「Arduino」の「シリアル通信」についてまとめました。 「Arduino」は、他のデバイスと通信するために、どのボードにも最低1つの「シリアル通信」を行うためのポートが用意されています。通常、「TXピン」(1ピン)と「RXピン」(0ピン)が使われます。 「Arduino ...

For the challenge, I wanted to send data from my computer's real serial port (RS232 9-pin connector). For that, I created an adaptor circuit because the voltages on a computer serial port are ...

We’ll admit it, we’re all spoiled. A few bucks can now buy a computer that would have been the envy of everyone back in the late 1970s or early 1980s. So it’s no surprise that [krallja] was able to ...

Arduino Unoでは、PA4、PA5をI2Cに使用するので、I2C通信を使う場合は、アナログ入力としてはこれらを使用できません。 shieldで良く使われるSPI。 ICSP(In Circuit Serial Programming) Pinは、PD11 - PD13と物理的に繋がっており、SPI通信に使われています。 SPIを使用する時は ...

Outputting data from a microcontroller over a serial port is convenient and easy, but formatting, visualizing, and analyzing the data can be tedious and frustrating. [Alex Spataru] knows this all too ...

This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable environmental monitoring system. It measures ambient ...

I like to visualize things, so I decided to prepare this simple tutorial to help you better understand how to visualize data using Arduino. This tutorial assumes that you have some basic electronics ...
