Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

A lot of making goes on in this community these days, but sometimes you’ve just gotta do some old fashioned hacking. You might have grabbed an old Speak and Spell that you want to repurpose ...

A hackerspace is a place that generally needs to be accessed by a wide group of people, often at weird and unusual hours.

The I2CKeyPad8x8 library implements the reading of a 8x8 keypad by means of a PCF8575. Smaller keypads, meaning less columns or rows (e.g. 5x4) can be read with it too. Sometimes you need to control ...

Arduino sketch for generating pulses needed to control servo drivers such as the AASD-15A used in the SFX100 project and the pt-actuators. The controller is meant for the SFX100 actuator and the likes ...

Building a DIY Arduino game controller requires specific hardware components. The table below lists all the components required to build the Arduino Uno game controller project. These components are ...

Abstract: Two-dimensional (2D) direction-of-arrival (DOA) estimation using sparse arrays shows advantages in reducing hardware costs and enhancing degrees-of-freedom. However, most current studies ...

Abstract: Two-dimensional (2-D) array sets with good 2-D correlation properties have received considerable attention in wireless communication systems. This paper focuses on 2-D Z-complementary array ...
