Instead of having to \u003cem\u003eturn knobs \u003c\/em\u003ewith your \u003cem\u003eHANDS \u003c\/em\u003elike an \u003cem\u003eANIMAL \u003c\/em\u003ethe DS3502 I2C Digital Potentiometer allows you to let your microcontroller adjust the resistance for you!\u003c\/p\u003e\n\u003cp\u003eNow you can free your hands to spin your fidget spinner or or eat a slice of pizza while you're on the phone. Talking over an I2C bus, your Arduino, CircuitPython board,  or Python powered computer can talk to the DS3502 and tell it to vary its resistance at your beck and call.\u003c\/p\u003e\n\u003cp\u003eWorking with the DS3502 is easy as an I2C controllable pie. Adafruit have put it on a breakout PCB with the required support circuitry and \u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSparkFun qwiic\u003c\/a\u003e compatible \u003ca target=\"_blank\" rel=\"noopener noreferrer\" href=\"https:\/\/learn.adafruit.com\/introducing-adafruit-stemma-qt\"\u003e\u003cstrong\u003eSTEMMA QT\u003c\/strong\u003e\u003c\/a\u003e connectors to allow you to use it with other similarly equipped boards \u003cstrong\u003ewithout needing to solder.\u003c\/strong\u003e This handy little helper can work with 3.3V or 5V micros, so it's ready to get to work with a range of development boards. The DS3502 is a simple chip that does one thing well and so it's very easy to work with. Wire it up and set the value for the wiper, thats it. \u003ca href=\"http:\/\/learn.adafruit.com\/ds3502-i2c-potentiometer\/\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eTo make things \u003cem\u003eeven easier\u003c\/em\u003e Adafruit have gone and written Arduino and CircuitPython\/Python 3 drivers to simplify interfacing with your new knob-replacing friend.\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\"OK, this thing sounds great. Give me some details\" you say. OK then, here you go: The wiper value is a 7-bit number meaning there are \u003cstrong\u003e128\u003c\/strong\u003e possible levels of resistance to choose, from \u003cstrong\u003e0-10K ohms\u003c\/strong\u003e. You can even set a default value that will be set on power up. The analog voltage controlled can be from \u003cstrong\u003e4.5-15.5V.\u003c\/strong\u003e Additionally you can use the address jumpers or pins to set the I2C address to one of four values, allowing you to have four DS3502s on the same I2C bus.\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/ds3502-i2c-potentiometer\/\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eDiagrams, libraries, code examples, datasheets, and more are all in the learning tutorial\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eProduct Dimensions: 25.4mm x 17.7mm x 4.6mm \/ 1.0\" x 0.7\" x 0.2\"\u003c\/li\u003e\n\u003cli\u003eProduct Weight: 1.6g \/ 0.1oz\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":29445410947155,"sku":"ADA4286","price":10.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/4286-03.jpg?v=1565360187","url":"https:\/\/shop.pimoroni.com\/en-nz\/products\/adafruit-ds3502-i2c-digital-10k-potentiometer-breakout-stemma-qt-qwiic","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
