{"version":"1.0","description":"Let\u2019s read data sheet (PDF ). It says resistance changes 1K - 100K (roughly linear). I used 10K ohm resistor to measure as follows. In theory, if you touch the censor, resistor values decreases and the voltage increases. So simply read the voltage using A0. // Force-Sensitive Resistor // #include <s\u2026","blog_title":"higepon blog","provider_url":"https://hatena.blog","height":"190","url":"https://higepon.hatenablog.com/entry/20140927/1411823464","author_name":"higepon","author_url":"https://blog.hatena.ne.jp/higepon/","published":"2014-09-27 22:11:04","categories":["spark core"],"type":"rich","width":"100%","provider_name":"Hatena Blog","image_url":"https://cdn-ak.f.st-hatena.com/images/fotolife/h/higepon/20140927/20140927060551.jpg","html":"<iframe src=\"https://hatenablog-parts.com/embed?url=https%3A%2F%2Fhigepon.hatenablog.com%2Fentry%2F20140927%2F1411823464\" title=\" 12.Force-Sensitive Resistor - Spark Core - higepon blog\" class=\"embed-card embed-blogcard\" scrolling=\"no\" frameborder=\"0\" style=\"display: block; width: 100%; height: 190px; max-width: 500px; margin: 10px 0px;\"></iframe>","title":" 12.Force-Sensitive Resistor - Spark Core","blog_url":"https://higepon.hatenablog.com/"}
