The 70 mm x 60 mm board, which comes with a MAX40661 transimpedance amplifier, is designed to accelerate design and ...

Light sensors detect the presence or absence of light, and the intensity of that light. These sensors then convert light ...

Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

Aside from the Uno and the ultrasonic sensor, you also need a PHPoC Shield to connect the board to the internet and a power supply to power up your Arduino.

It's important to have a grasp of how to read Arduino resistors, as they're useful for controlling the current in an electrical circuit.

Unlike high sensitivity fixed-gain IR sensor modules that require attenuators like dark panels, apertures, and sunshades to protect them against sunlight — adding to overall solutions costs ...
