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 ...

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.

Well, as it turns out you can actually measure capacitance using your Arduino Uno, with no external components ... it sends a 5V pulse to the capacitor and measures the voltage on the other ...

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

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 ...
