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 ...

The difference between high-side and low-side power switching is not apparent to many new designers but is a critical aspect of a viable circuit. Part 1 looked at the topology of high-side versus ...

After the success of PicoADK v1, Datanoise has recently announced the launch of its PicoADK v2 music synthesizer built around the Raspberry Pi RP2350 MCU. The board supports projects like custom ...

Needing to drive two devices with a DCF 77 signal, I made an NTP client time server with two output channels. Elektor published in its March-April 2018 issue an excellent article describing a module ...

Waveshare “ESP32-S3-Touch-LCD-4.3B” is a capacitive touch display development board built around an ESP32-S3 SoC with RS485, CAN Bus, I2C, and isolated DIO interfaces provided through a terminal block ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

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 ...

Discover the updated Arduino IoT water leak detector: smarter, more efficient, with advanced monitoring and alert systems for the modern smart home. Following the Elektor article presenting the water ...

We build the Arduino based Multi-house Water Pump Control System. Here we are going to explain step-by-step, how you can make your own Water Pump Controller. But before that, we need to understand why ...

Nowadays, you don’t have to be an engineer or electrician to make your own tools. Thanks to the technology available today and the wealth of information available, many problems can be solved.
