[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

Reads the analog temperature sensor every 100 ms. Converts analog value to temperature (°C). Stores it in a shared variable currentTemp protected by a mutex. alarmTask Checks the current temperature ...

下記の記事の続きです。前回の記事では、この取り組みの背景と温度及び湿度の計測機能の実装について書きました。この記事では、wifiモジュールによるIoTデバイス化と、MH-Z14Aによる二酸化炭素濃度計測機能の実装を行います。 Arduinoは単体で ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...
