Line Follower Array 八路矩陣循線尋跡模組 SparkFun原廠

商品說明

SparkFun Line Follower Array 是一個長板，由八個紅外傳感器組成，已經配置為讀取數字位！我們設計了SparkFun線追踪器陣列，以便在淺色背景上遵循約3/4英寸寬（或更小）（噴漆或電膠帶）的深色線。每個陣列具有可見的LED，當板被連接（適當）時向上指示，以便您可以看到機器人看到的內容，板上的亮度控制以及用於讀取和電源控制的I ² C接口。在SparkFun中，RedBot Shadow Chassis被用作測試平台，但實際上它被設計為幾乎任何機器人的附件。

線跟隨器通過對後續線使用8位讀取反射率或讀取暗/光圖案進行功能，並且可以從大約1/4到¾英寸處看到。紅外亮度控制和指示燈可以使用板載電位器進行調節，並能夠顯示紅外LED的強度。照明可以通過軟件打開和關閉，以節省電量，或者始終保持更快的讀數。SparkFun線路跟隨器陣列需要5V的電源，電源電流範圍為25-185mA，禁止選通，16-160mA使能。另外，我們已經為線路跟隨器添加了六個安裝孔，其中兩個內部孔設計為適合我們的陰影底盤，而另外四個是通用的。

注意：如您所知，我們的太陽能發出相當多的紅外線，使得SparkFun Line Follower Array在陽光直射下的效率更低。相應規劃您的項目！

SparkFun Line Follower Array

The SparkFun Line Follower Array is a long board consisting of eight IR sensors that have been configured to read as digital bits! We have designed the SparkFun Line Follower Arrays to follow a dark line of about ¾ inch width or smaller (spray paint or electrical tape) on a light background. Each array features visible LEDs that point upward when the board is attached (properly) so you can see what the robot sees, brightness control right on the board, and an I²C interface for reading and power control. Here at SparkFun, the RedBot Shadow Chassis was used as a test platform but really this was designed as an add-on for almost any bot.

Here at SparkFun, the RedBot Shadow Chassis was used as a test platform but really this was designed as an add-on for almost any bot.

The line follower functions by taking an 8-bit reading of reflectance for use with following lines or reading dark/light patterns and can see from about 1/4 to 3/4 inches away. The IR brightness control and indicator can be adjusted with the on-board potentiometer and is capable of showing you the strength of the IR LEDs. Illumination can be turned on and off with software to conserve power, or left on all the time for faster readings. The SparkFun Line Follower Array requires 5V of power with a supply current range of 25-185mA with strobing disabled and 16-160mA with it enabled. Additionally we have added six mounting holes to the line follower with the two inner holes designed to fit our Shadow Chassis while the other four are general purpose.

Note: As you know our Sun emits quite a bit of infrared light, making the SparkFun Line Follower Array much less effective in direct sunlight. Plan your projects accordingly!
