Longwave atomic clock receiver modules are usually built for one specific carrier frequency. Two of the most important frequencies are 60 kHz and 77.5 kHz. A 60 kHz receiver can be used for time-signal systems such as WWVB in North America, MSF in the United Kingdom and JJY60 in Japan. A 77.5 kHz receiver is […]

Arduino shields made the original Arduino ecosystem very successful. A shield plugs on top of an Arduino UNO-style board and adds a function such as motor control, Ethernet, relays, prototyping space or a display. This approach is simple and familiar, but it also has limits. CANABLOX takes a different path. Instead of stacking one large

The ATtiny85, ATtiny88 and ATmega328P are all 8-bit AVR microcontrollers that can be used in Arduino-compatible projects. They are much smaller and simpler than modern 32-bit microcontrollers, but they are still useful when a project only needs basic control, a few inputs and outputs, or very low cost. This article compares the ATtiny85, ATtiny88 and

Microcontroller projects can get accurate time from several different sources. Three common options are longwave atomic clock receivers, NTP over the internet and GPS/GNSS time from satellite receiver modules. Each method can be accurate, but each one has different requirements and limitations. This article compares AM atomic clock receivers, NTP and GPS/GNSS time modules such

CANADUINO PLC modules are designed for users who want Arduino-compatible (Arduino IDE programmable) control hardware in a more practical automation format. Instead of wiring every input and output through loose jumper wires, a PLC-style module provides screw terminals, protected I/O options, power connections and a cleaner layout for real-world control projects. This article compares CANADUINO

The ATmega328P, RP2040 and RP2350 are all popular microcontroller choices for Arduino-compatible projects, but they represent very different generations of embedded hardware. The ATmega328P is the classic 8-bit Arduino controller used on UNO, Nano and Pro Mini boards. The RP2040 is a modern dual-core microcontroller from Raspberry Pi, used on the Raspberry Pi Pico and

Arduino-compatible projects can use many different display types. Character LCDs, OLED displays, TFT color displays and ePaper displays are all common choices, but they are designed for very different use cases. This article compares these display types from a practical project point of view. The goal is to help choose a display based on readability,

CANABLOX is designed as a modular development system. Instead of building projects with loose jumper wires and breadboards, CANABLOX uses standardized modules, clean I2C connections, baseboards and practical connectors. A project can be assembled from functional blocks such as a controller, RTC, display, ADC, DAC, keypad and I/O expansion modules. CANABLOX modules are sold separately,

When an Arduino UNO or Nano is no longer powerful enough, many users look for a faster 32-bit microcontroller board. Three common options are STM32 Black Pill boards, RP2040 boards and ESP32 boards. All three are much more capable than classic 8-bit Arduino boards, but they are not the same type of product. STM32 Black

OLED and LCD displays are both common choices for Arduino-compatible projects, but they behave very differently. OLED displays are self-emitting, high-contrast and often very compact. LCD displays use liquid crystal segments or pixels and usually depend on ambient light or a backlight. This article compares OLED and LCD displays from a practical project point of
