they can be submerged, but I am not aware to what depth. It might be helpful to check data sheets or manufacture specs to be sure

[@brianalaba970]

what if i used buzzer or horn instead of bulb what is the code? and the diagram

[@gitanjalivijaydevanand3957]

Hi! Wonderful job!!! I am really looking forward to using this for my project.... Is it possible to connect three float switches to a single arduino...if so can u explain how it can be done?

[@christophersaquariums659]

Thank you! Yes, it is certainly possible to use three or more float switches. If you intend to have each float switch control one led, simply follow the steps in the video, but for each led and float switch, plug them into different pins. Then if you understand how the code works, simply define each new led and float switch, define the pins, and rewrite the loop for each new float switch (just remember to change its name for each loop). If this doesn’t make sense I can send you an example code.

[@gitanjalivijaydevanand3957]

@@christophersaquariums659 Thank you very much for your reply. Will try to follow the steps that you have mentioned...

[@christopherselectronics7153]

Gitanjali Vijaydevanand I’m glad he could help! Let me know if you have any other questions.

[@cake2277]

Is there one for the software?

[@miteshbhaliya2561]

Hello cristo ... i got error during upload of the programme ..its showing ( micro names must be identifiers)

[@christopherselectronics7153]

I haven’t had that error before. Make sure you only have the code copied and nothing else. Also, try searching that error in an Arduino forum online and see if there’s any info on it. Sorry, and I hope that helps!!

[@scarlettirons6790]

Where did you get the water level sensor from please?

[@christopherselectronics7153]

I bought mine off amazon. I can't post a link, but if you look up "float switch", you get a lot of results to chose from.

[@lukemark157]

Hello bro, can I used piezo buzzer for warning? If it is yes, how? Thank you

[@christopherselectronics7153]

Yep you can! Replace the led with a buzzer and it should work. No code changes needed

[@amkkosa]

Where can I buy such a sensor? I did not find any which works on 5V on eBay...

[@christopherselectronics7153]

Here is a link to some on amazon. These are what I used: www.amazon.com/Anndason-Pieces-Plastic-Switch-Liquid/dp/B07211T6Y6/ref=sr_1_3?crid=3VQOMBUN2HFMP&keywords=5+volt+float+sensor&qid=1641770367&sprefix=5+volt+float+sensor%2Caps%2C76&sr=8-3

[@vhonthugzadventures]

sir where did you order/buy your floater switch

[@christopherselectronics7153]

I bought mine off of amazon

[@vhonthugzadventures]

@@christopherselectronics7153 thank you sir,

[@user-zm5so7rm8z]

No pull up resistor?

[@christopherselectronics7153]

One isn't necessarily needed, but in practice a pull up resistor would be used. I was trying to keep everything as simple as possible!
