??<strong>Features:</strong><br /> Easy to start - The Shieldbot is plug and play and can be running out of the box in minutes.<br /> Expandable for imagination - solderless grove expansion ports enable easy attachment of more sensors and actuators£¬ and shield headers allow the use of additional Arduino shields.<br /> Open source - Its designed to be hacked£¬ adapted and transformed into whatever you want it to be!<br /> Arduino Based - the Shieldbot is an Arduino shield£¬ so the extensive Arduino community and shield ecosystem can be used for endless expansion!<br /> <br /> <strong>Specifications:</strong><br /> 5 IR reflectance sensors for line and edge following<br /> Two durable 160:1 micro metal gearmotors<br /> 6 Grove expansion ports<br /> Stackable shield headers<br /> Working voltage: 7.4V battery or 11V-15VDC<br /> Working current: £¼1.5A<br /> Li-ion rechargeable battery: 900mAh£¬ 7.2V<br /> Max. speed of motor: 160RPM<br /> Max. torque of motor: 1Kgf.cm<br /> <br /> Interface Function:<br /> <br /> Power Switch: When ShieldBot is off£¬ The shield bot can not run. But you can use the USB Charge Port to charge for battery.<br /> USB Charge Port: USB mini-B£¬ used for charging for battery.<br /> Grove Ports: Grove ports access pins D0£¬ D1£¬ D2£¬ D3£¬ D4£¬ D5£¬ A4£¬ A5. Can connect Grove modules to these Grove ports.<br /> IR Line Finder Potentiometer: Used for adjusting the Line Finders Sensitivity. Clockwise adjustment£¬ the Sensitivity increases; Counterclockwise adjustment£¬ the Sensitivity decreases.<br /> IR Line Finders: S1 to S5. Blue if non reflective surface is detected (ex Black tape line)<br /> Enable Switch: Turn switch towards "ON" to connect line finders to I/O pins(Occupied pins are A0£¬ A1£¬ A2£¬ A3£¬ D4) of Arduino. The LineFollowingSimple demo in library is used line finders output signal to control Shield Bot run. If switch is toward "OFF"£¬ Seeeduino/Arduino cannot control Shield Bot through line finders output signal.<br /> Arduino Shield Expansion Headers: Shield Bot can truly stack other shields.<br /> <br /> Note: 1. If S5 is enabled you can&#39;t use grove ports j14 and j13.<br /> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 2. You may only use ONE of the arduino&#39;s serial line£¬ uart grove port or j11 as they all share the D1/TX line.<br /> &nbsp;
