Nice Video. After killing a few of these modules while soldering pad A & B I cut a small piece from resistor and place it on those stupid pads then soldering becomes easier.
Thank you SO MUCH for posting this video. Can this switch be used in place of a mosfet to switch on and off a simple circuit, with the only other components being an led and a power source (and possibly a resister)? I hope to make a tiny light source to place inside a matchbox/hot wheels car that I can activate/deactivate by just touching the surface of the car.
New camera? Nice filming, soldering while filming - difficult to say the least and you pulled it off wonderfully! Nice topic as well. For a change, I have one of these....now I have an urge to go get it and experiment!
Not a new camera (I wish - I've been overdue for an upgrade but it isn't feasible for another little while at least) but I used the macro lens that I use for thumbnails for filming.

Hi,with the sensor, I'm trying to power a mini bluetooth/amp module with a 3.7 lithium with charge chip. The sensor shows the 3.7 on my meter, but when I Solder to amp board, it cuts on and off. I'm thinking it's a ground issue? The sensor gets the vdc and ground from the charge board, the amp gets the vdc from the i/o on the sensor and I've tried different amp ground locations. The amp cycles on and off. I have B jumped on sensor.
In Momentary / High Output 00 (1st) mode sensor is off after 12 seconds even when touched. Please help me that we do in ttp223 that it will work as long as 1 stay in touch.
Why my ttp223 sensor getting triggered by anything it touches, even if i put non conductive plastic plate on it, it is triggered, even touching it to wall triggers it.
Works great on the inside of my plastic case containing some electronic components including an Arduino Nano. I am presently fixing the TTP223 to the inside top of the case with electrcian's tape stuck to the component side of the switch. Do you think I could glue the touch side of the switch to the case instead?
Do you know if there is a way to make the output signal ground. I'm trying to integrate this into my car audio build. And all of my relays are for 12 volt. So I was thinking if possible to do a ground signal being sent
can you please confirm this, The TTP223 capacitive touch sensor does it have built-in timeout mechanism? the reason i am asking is i am trying to use the TTP223 in a way when i touched and keep touching it i want the LED stay ON while my hand touching it and when i release i want the LED to be OFF. i have tried it but after like 7 seconds the LED goes OFF even i am still touching the sensor. Can you help with that?
hello!, Is there any way to bypass the auto calibration function? after 8 secs aprox the snesor re-calibrates and it no more detects the object. Thanks!
Hi, I’m just curious, will this switch support a higher load as a CREE LEDs flashing??…noticed you used a regular led which has a lower load…thank you.
Great video! I am trying to power a DC: 3,5-9V mini water pump with a 18650 3,6V Battery. What MOSFET do I need to use to make the TTP223 work? Thanks!
thanks for the video ,but my problem , the switch does not keep the status "on" , more than 7 sec in the default config , have you tried to leave your finger on it more than 10 sec?
I have seen somewhere that it re-calibrates its detection parameters every 7 seconds. So if you keep your finger for too long , it will re-calibrate with the presence of your finger and turn off. I have ordered one to confirm what I just said, but it seems to consider "on" in reference to a change of capacitance relative to the calibrated off value.
Hello friend, thanks for the video, I have a doubt, over the pin I/0, i want to use with ardino esp8266, but, when i near my finger, the pin i/o dont remain with the VCC voltage, if no the voltage is less. I am using like a input in a pin of the esp, but this pin also have the configuration like a pull down. And you know that the esp receive a input up with 3.3v. Have you a practice example aver that please. Thanks advance
can you please help me? my ttp223 touch sensor light is always on when i connect the vvc to 3v on nodemcu and it gets so hot also the touch wont work when i touch it and the led is always on too. whats the problem?
Super cool video, didn't see the 9mn go. As said below by others you explain very well. Now that might sound weird but would this switch work with let's say.. My tongue ? OR is it finger/skin only?
Thanks for the video, it is the best of about 5 videos I have watched on the topic. Can you please tell me if there is a way to hook up the TTP223 to a piece of metal so that the metal becomes the touch point? I know it can be done if hooked directly to the transistor and deleting the TTP223, but then you have to touch two pins on the transistor at once. I am hoping to have one touch on/off. Could I just solder the TTP223 to the metal or just add a very light capacitor to the appropriate location?
I don't see why you couldn't just scrape the solder mask off the touch pad and solder to it, it would just extend the "antenna" so to speak, give it a try!
Its the solder dot (via) in the corner, or solder to the non-ground side of the sensitivity cap contact. watch those East Indian vids of using a device; you know, no-circuit board solder design.
Thank you for this video, it was really helpful in figuring out how to work these. I'm having trouble using one as a switch for my Raspberry Pi 4. I took a power supply with a hard switch, removed the switch and swapped in the touch capacitor switch. My voltmeter reads that I'm getting ~5V out, but the Pi won't turn on fully. It has a solid red LED with no green, which from my understanding means it's not getting enough power. If I plug in a normal unspliced power supply (I have a few) it works fine. I'm assuming the switch is limiting how much voltage is going through, but you said it's rated for up to 5V so I'm not sure. Any ideas?
Oh careful, it may not work as a hardware switch because I think it is current limited! You can use it to interface with pins on a microcontroller but I don't think it can switch enough current to supply a RPi!
I would have to look into it....however simple you think it may be, it's far more complex than that. This is made to emulate a regular button, it's nowhere close to a touchscreen.
Like I said, the tap on the smartphone is read out like an XY coordinate and not like a button press unfortunately. It can definitely be done but it will be very complicated.
Hello, I need help. I don't know much about electronics but i am a guitarist and i am trying out different type off killswitches that momentarily kill the signal of the the guitar to get a crazy stuttering effect. I have learned the hard way, that i need on-switches to kill the signal and not off switches. Now i try to develop a killswitch that isnt your regular button or toggle switch but a touch sensor because i hope to get the stuttering effects much faster. Do you have advice for me?
You can not connect this switch shown in the video to a very high voltage, so if the power rating of your circuit is very high, you need a few more components.
Hi. First, thank you for the video. Second, how can I use this device to reset a ZX Spectrum or a Commodore 64, using the reset pin of the CPU? That pin is active low, btw. Ta.

