Taking another look at the TTP-223 touch sensor module. Making the module breadboard-friendly with a new Dupont pin header. Modifying the module to enable toggle mode.

May you show me how to connect one of these please and thank you, message me back
Nice video can I use this fr a drum machine project?
Is there any way to toggle ttp223b green led ?
@Julian Ilett If the receiver sends an acknowledgement packet, does the sender send receipt of that acknowledgement? and the receiver receipt of that receipt of acknowledgement? 😛
i purchased some of these from aliexpress a few years ago and just now found a practical use them… just to test them i connected one to a USB cable on my computer, with a male/female connector, then just wired red to vcc and black to grnd…. get a red light, not green like every site says i should get…and the light doesn't change when i touch it – long touch, short touch, back front, nothing… so figured it was a bum one… got another one… same thing… got ANOTHER one – same thing. so clearly i'm doing something wrong… just to test to see if they even recognize a touch, not even wiring a circuit or anything… am i just stupid or something? what's the deal? any idea?
Can we use this to 5 mm glass
Julian, I have faced the same "toggle/momentary" dilemma (may be too strong a word!) as you do. I decided to keep the hardware switch in momentary mode, and perform the latch function in a couple of lines of code instead. Advantages: you can set the start condition of the switch during a software reboot. You can override the value by program if you need to (for example temp over-range forces fan on, regardless of switch state), or you might choose to "lockout" the button's function during certain program phases or times, you can implement dual functions by a short-press, or long-press. I notice a lot of the so-called toggle switches in my car work this way, too.
Meant to ask on a previous vid, what's the capacitor doing on the transmitter board?
The trick with solder sucking a plated through hole is to hold the board vertically and place the sucker on one side and the iron on the other. That way you can keep the heat on and get a better seal with the tip of the sucker.
I'm still struggling to understand the human involvement here. Why not fully automate this so when a humidity level is reached the fan turns on automatically? You wont always be at your desk, or awake… fun though.
goooooooooood morning Juliet
Never understood why they solder them pins in when must time you need straight pins.
@Julian Ilett I’m curious if the Active Low / Active High pin setting also determines the power-on state? eg. If the initial power-on state is Off (seems logical to assume), then you’d also assume this pin might control if the output is initially high or low after power-on initialisation. In which case this pin would still be relevant even with Toggle mode selected. ie. On power-up do you want the fan to default to On or Off?
Wouldn't an ESP32 with an "external' antenna be a better idea?
You'd get the extra bit of range you need and built-in touch switches.
Comment #31, Well done.
I'm loving this shed remote control series
You should have the unit in the shed report back the battery level once or twice a day. I know you're planning on putting a big battery out there but it's going to get low at some point
