電子工作をしていると，湿度・温度モジュールDHT11や，液晶ディスプレイ I2CLCD1602モジュールなど．電源に 5V が必要となる場面が多々ある． いくつかの 5V 電源を Raspberry Pi や Arduino から給電すると，1つのピンに対して，過電流（1つのピンに流れても良い ...

With the local oscillator working entirely, the next step is checking to see if the signal goes through the bandpass filters properly. To do this, I needed to program the arduino to select the ...

This document is aimed at the Arduino developers, radio experimenters, hobbyists and anyone interested in building a receiver based on the Si473X IC family from Silicon Labs. This project is about an ...

Powering an Arduino has a little magic to it. It wasn’t obvious to me when I first started working with them, but Arduinos have on-board regulation. Taking advantage of this allows for longer power ...

人気のシングルボードコンピュータ（SBC）であるRasberry Piと同様に有名なSBCであるArduinoを紹介します。 Arduinoは2005年イタリアの大学教授Massimo Banzi氏らによって開発された、コンピュータ初心者向けの「電子工作用マイコンボード」です。 下記特徴により ...

If your introduction to digital electronics came more years ago than you’d care to mention, the chances are you did so with 5V TTL logic. Above 2V but usually pretty close to 5V is a logic 1, below ...

The sensor has 3 wires RED, YELLOW, and BLACK as shown in the figure below. The red wire is used for supply voltage which ranges from 5V to 18V and the black wire is ...
