In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...
Abstract: A conflict-avoiding code (CAC) is a deterministic transmission scheme for asynchronous multiple access without feedback. When the number of simultaneously active users is less than or equal ...
AS5600 is a library for an AS5600 / AS5600L based magnetic rotation meter. More exact, it measures the angle (rotation w.r.t. reference) and not RPM. Multiple angle measurements allows one to ...
In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...
BMV080 is a low-power, low-cost PM1, PM2.5, and PM10 sensor module with I2C and SPI interfaces that sells for just $29.90.
Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based ...
Abstract: LabVIEW is a graphical programming language, used in many research fields for designing communication algorithms and simulating traditional as well as real time signals. Arduino kit can be ...
The I2CKeyPad8x8 library implements the reading of a 8x8 keypad by means of a PCF8575. Smaller keypads, meaning less columns or rows (e.g. 5x4) can be read with it too. Sometimes you need to control ...
For some people, the medications have transformed their relationship with physical activity. By Danielle Friedman Jamie Selzler dreaded exercise for as long as he could remember. Throughout his 20s ...
Some patients in a clinical trial of one new drug lost so much weight that they became concerned and dropped out. By Dani Blum Scientists raced to make drugs that help people lose as much weight as ...
Here we are designing a very small, tiny CAN network sensor that can be attached to any vehicle. It detects motion, accidents, and all vehicle activities in real time. It can also be modified to act ...
