Arduino UNO The Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB ...

This sensor gives logic high (H) output when an object comes close to the sensor. This sensor only responds to 38 KHz modulated infrared light which makes it immune to disturbance caused by the ...

Working Principle of ACS712 Current Sensor with Arduino The ACS712 sensor operates on the Hall-effect principle. When current flows through the input terminals (IP+ and IP-), it generates a magnetic ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Circuit Diagram of Arduino Heartbeat Sensor Interface. Connect the VCC (power) and GND (ground) pins of the heartbeat sensor to the 5V and GND pins on the Arduino, respectively. Connect the Analog OUT ...

Smart Blind Stick using Arduino Circuit Diagram. The below circuit diagram shows the complete hardware wiring setup of the Arduino-based Smart Walking Stick for the Blind people, detailing how the ...

Because of the affordability and seeming ubiquity of the Arduino platform, they have been hard at work this last month trying to get their Geiger counter sensor board for an Arduino out the door ...
