This touch detection IC is designed as a substitute for the traditional direct button key with a diverse pad size. Note: This product is in blue colour. I do not have these modules, but if I saw correctly the unpopulated pads in the top right corner of the board images are for this purpose. Just solder there a small SMD capacitor (10-50pF, in a 0603 or package I think, or a 0805) and the sensitivity should decrease. on Step 2. on Step 2. TTP223 Capacitive Touch Sensor is a very useful addition for projects or applications where a conventional mechanical button or switch is not an ideal choice.

Drone on Running Way More LED Strips On A Raspberry Pi With DMA 2 years ago, Reading the datasheet, the sensitivity can be decreased bya) reduce the size of the sensor (which you cannot do)b) increase the distance (for instance put some plastic above the contact)c) add a capacitor between the sensor and ground.If you can't do solution b, then I suggest you to add a capacitor. One of them (red, most likely) will have a lower forward voltage than, say, a blue, so the blue will never turn on. Speakers Power. The forward voltage may be too high, and a typical "9V" alkaline battery only puts out 7.2V. I've tried to power on my Attiny85 with neopixel ring but the neopixels just light orange or white instead of doing the rainbow effect? There are different kinds of user input methods used in the embedded and digital electronics.
