but we can also utilize this Arduino based speed sensor in scientific experiments to study motion, acceleration, or friction by measuring the speed of different objects in a controlled environments.

Using the Arduino ADC and DAC features to realize a full-fledged multichannel anayzer with only a few common components allowed to operate a used NaI scintillation counter (from Ebay) and compare the ...

Finally, I need an analog soil moisture sensor so that I can monitor the soil moisture, and based on that, I can switch on/off the water pump remotely through the Blynk app. The below block diagram ...

Enables autonomous driving of a 2 or 4 wheel car with an Arduino and a Adafruit Motor Shield V2. To avoid obstacles a HC-SR04 Ultrasonic sensor mounted on a SG90 Servo continuously scans the area.

This paper presents a comprehensive review of solid-state metal pH sensors, with an emphasis on the potential of metal nitrides to address the limitations of glass electrodes and metal oxides. Metal ...
