I've been testing an Arduino Nano 33 BLE to test it's functionality with pull-down resistors. int testPin = 2; void setup() { Serial.begin(9600); pinMode(LEDG, OUTPUT); pinMode(LED_BUILTIN, OUTPUT); ...

This library (with examples) is designed to be integrated in projects using any kind of photocell to retrieve the light intensity (in Lux or footcandles). It handles the GL55xx photocell series but ...

A flex sensor is a low-cost, easy-to-use variable resistor that is designed to measure the amount of deflection it experiences when bent. The sensor's resistance is lowest when it's flat on the ...

A FORCE sensor is a transducer which changes its resistance when pressure is applied on surface. FORCE sensor is available in different sizes and shapes. We are going to use one of the cheaper ...

Integral to process control in many industries, level measurement sensors fall into two main types. Point level measurement sensors are used to mark a single discrete height (a preset level condition) ...

The security flaws on this common hotel keycard lock are nothing short of face-palmingly stupid. Look closely at the picture above. This is a hotel room door swinging open. The device he holds in his ...
