These devices have key drawbacks. Water level indicators require manual pump operation and often waste power as multiple LEDs ...

Perfect for beginners, this all-in-one package includes essential components like sensors, relays, LEDs, and more, making it ...

After some time the controller turns the servo again in the opposite direction to close the dustbin, then the whole process is reapted again. The image below shows the Arduino circuit diagram for ...

We must ensure the components are connected correctly as per the above circuit diagram. Note that we can't directly drive the water pump from the Arduino UNO R4 Wi-Fi peripheral pins. For that, we ...

We have received the Seeed Studio 2-Channel Wi-Fi AC Relay for review. It is an IoT/Smart Home device featuring a 2-channel relay (wet contact) that operates over a WiFi network, and provides an ...

The ultra-low-power series is targeted at energy-constrained applications, powered by a battery, ultracapacitor, or power harvesting circuit. These include building control ... These boards support ...

With energy costs skyrocketing, any contribution, however small, to reduce energy consumption has got to be welcome. I noticed that a relay with a coil designed for use from an AC mains supply will ...

This repository contains the scripts that produce the libraries included with esp32-arduino. Tested on Ubuntu (32 and 64 bit), Raspberry Pi and MacOS. Install the ...
