This project proposes the creation of a standalone alarm system based on an Arduino Nano board (ATmega328P) combined with a BK A7670E 4G GSM module. The system allows for remote activation and control ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

LILYGO T-Connect Pro is a DIN rail-mountable, ESP32-S3-based industrial IoT controller with Ethernet, WiFi 4, Bluetooth 5.0 LE, and LoRa connectivity, as well as CAN Bus, RS232, and RS485 interfaces.

Fire safety alarms are crucial in both residential and industrial environments. Early fire detection can prevent significant damage and save lives. Flame sensors offer one of the most efficient ...

The presented solution for measuring voltage of Zener diodes using Arduino is completely new and original. The circuit uses LM317 as a constant current source and the whole measurement process is ...

The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now ...

I would like to turn on my car's heated seats over a mobile/cellular network using my iPhone, and I'm trying to figure out the simplest path. I know very little beyond that goal, but I know that RF, ...

I have noticed that almost 98% of my horn usage is actually to make very quick and short chirps. BHPian clevermax recently shared this with other enthusiasts. This thread will detail how I automated ...

In the past few decades, aquatic animals have become popular model organisms in biology, spurring a growing need for establishing aquatic facilities. Zebrafish are widely studied and relatively easy ...