This video is super helpful I’m new to this type of world and I don’t know much but I have two questions if you guys wouldn’t mind me asking. 1: I notice the pcb has three connections and I was wondering if it would still work if I spliced it to a custom built pc power on button cable which only has two wires and I believe run at 5v (correct me if I’m wrong) 2: I’m assuming since you put it through a case and it still toggled would putting a sticker over this still trigger the switch ?
@@SimpleElectronics Actually no,I bought a strip of them like you have, but I used my homemade hotplate to remove some of the chips which was cheaper than buying them as I needed two for a project !
I believe that would be no capacitor. Adding additional capacitance would decrease the sensitivity, minimizing the distance the sensor can read. The sensitivity cannot be increased without changing the geometry of the device; in other words, the device with no additional capacitor represents the highest sensitivity/maximum distance the sensor can read given the shape and positions of the parallel plates in the device. Someone correct me if I'm wrong.
I have seen other videos attach a wire and plate to external contact causing a deeper field of non-contact area from 1/4 inch to inches. I assume larger area equals more electro-static charging potential.
I think this is wrong. You connected the cap to the connection for external switch! The cap needs to replace the SMD cap you still have untouched. This is why your test is not successful in the end of the clip.
It seems both the cap that's already there and those two open pads are in parallel with the touch pad, so they would both adjust sensitivity, but for sure you can remove the cap to modify the sensitivity moreso
Sir, you explain very well. The way you speak makes the subject easy and interesting. All the best!

Hi... good video. Does the capacitive switch work under 2mm acrilic layer? - inside a plastic case
Yup! Should work just fine!
Did you ever get a video that shows the proper capacitor and it's range after that?
The ESP-32 has pins which can be used for this purpose as well.
But TTP223 can be triggered from distance 0,5 meter, but the ESP-32 touch pin must be touched. This is the main and significant advantage No?
