Most people have seen inductive charging in a rechargeable electric toothbrush: you may have noticed that you recharge it by placing it into the holder, but there's no direct plug.

Then, each individual LED has a smaller coil on the back. When the two couple, power is transferred from the coil to LED and it lights up. You can have a large number of LEDs, all in different 3D space above or below the coil. You can also have them in different orientations, although you will get the best efficiency\/power transfer when the two coils line up. You can also have the LEDs slightly outside the main ring, but, again, they'll not light up as bright as if they're right in the centre.\u003c\/p\u003e\n\u003cp\u003eView our full range of Adafruit products here.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/h55V3rZYaj0?si=cpvQuzCRPtrTv4vl\u0026amp;start=187\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSingle miniature LED inductor: 4.8mm height, 4.5mm diameter\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eApproximate working distance when used with small ring, LED in the centre, aligned co-axially: 8cm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eApproximate working distance when used with large ring, LED in the centre, aligned co-axially: 10cm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Small Inductive Wireless LEDs - 10 Pack - Red\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSmall or Large Inductive Coil Kit sold separately\u003c\/strong\u003e\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43643617869885,"sku":"uih1789691261513","price":6.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/9716\/8957\/files\/small-inductive-wireless-leds---10-pack---red_1.jpg?v=1789691266"},{"product_id":"self-test-cable-for-home-automation-hat-discontinued","title":"Self-Test Cable for Home Automation HAT [Discontinued]","description":"\u003cp\u003eThis self-test cable works with the Sequent Home Automation 8-layer stackable HAT, allowing you to test groups of three inputs and outputs on the HAT.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThree-connector cable for self-testing the Sequent Home Automation HAT\u003c\/li\u003e\n\u003cli\u003eSelf-test groups of 3 inputs and outputs\u003c\/li\u003e\n\u003cli\u003eCommand-line software for each test\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow to Use\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eTest the GPIO and Opto-Inputs 1-4:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInsert the cable on the left side of the card, as shown in the picture below, and run the self-test command\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0176\/3274\/files\/test1s2_1.jpg?v=1645193597\u0026amp;width=700\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTest the analog inputs and outputs:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eInsert the cable on the bottom side of the card, as shown in the following picture, and run the self-test command.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0176\/3274\/files\/test2s2_1.jpg?v=1645193597\u0026amp;width=700\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTest the open-drain outputs and opto-inputs 5-8:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eInsert the cable on the right side of the card, as shown in the following picture, and run the self-test command.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0176\/3274\/files\/test3s2_1.jpg?v=1645193597\u0026amp;width=700\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTesting the relays\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWithout the loopback cable, run the command relay_test.

Meaningful results can be available within 1 ms in typical cases (i.e. when not trying to measure subtle differences in low-reflectance scenarios), allowing up to 1 kHz sampling of all sensors. If lower-frequency sampling is sufficient, you can achieve substantial power savings by turning off the LEDs.

This change in reflectivity can be due to a colour change at a fixed distance, such as when sensing a black line on a white background, as well as due to a change in the distance to or presence of an object in front of the sensor.

A Python script is available which makes using this mode very simple: you just run \u003ccode\u003epython pyboard.py script_to_run.py\u003c\/code\u003e and this will execute \u003ccode\u003escript_to_run.py\u003c\/code\u003e on the pyboard, returning any output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrom file:\u003c\/strong\u003e The pyboard has a small, built-in filesystem, which lives in part of the flash memory of the microcontroller. It also has an SD card slot if you want to extend the available storage. When you connect the pyboard to your PC, it appears as a USB flash storage device and you can access (mount) the internal filesystem and the SD card this way. If you copy a Python script to the filesystem and call it \u003ccode\u003emain.py\u003c\/code\u003e then the board will execute this script when it starts up. This way you can run scripts without being connected to a PC.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHardware features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSTM32F411RE microcontroller\u003c\/li\u003e\n\u003cli\u003e96 MHz Cortex M4 CPU with hardware floating point\u003c\/li\u003e\n\u003cli\u003e512KiB flash ROM and 128KiB RAM\u003c\/li\u003e\n\u003cli\u003eMicro USB connector for power and serial communication\u003c\/li\u003e\n\u003cli\u003eMicro SD card slot, supporting standard and high capacity SD cards\u003c\/li\u003e\n\u003cli\u003e24 GPIO on left and right edges and 5 GPIO on the bottom row, plus LED and switch GPIO available on the bottom row\u003c\/li\u003e\n\u003cli\u003e1x 12-bit analog to digital converter, available on 16 pins, 4 with analog ground shielding\u003c\/li\u003e\n\u003cli\u003e4 LEDs (red, green, yellow, and blue)\u003c\/li\u003e\n\u003cli\u003e1 reset and 1 user switch\u003c\/li\u003e\n\u003cli\u003eOn-board 3.3V LDO voltage regulator, capable of supplying up to 250mA, input voltage range 3.6V to 16V\u003c\/li\u003e\n\u003cli\u003eDFU bootloader in ROM for easy upgrading of firmware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe two mounting tabs on the pyboard have perforations so that you can snap them off cleanly if needed.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cp\u003eThere is an active MicroPython community, and you can join in at:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMicroPython Forum\u003c\/li\u003e\n\u003cli\u003eMicroPython on GitHub\u003c\/li\u003e\n\u003cli\u003ethe IRC channel\u003c\/li\u003e\n\u003cli\u003eTwitter\u003c\/li\u003e\n\u003cli\u003eFacebook\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIf you have other inquiries, their contact email is \u003cstrong\u003econtact@micropython.org\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e\n\u003cli\u003eFeature Table\u003c\/li\u003e\n\u003cli\u003epyboard Schematics\u003c\/li\u003e\n\u003cli\u003ePinout Diagram\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43643671412797,"sku":"erg1789691971939","price":30.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/9716\/8957\/files\/micropython-pyboard-lite-v10---stm32f411-discontinued_1.jpg?v=1789691975"},{"product_id":"esp32-s2-lcd-wifi-development-board-pico-format-discontinued","title":"ESP32-S2 LCD WiFi Development Board (Pico Format) [Discontinued]","description":"\u003cp\u003eThis is a compact WiFi LCD development board from Waveshare based on the ESP32-S2 with a pinout that supports most HATs designed for the Raspberry Pi Pico!\u003c\/p\u003e\n\u003cp\u003eThe board offers a 160x80 IPS colour 0.96\" LCD, onboard 3.7V lithium battery charge\/discharge header, numerous peripheral interfaces, integrated low-power Wi-Fi System-on-Chip (SoC), USB-C connectivity and mass memory.
