IR Infrared Obstacle Avoidance Sensor Module. All the sensor setup requires is a medium to high value resistor and a piece of wire and a small (to large) piece of aluminum foil on the end. Computer input devices are indifferent to human contact as there is no reaction from software in the event of making, maintaining or breaking physical contact like touches or releases.Thus, touch sensing input devices offers numerous possibilities for novel interaction techniques. However, there are 4 wires from the Arduino to the EasyDriver, and one from the hall effect sensor (though it seems that a simple pushbutton switch would work as well). When the value is sufficiently high, or low, tell the stepper to step the required number of steps. The circuit is very simple and easy to build and can be built on the breadboard. I am currently designing a Triac Interface circuit and was wondering what the performance of the TTP223 is when it's connected to the "live" 240V line and hence following the supply up and down by +/-330V with resepct to ground.

Find this and other Arduino tutorials on ArduinoGetStarted.com. It consumes very low power and the operating voltage is only between 2.0V~5.5V. The response time max about 60mS at fast mode, 220mS at low power mode @VDD=3V. Sensitivity can adjust by the capacitance(0~50pF) outside. A touch sensor is a touch-sensitive module which has 3 input/output pins. To interface the relay, it is important to have a fair idea about the relay’s pin description. The complete circuit diagram used in this project is shown below. You'll often find temperature and humidity sensors bundled within the same breakout board. The module is also widely used as an input device, which can be interfaced with a microcontroller (e.g Arduino). Step 2a: Making the touch detection circuit To start, take your wire and strip it down completely (remove all of the insulation) and connect it to pin 2 of the Arduino. Touch sensor interfacing with Arduino A touch sensor is an electronic sensor that is used to detect the touch when it is touched it acts as a switch. Basically the arduino measures how much time the capacitor (i.e the touch sensor) takes to charge, giving it an estimate of the capacitance. Can replace traditional Dimmer Switches like slide switch or rotary type switch for bulbs. However, to detect the touch accurately, a debounce delay is used. TTP223B IC based digital capacitive sensors are very affordable and gives good response when we touch it, this sensor breakout can be easily interfaced with any kind of microcontrollers, and contains only three terminals for external interface.
