Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the answer appears ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Connect the VEML6040 sensor to your Arduino board's standard I2C bus. Check the pinout of your Arduino board to find the correct pins. Important: without additional level shifting the VEML6040 is not ...

Abstract: The ocean covers nearly two-thirds of the surface on the Earth, and there has been great interest in developing underwater wireless sensor networks (UWSNs) to help us explore the ocean realm ...

The MAX471 is an older current sensor which can handle up to 50 Watt, with a maximum of 25 Volts or a current of 3 Amperes. It is officially not supported any more however there are still many for ...
