How microcontrollers and single-board computers coordinate high-speed RF acquisition and generation. How SCPI and UART commands let simple controllers use advanced measurements without FPGA ...

When you think of Arduino projects, your mind likely goes straight to RFID door locks, weather sensors, or automated plant watering systems. While these are undeniably pretty cool projects, you might ...

This library very simply generates a set of channel symbols for JT65, JT9, JT4, FT8, or WSPR based on the user providing a properly formatted Type 6 message for JT65, JT9, or JT4 (which is 13 valid ...

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 ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

The RejsaCAN-ESP32-S3 is an ESP32-S3 board suitable for developers who want to build a car-related project. It can control or read the data from the OBD-II connector in your car using 2.4 GHz Wi-Fi or ...

As shown in the block diagram above, the Coin acceptor module acts as the input device which gives the signal to Arduino when it detects a valid Coin inserted within it. Arduino receives the signal ...

I built a DIY oscilloscope & spectrum analyzer for my modular synthesizer using an Arduino and an SSD1306 OLED, so here is a memo of the project. This is the 25th project in my DIY modular synth ...

Most embedded systems are reactive by nature. They measure certain properties of their environment with sensors and react on changes. For example, they display something, move a motor, or send a ...
