After compiling and uploading a sketch, a digitalRead of a pin or an interrupt on a pin will do what it is supposed to. After a deepSleep(), the same event will reset the ESP8266. This example was ...

Seeeduino XIAOのdigitalReadを高速化したいので、レジスタから読み出すように変更すると3倍ほど早くなった。シングルサイクルIOを使用すると5倍ほどはやくなった。 Arduino DIO高速化に関する記事は探すといっぱい出てきて正規？のArduinoではdigitalReadの代わりにPINx ...

①Arduinoの5VピンとGNDピンをブレッドボードに接続 ② 赤のLED2個と緑のLEDを1個をブレッドボードに差し込む ③ LEDそれぞれの短い方の足に220Ωの抵抗器を接続 ④ 抵抗器の反対側をGNDに接続 ⑤ 緑のLEDの長い方の足をArduinoの3番ピンに接続 ⑥ 赤のLEDの長い方の足 ...

Despite a wealth of tutorials for setting up and writing code for the ESP8266 WiFi module, there has not been much of anything on programming this cheap wireless module with the Arduino IDE. Finally, ...

Sometimes the conveniences of using an Arduino board start to conflict with the performance that you expect, at least from a strict engineering point of view. When you develop with the Arduino ...

A Microcontroller uses many different protocols to communicate with various sensors and modules. There are many different types of communication protocols for wireless and wired communication, and the ...
