There is a common misconception in the Arduino scene, that I/O pins are somehow (safely) current limited and need no resistors with LEDs, but this is not actually the case. It would be good if at ...

James began blogging about technology two decades ago while living in Japan and joined MakeUseOf as a writer in 2010, before quickly ascending the ranks to webmaster, Reviews Editor, and CTO. He ...

Discover how you can build a professional digital multimeter using Arduino that measures up to 24V DC voltage, checks resistance, conducts diode testing, and performs continuity tests. This ...

Arduino DS3231 Real Time Clock (RTC) with Temperature Monitor Introduction: The DS3231 is a low-cost, extremely accurate I²C real-time clock (RTC) with an integrated temperature-compensated crystal ...

The two SCD41 sensors we want to connect have an I2C address of 0x62, which cannot be changed. Therefore, to communicate with both sensors from the micro controller, we will use a separate I2C bus for ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

I created an Arduino based load shedding demonstration project, using DC supply and low voltages. Devices used : Arduino Uno R3 5V relay module I2C LCD 9V dc motors (loads) Resistors 1 ohm, 220 ohm, ...
