This product is EOL. Description TRACE unit is mainly consist of 4 sets of IR, 1x infrared emitting and 1x infrared receiver for each set. The infrared LEDs should be placed toward s and close to the ground where having black tracing lines and white background (or vice versa) layouts. The IR transmitter keep emitting, at the mean time infrared ray would be absorbed by different color of objects. Black can absorb more ray than other color, so the infrared receiver (infrared sensitive phototransistor) would receive less which makes the resistance value of the phototransistor would vary with different object color. Then we assign an AD convertor tp capture the data. This Unit communicates with the M5Core via GROVE PORTA I2C (0x5A). Product Features operation range: The reflecting surface is less than 11mm from the photoelectric surface Program Platform: Arduino, UIFlow (Blockly, Python) Two Lego-compatible holes Include 1x TRACE Unit Applications Self-tracing robot Specification Resources Parameter Net weight 32g Gross weight 34g Product Size 70*16*18mm Package Size 200*100*10mm Show more
