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
i dont get it, you make a photoreflector out of.... a photoreflector. Or am I missing something. Entire photoreflector board is 90 euro cts at aliexpress:

Resistor.
Not registor.

Looks great! Thank you.
But in Step 2: Materials
Register - it's a mistake, a resistor - right

I fixed, thanks!

You didn't
currently it is listed (twice) as a "Registor"
BTW, I would also suggesto to explain how the photoreflector becomes actually more useful with those two resistors.

Here in the Philippines it would cost 15 PHP or about 40JPY
I use a 220 Resistor instead of using a 180 for a sensitive/ longer range detection
or a 1k Resistor for a close range detection

In Japan, this is about 70JPN.
A manufactured one is POLOLU-2458 ( https://www.pololu.com/product/2458 ). It's 550JPY.

This looks so great! Have you noticed any difference from this and a commercially manufactured one? What's the price difference?
