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 ...
WiFi and Bluetooth LE can now be used simultaneously on Arduino boards with NINA-W102 (ESP32) module
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, ...
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 ...
An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention. The “automatic toll gate system project” demonstrates how simple sensors and ...
Temperature sensing is one of the most commonly specified attributes for monitoring and control of critical processes. So many physical and chemical processes rely on close control of temperature that ...
I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
The wearable sensor market is growing at an annual compound rate of 17.8%. However, sensors have challenges, particularly in terms of miniaturization and power consumption. Several key parameters are ...
