Thank You so much @BasonTech for the debounce code and the wonderful explanation.

[@BasonTech]

Great I could help! Have fun with your projects! 😃

[@dhruv_195]

I have watched so many tutorials on Arduino but no one has ever talked about millis() function. I always wanted to use the concept of debounce in my project but I didn't know how to. Thank you so much for the help.

[@BasonTech]

Great to hear! This tutorial of mine also uses millis() so might be useful to check as well 😃 arduino-tutorials.net/tutorial/long-press-button-on-the-arduino-with-millis

[@markolengyel6254]

Awesome, thank you.

[@BasonTech]

Thanks! My pleasure! 😃

[@LuisLopez-cv5ew]

Thanks for sharing that nice example also the sensor alone can made the same and soldering pin 4, 5, 6 of the CMOs together acts as a toggle switch.

[@BasonTech]

Hi Luis, thanks for sharing! 👍🏻

[@First.Last.99]

Amazing tutorial :) thank you a lot. Have 20 these similar touch sensors will do a work clock for me with pause :)

[@BasonTech]

Nice! 😃

Hi there! Can You attache this zensor to a glove .. so,when i press with the glove . I will like to show me o a screen the force with witch i press mesured in kilograms You think that could be posibile ?

[@BasonTech]

That would be a bit too much to ask of this basic sensor. I can't think of another sensor which can achieve this.

[@Fasmaee]

Hi, not sure why, i have included the simple code in IDE, yet when i compile it it gives me error codes This is the code, which i think is identical to yours. What am I missing? void setup() { // put your setup code here, to run once: pinMode(5, INPUT); pinMode(LED_BUILTIN, OUTPUT); digitalWrite(LED_BUILTIN; LOW); } void loop() { if(digitalRead(5) == HIGH) { digitalWrite(LED_BUILTIN, HIGH); } else { digitalWrite(LED_BUILTIN, LOW); } delay (100); }

[@BasonTech]

The compiler is right, there is a small typo in the code. Look very careful for all commas, semicolons etc. I am sure you can spot the typo 😃

[@Shri-yf7yc]

Can you list the components used

[@BasonTech]

It's listed in the video description 😃

[@luluvahhuzaifa7200]

How would you use this on an added LED

[@BasonTech]

Sorry I don't understand your question. Add a LED to?

[@ramsc5813]

Hi there, i have a question. I guess you know the game Tablesoccer. I am a professional player and it can get hard with speeds up to 80 km/h to recognize if the ball went into the goal or not. Sometimes it bounces out right away and it looks as if the goalie blocked the ball although it was a goal. This is a problem in tournaments. My thoughts were, if it is possible to have a soft sensor-mat which you can glue to the walls inside the goal. Do you think this would be possible in a way, that it is extremely accurate? Thank you :-)

[@BasonTech]

Hi, I don't think this is the best sensor to use. Speeds of 80 km/h will completely destroy the device, and besides it is a captive sensor so it does not work on a ball. My suggestion would be to use a laser on the goal boundary. I've found this video of people who already made such a system: kzbin.info/www/bejne/q5-7hmijbKqkl7c

[@yusufyusuf7919]

Thanks man this helped

[@BasonTech]

Glad I could help! 😃

[@toritoxx129]

can the sensor be activated by anything? (like you gat a pen or a toothpick, will it turn on?)

[@BasonTech]

Unfortunately not, this sensor is capacitive which means it needs to be touched by conductive materials which allow current to flow through like our finger.

[@toritoxx129]

Ok, thanks. This was really helpful

[@BasonTech]

Great! Glad I could help 😃

[@stephen285]

thnks for the vid ---- can they detect velocity, how hard you are touching?

[@BasonTech]

Not really, this is a digital sensor, not analog. You can of course detect how long it was pressed.

[@smurf6595]

Any way I can wire up one of these to act as a PC power button?

[@BasonTech]

Sure! You'll then need a relay to switch the PC power. This relay is switched by the touch sensor.

[@EnergySeeker]

is there a touchless sensor ? am trying to find it

[@BasonTech]

Not that I know. There might be a sensor which can detect a certain resistance when something approaches the sensor. Maybe you can do something with a LDR or PIR?

[@EnergySeeker]

@@BasonTech thanks for your fast answer

[@hi_beemo1808]

5:50 so that means if you hold touching led will blink?

[@BasonTech]

It will not since the if is not triggered when the sensor is LOW.

[@gofarperdana2659]

Why my sensor LED turn red instead of green?

[@BasonTech]

As far as I can see there is only 1 LED on the PCB. Therefore I guess the manufacturer used a red LED instead of a green one.

[@gofarperdana2659]

@@BasonTech Its green sir, mine is red. lately i just know that i burnt my sensor by plugging it onto 5V Pin.

[@BasonTech]

Interesting according to the specs it should be able to operate between 2V and 5.5V

[@gofarperdana2659]

@@BasonTech In my opinion its better to use the 3.3V before continuing to higher volt like 5V etc to prevent burnt the sensor

[@ahmedfayez4596]

Hello Sir, I have this sensor and i need some help please. I need to control two LEDs with this sensor. 1 touch turn on or off LED1, while double touch turn on or off LED2. how can I do it?

[@BasonTech]

Hi Ahmed, what have you tried already and what issue did you ran into?

[@ahmedfayez4596]

@@BasonTech Acutally I didnt even try because i dont know how am going to write the code. If you can make a video it would be great Thanks for replying

[@BasonTech]

The videos are already there 😃 I've made tutorials on LED, long press and the touch sensor. Combine these and you should have what you want.

[@ahmedfayez4596]

@@BasonTech I watched the video and its really helpful but still i cant program double touch and single touch. What i want to do is, single touch turn on or off led1, double touch turn on or off led2, then long touch to turn on or off led1 and led2

[@BasonTech]

This is still the same as the longpress video with an extra state. You need to measure the time between taps to determine if it single, double or longpress.

[@mohammedahzan7685]

WHAT IS THE USE OF THIS SENSOR

[@BasonTech]

for example: you can use it a a button without having moving parts

[@6반5번김서윤]

What is that touch sensor's model name?

[@BasonTech]

Hi, in the description of the video you'll find all the parts used in the tutorials. The sensor is this one: arduino-tutorials.net/r/0cVKLS 😃

[@6반5번김서윤]

@@BasonTech Oh thank you~

[@amirabouzour9510]

Where is the code?

[@amirabouzour9510]

I cant find it on the website

[@BasonTech]

On the bottom of arduino-tutorials.net/tutorial/reading-touch-sensor-with-arduino you see a link to Github 😃
