This is a how to make a useful photoreflector for Arduino.

Photoreflector is a sensor that is often use for line tracer.

Step 1: Tools

  • Soldering iron
  • Solder (1.0mm)
  • Nipper

Step 2: Materials

  • Photoreflector LBR-127HLD, 50JPY
  • 180 Registor (180R), about 10JPY
  • 10K Registor (10K) about 10JPY

total price 70JPY.

In Japan, same photoreflector is about 550JPY!? ( see POLOLU-2458 )

Step 3: Hold a Photoreflector

Step 4: Fold 1 and 4 of the Photoreflector

Step 5: Fold 2 Against 3 of the Photoreflector

Step 6: Fold 2 of the Photoreflector for Closing Contact 4 of It

Step 7: Sold 2 and 4 of the Photoreflector

Step 8: Cut 2 of the Photoreflector at Root.

Step 9: Fixed 180R Near Root of 1 of the Photoreflector

Step 10: Sold 180R and 1 of the Photoreflector

Step 11: Cut Solded a Wire of 180R and a 1 of Photoreflector

Step 12: Fold a 10K Wire Near Root of 4 of the Photoreflector

Step 13: Sold a 10K Wire and 4 of the Photoreflector

Step 14: Cut Only a 10K Wire

Step 15: Earn 4 of the Photoreflector

Step 16: Fold a 10K Wire and 1 of the Photoreflector

Step 17: Sold a 10K Wire and a 180R Wire

Step 18: Cut Only 10K Wire

Step 19: Cut Too Much Wire of 180R

Step 20: Finished!
