Check technical details and commands against the product version and manufacturer documentation before use.<br /> <br /> == Summary ==<br /> Technical overview of the AlphaBot2-Ar kit for Arduino, covering hardware components, sensors, control programs, and calibration.<br /> <br /> == Related products at JW Tech ==<br /> * [https://shop.jw-tech.eu/p/WSAL12910 WSAL12910 – AlphaBot2 robot building kit for Arduino]<br /> * [https://shop.jw-tech.eu/p/WSAL12911 WSAL12911 – AlphaBot2 robot building kit for Arduino (no Arduino controller)]<br /> <br /> == Technical overview ==<br /> * The kit consists of the AlphaBot2-Base chassis and the AlphaBot2-Ar adapter board. Assembly is snap-together without soldering or wiring.<br /> * The chassis includes a TB6612FNG motor driver, two N20 DC motors with 1:30 gear reduction (6 V/600 RPM), rubber wheels (42 mm diameter, 19 mm width), and a battery holder for 14500 cells.<br /> * The adapter board provides an Arduino socket, an Xbee connector for Bluetooth modules, an IR receiver, a PC8574 I/O expander, a TLC1543 10-bit ADC, a 0.96-inch SSD1306 OLED (128x64), and a joystick.<br /> * If wheel direction is wrong, adjust pin settings AIN1/AIN2 (left wheel) and BIN1/BIN2 (right wheel).<br /> * Infrared remote uses numeric keys: “2” forward, “8” backward, “4” left, “6” right, “5” stop; “+”/“-” adjust speed, “EQ” resets it.<br /> * Ultrasonic ranging program requires the serial monitor baud rate set to 115200.<br /> * Infrared line tracking requires calibration: hold the robot on a black line, swing it side-to-side so max/min thresholds are detected.<br /> * OLED example programs demonstrate character display and basic drawing; the corresponding libraries must be installed in the Arduino IDE folder and the IDE restarted.<br /> <br /> == Notes and version constraints ==<br /> * Infrared remote key encoding may vary by model; adjust the program as needed.<br /> * Ultrasonic distance readings can be inaccurate when obstacles are not directly in front but at an angle.<br /> * Line-tracking calibration directly affects tracking performance; recalibrate if behavior is incorrect.<br /> * There is no smart charging system; the battery is fully charged when the charge LED turns off.<br /> * Bluetooth control requires removing the module before flashing the program, then reinserting it.<br /> <br /> == Source and revision record ==<br /> * [https://www.waveshare.com/wiki/AlphaBot2-Ar AlphaBot2-Ar - Waveshare Wiki]<br /> * Source revision: 81562<br /> * Captured: 2026-08-30T03:35:04+00:00<br /> * SHA-256: &lt;code&gt;31356f8fd9f6ef0d72859adcd66a3e20c03e84b64fbedfbccd29f134d7f4cb6a&lt;/code&gt;</div>
