Metal touch sensor bounce1/21/2024 ![]() Now, touch the base electrode of the transistor and the LED attached to pin 13 on the SunFounder Uno board will light up. Step 4: Upload the sketch to SunFounder Uno Step 2: Program (Please refer to the example code in LEARN -> Get Tutorial on our website) When the metal touch sensor detects touch signals, the LED will be on. With the LED attached to pin 13 of Uno, connect pin D0 of the sensor to D7 of the Uno board. These electromagnetic wave signals collected by human body are amplified by the transistor and processed by the comparator on the module to output steady signals. In this experiment, touch the base electrode of a transistor with fingers to make it conduct electricity, for human body itself is a kind of conductor and an antenna that can receive electromagnetic waves in the air. It has a high-frequency transistor which can conduct electricity when receiving electromagnetic signals. Cutting-edge testing tools and quality control teams were employed on all goods in stock. ![]() ![]() It possesses cutting-edge production and processing technologies and a dependable supply network. A metal touch sensor is a type of switch that only operates when it’s touched by a charged body. The metal mesh touch sensor is the most dependable and stable one available. The sensing surface of a capacitive sensor is formed by two concentrically shaped metal electrodes of an unwound capacitor. ![]()
