  There’s some info apparently missing at the end of the first paragraph on the page. The last sentence is truncated. It reads, “In order to best protect your pi 3….”

  What are we supposed to do to best protect our pi 3?

    thx for your notice.
    In order to best protect your pi 3, you’better to connect the component with 3.3V GPIO (Note: For some sample projects, you need to connect 5V GPIO, pls follow our sample project to test your component.)

  Why did my kit contain 200ohm resistors instead of 220ohm that the projects call for?

    We have changed the package of the Resistors.

  Hi, do you have the datasheet for the photo resistor or its code? Thanks

    Do you mean you need resistor color code: https://osoyoo.com/2014/12/08/how-to-read-resistor-color-code/

      No, I mean the photoresistor used in this project

      https://osoyoo.com/2016/12/16/raspberrypi-photoresistor/

      I would like to convert the readings to actual lux.

      Thanks

  Raspberry Pi/Arduino 8-チャンネル TTLロジックレベル変換器の使い方を教えていただけないでしょうか？
  サンプルプロジェクトも無く行き詰っています。

  ・これは双方向ではなく、一方向(A to B)の変換のみであっていますでしょうか？

  ・変換機には、VCCAが2ピン、VCCBが2ピン、GNDが4ピン存在します。
  　これは全て接続する必要がありますか？

    sorry, i don’t know how to write Japanese. I use English to reply your question.
    1)The TTL Logic Level Converter showed in this kit is bi-directional. That means you can convert both from 3.3V signal to 5V signal and reversely from 5v to 3.3V
    2)please connect VCCA to 3.3V and VCCB to 5V, all A pins connect 3.3V devices and B pins to 5V devices.

    Hope this is clear
    日本語で説明します：
    1)このキットでのTTLロジックレベル変換器は双方向の物です。3.3vから5vへ変更できるし、5vから3.3vへ変更も大丈夫です。
    2)VCCAと3.3V、VCCBと5Vを接続してください。すべてのAピンと3.3V設備を接続し、すべてのBピンと5V設備を接続してくださいませ。

  丁寧なご回答ありがとうございました。

  説明のとおり接続したところ、3.3Vから5Vへ変換できることが確認できました。

  勉強になりました。
