This sensor is relatively complex to set up, but it works with older Arduino boards like the first-gen Uno. Measuring the ... Counting your own pulse is a thing of the past with components like ...

This is used to read the output pulses coming from the water flow sensor. When Arduino detects the pulse, it immediately triggers the pulseCounter() function. This function then counts the total ...

Pulse-width modulation ... be communicated with using I2C from analog pins 4 and 5 on the Arduino Uno. We powered the sensor stick using the 5 volts out available on the Arduino Uno.

Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, but other compatible microcontrollers can also be employed.

you can just build it a custom sensor with an Arduino Uno. This paper shredder bin monitor is an easy Arduino project for beginners to get into. It uses an ultrasonic sensor, which is placed ...

An ultrasonic sensor is positioned outside the box to detect the presence of a hand within a four-inch range. Upon sensing an obstacle, it then sends a signal to the Arduino UNO, which ...

It lets you use not just one or three Arduino boards but seven — Micro, Pro Mini 3.3V, Pro Mini 5V, Leonardo, Uno R3, Nano R3, and Mega 2560 R3. There are also over 200 sensors and modules ...
