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 ...

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 ...

Abstract: Passive infrared (PIR) sensors are widely used in motion sensing and lighting control. However, stationary occupants always trigger false-negative detects of PIR sensors and result in ...

Tired of your old Arcade games which all looks and works in the same way? Want to create a quick fun game which you can enjoy with your friends and family without using any thought? You are at the ...

The library gives control over up to 16 parallel working PIR devices over I2C. The idea for this library came up in a discussion about how to fully cover an area with PIR sensors without blind spots ...

Abstract: In this paper, we use a modified passive infrared radiation or pyroelectric infrared (PIR) sensor to classify 5 different human motion events with one additional “no action” event. Event ...

Connect a 4k7 Ω pull-up resistor between the 1-Wire data line and 5V power. Note this applies to the Arduino platform, for ESP32 and 8266 you'll need to adjust the resistor value accordingly. For ...

The illumination LED lights up or blinks in response to remote control operations and lights up in different colours according to the status of the TV. Yes, but it's not advisable. Without the LED ...
