Capacitive Touch Sensor for Arduino

This is an amazing touch sensor designed specifically for Arduino. It features a toggle output type - simply touch to turn on and touch again to turn off. It comes with an onboard TTP223 touch capacitive sensor IC and an on - board level status indicator to easily show its working state. With a wide working voltage range from 2.0V to 5.5V, it's very flexible to use. The PCB board has a compact size of 29mm x 16mm, making it easy to integrate into your projects.

Using this touch sensor for your Arduino project is a breeze. First, connect the sensor to your Arduino board following the basic wiring principles. Make sure the power supply is within the 2.0V - 5.5V range to avoid any damage. Once connected, you can start programming the Arduino to respond to the touch events. When you touch the sensor, it will toggle its output state. Regarding maintenance, keep the sensor clean and dry. Avoid exposing it to extreme temperatures or humidity. If there are any issues, check the connections first to ensure they are secure. That's all you need to know to make the most of this great touch sensor.
