This project employs an Arduino Uno along with IR sensors to count the number of people entering or exiting a room. It automatically controls the room's lighting based on occupancy, ensuring lights ...

The SparkFun Spectral UV Sensor - AS7331 (SEN-23517) and SEN-23518 features the AS7331 UV sensor from ams OSRAM©. It measures UV radiation on three channels: UVA (320-400nm), UVB (280-320nm), and UVC ...

Get close enough to this raven and you’ll set off the PIR sensor, which triggers lighting ... This bird’s brain is an Arduino Nano, which is protected from the 12V supply with a boost converter.

2.56 MHz. Note: higher speeds and longer wires need smaller pull up resistors. Some timings in micros for INA.getMode() on an Arduino UNO. This is just one readRegister call, similar to most functions ...
