Sir, in your first step when you cut one of the two wires to connect in the relay be sure you cut the right wire. This is important for safety reasons. One wire is ground and one wire is hot. the ground wire should never go through a switch or relay, otherwise you can end up with dangerous voltage on the appliance when it is turned off. You can tell which wire is ground because it is always marked somehow. On a lamp cord if you look closely you will see or feel small ridges on the ground wire side. This is connected to the wide pin/spade on the plug so you cannot plug it in wrong. Cut the smooth side of the cord only, to be safe.
I have watched your full explanation which has been done very clearly. I wish to use this without Micro controller Adruino and in the direct mode...I want to act the touch pad as toggle switch..i.e....touch to on and again touch to off...with any time of gap between on and off. Just like we switch on some load and switch it off whenever we wish. Once again, you can switch it on by touching it and switch it off as and when needed..is it possible by adding any component to this PCB...???
@@robojax Yes, I have purchased a wrong item...This board can't be remodelled somehow..???? I should have enquired and seen many videos before buying it. Actually, I should have bought the Brown Coloured PCB wherein provisions for 2 jumpers are there...Which help in using the board in 4 configurations plus it has a slot for extra condenser also for sensivity adjustments. Price is more or less same...The company which supplied me hasn't given any support... That's very bad...😢😢😢
In the setup without the Arduino board, the touch sensor works just like a push-on button, now if I want to make the touch sensor work just like a regular on-off switch do I need the Arduino to do that?
Yes you do need Arduino to so it keeps the status of your touch. Watch this video and you will learn that. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Nqh1vYQEEjs.html
hola una pregunta .. esa informacion no se puede grabar al touch sensor ? osea se puede despues que hacemos esa configuracion sacar la placa arduino ? o solo funciona con la placa de es a manera ?
Hi, thank you very much for your lesson. My circuit works great. Is it possible for you to provide the arduino code for the circuit with 2 capacitive switches, 2 relays and 2 lamps with one arduino board? Thank you so much for your help. Svetlana
You are welcome. Here is touch for 4 channel with relay ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4kVhG0OpCf8.html The best thank you for me is to not skippin the ads and Subscribe 🔔 to my channel, like 👍 the video and do not skip the ads.. It is greatly appreciated. 🔔 😊. I will reply to all Subscriber's 🔔 questions. So make sure to Subscribe.😊 .
this is just switch. and switch means ON and OFF. Here is Arduino based dimmer ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zJQf6bNodhE.html and yes you can use the touch switch to make the light dim. Very interesting project.
Hello, I added link to the 5V relay in the description of video. No you don't need second power source. the same 5V can be used to power them. here the links to purchase. relay has no model. it is called 5V relay module Relay from Amazon USA: amzn.to/3p1n0iL Relay from Amazon Canada: amzn.to/2Lru1Kp TTP223B from Amazon USA: amzn.to/3a8yE6y TTP223B from Amazon Canada: amzn.to/2WdY22o
Hi Robojax, I stick a TTP223B sensor to a piece of glass and would like to have that glass act as a switch. The problem is when the sensor touches with the glass (without my finger touching the sensor or the glass) it sends a high signal to the Arduino board. I have also tried connecting the signal pin of the sensor to an analog pin in the arduino and the Arduino reads 1023. I have also tried connecting the GND of the Arduino board to my house's ground but it still sends a high signal when the sensor touches the glass. Do you think this is the way the TTP223B should work or is there something wrong with the sensor? Thanks.
HI, Interesting. This module uses capacitive touch to detect touch. So the surface area where you are supposed to touch determine the proximate value for the capacitor and it has been calculated to work that way. When any other object comes in contact with that plate (touch area or electrode), it changes the capacitance of the electrode and as a result it triggers the touch detection. So if you can, you should draw the schematic diagram of this module and find out the which resistor or capacitor to change and it will work. here the datasheet for this module: infusionsystems.com/support/TTP223.pdf and you can see it says: Sensitivity can adjust by the capacitance(0~50pF) outside.
Yes you can. As soon as your finger touches, the switch/relay will activate. Once you remove finger, switch/relay will get disconnected. So if you keep for long period of time, the switch will stay ON until you remove finger.
@@robojax thanks for the reply. Now I have new problem. The relay only turn on once and doesn't turn off when I touch capacitive touch switch again. If i add 10 microfarad capacitor will it fix this issue?
Hello, My electronic assembly and your code (I copy / paste) code does not work. I use a Velleman VMA305 and it does not work. It's the problem ? Also, you use which component (values ?/Model?) on the breadboard between + and - ? . Thanks for your help.
Does the module light turns ON? if not check wires. if yes. than check your relay by connecting the input of the relay to instead o connecting to touch module, connect it to GND to see if it turns ON (or to 5V if your relay is high trigger). The component has been explained at 5:38 and it is a capacitor to filter noise. But it is should not affect the module.
sir i wanna on output with help of sensor and when I sense again sensor the output will be off, mean latch krvana h , and 1 bar sense s on or dobara sense s off, was that possible?
Sir my touch work is not properly working one time touch relay many time connect and disconnect bulb light biking speedily I use 50 volt and 22 uf capcator please solve my problem
When I touch so pulse not Gernet properly and relay green led not off problem suddenly duering the touch the pade and Some time I touch pade it work proper
