For connection I used 3 potentiometers pinned to A0, A1 and A2. And the processing code: // This example code is in the public domain. import processing.serial.*; float redValue = 0; // red value float greenValue = 0; // green value float blueValue = 0; // blue value float xPos=0; float yPos=0; […]
The speaker in general can consists from the following parts: – a coil (thread,wire …) – a neodymium magnet – a vibrant material (plastic, fabric, paper …) I wanted to design home made coil. By researching interesting ideas and designs I run into optimize coil design made by Plusea. My design approach for workshop was […]
I took apart a small speaker. It is made of a magnet ring, a metallic part (in the middle of the ring), a plastic holder, plastic membrane and a copper wire as a coil. Copper wire (profile: 0,1 mm) is 140 cm long and at least 50 times curled to form the coil. The coil […]
Pressure sensor is made like a bend sensor with a conductive thread, velostat, conductive fabric and non-conductive material. Structure of pressure sensor (click for bigger picture) Parts of the sensor: – Conductive thread : to connect threads in the circuit – Non-conductive material (neoprene) : to give the sensor structure – Velostat : […]
digitalWrite The digital pins have only two modes – ON (1) or OFF (0). We use the constants HIGH (on) and LOW (off) since this makes it easier to read code. Digital pin always gives the output power of 5V when HIGH and 0V when LOW. The pin need to be configured with pinMode( ). […]
