For Power supply purposes, I decided to use a 12V DC Power Adaptor to power this whole setup through a barrel jack connector. In the below image, you can find our actual hardware setup of our ...

Connecting the water flow sensor to arduino requires minimal interconnection. Connect the VCC (Red) and GND (Black) wires of the water flow Sensor to the 5v and Gnd of Arduino, ... to the ...

So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project.

The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

TCS3200 Color Sensor Working. The TCS3200 color sensor is used to sense a wide range of colors. We previously interfaced TCS3200 color sensor with Arduino and Raspberry pi, and also built some useful ...

Simple counter that shows on 7 segment display and serial monitor - eesur/arduino-counter-with-display ...

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 ...

Schematic of the Arduino and TC74 sensors circuitry. Advertisement. Advertisement. Partner Content. Power your devices through universal USB-C 48 V rail, Hynetek brings new USB PD3.2 DRP Controller.

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.
