Murata IRS-0D200ST00R1 tiny, low-profile SMD PIR motion sensor measures just 6 x 6 x 2.6 mm Murata SMD TYPE IRS-D200ST00R1 is one of the world’s smallest PIR motion sensors at just 6 x 6 mm in size ...

An Arduino Nano is in charge of reading the sensors. When it appears the car is approaching a wall or similar obstacle, it fires off a PWM signal to the car’s motor controller commanding it to ...

Apple Watch Blood Oxygen Sensor Returns: How to Use It and What It Can Tell You About Your Health The smartwatch's Blood Oxygen app lets you measure the oxygen level of your blood on-demand. It's ...

Arduino has created a Renesas RA4M1 microcontroller board in its Nano form-factor. Called Nano R4, it follows the Uno R4, the first Arduino to use the RA4M1. “Whether you’re working on a connected ...

[Roni] programmed an Arduino Nano R4 to estimate Pi using the Monte Carlo method. For this specific case, it involves drawing a circle inscribed inside a square.

This study experimentally examined the energy usage of the ESP32 and Arduino Nano microcontroller boards in active and deep sleep (power-down) modes. Both boards were powered by a continuous 5 V ...

Arduino-based motion-controlled game using a TFT display and IMU (gyroscope + accelerometer). Players tilt the device to guide a ball toward targets while avoiding obstacles. Features Kalman filter ...

Due to an ongoing ban in the US, measuring blood oxygen can be complicated on the Apple Watch. Discover the latest and more with this guide.

The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the collaboration of ...

The transition from human-centric to machine-centric vision systems demands innovative imaging architectures. Compressed imaging, using key mathematical transformations to capture essential visual ...

Cognitive functional therapy with or without movement sensor biofeedback versus usual care for chronic, disabling low back pain (RESTORE): a randomised, controlled, three-arm, parallel group ...
