    5.0 out of 5 stars Good fun to build

    A. · 20 July 2024

    This kit is great but some knowledge of electronics would be required as there are no instructions and you have to follow the legend on the circuit board to know where the components go and care would be required for the polarised components. The kit functioned excellent and although it’s not exact the distance measured is with in a few Centimeters.

    5.0 out of 5 stars I worked when completed

    D.J. · 28 April 2023

    Easy to assemble, I want a project I could do to with the free time I had and it was fun to build, although it doesn't like angled walls much and you have to allow around 1" to 2" at the front of the device to get a good measurement, its a good project to complete.

    Manque instruction de montage mais fonctionne bien quand même

    J.S. · 1 September 2023

    Malgres le manque d'instructions de montage, on peut lire sur le circuit imprimer ou poser les pièces et regarder les photos du produit. J'ai réussi à le monter avec mon fils de 9 ans en 1h et ça marche super bien. Il est ravie.

    Fehledes Bauteil und keine Beschreibung

    Der 2. Ultraschallsensor fehlt.Zusätzlich gibt es keine Aufbauanleitung.

    久々に半田付けした、楽しい！

    コ. · 26 April 2024

    The media could not be loaded. 近距離（０～１M）あたりなら、思ったより実用的だなと思いました。　液体の水面計として使えるかなとテストしたところ、使えそう。　興味心でラズパイを持っていますが、ちっとも勉強が進まないし、単純な距離計としたら、この手のモジュールのが便利かなと思いました。　星減点要素ですが、「説明書が紙切れ１枚すらありません」「抵抗の帯の色が判別できない（部品テスターで判別）」「部品リストがないのに、中途半端に部品が余る！」　　プログラムできる８ビットマイコンICなんてあるんですね～。ネットで型番調べたら・・・ラズパイよりもディープな世界でしたので私には書き込みは無理っぽいかな。　トランジスター４個のうち１個は、ブザー用です。ブザーがアクティブなのかパッシブなのか、私には判別できませんが、リレーモジュールに繋げて他の制御にも使えそうです。　残りの３つのトランジスターは７セグに向かってます。このマイコンICの出力電流が小さいと書いてあったので、７セグの各桁の電源用みたいですね。　とりま、私は４０代で目のピント機能が弱まっていますが、中学生時代以来に半田ごてを使用して電子工作をしまして、無事に一発で正常稼働しました。　キットとしては問題ない製品だと思います。
