Let’s start with the simple case: performing an action only when the switch goes active. We’ll assume the switch starts in ...

The QR code is so small, in fact, that it can "only be recognised with an electron microscope". As a result, the research ...

Arduino is a microcontroller designed for real-time hardware control with very low power use. Raspberry Pi is a full computer that runs operating systems and handles complex tasks. Arduino excels at ...

Total mastery over the pinout and functionality of the PCA9306 for conversion of logic levels from 5V to 3.3V. A step-by-step interfacing diagram for the PCA9306 to Arduino UNO. Working example with ...

Ever wondered if a small, low-cost board like the ESP32-CAM can actually recognise objects or even identify Indian currency notes? In this project, the answer is a clear yes. We combine the ESP32-CAM ...

This Arduino example code demonstrates how to set up and use the IQS323 Integrated Circuit (IC). The IQS323 is a 3 Channel Self-Capacitive / 3 Channel Mutual-Capacitive / 2 Channel Inductive sensing ...

Arduino is being acquired by Qualcomm subject to regulatory approval for an undisclosed sum. Qualcomm Arduino introduces a new UNO form factor board, the Arduino UNO Q, which features both a STM32 MCU ...

We may receive a commission on purchases made from links. While GE remotes are technically produced by a company called Jasco (as part of a licensing agreement with GE), the remotes are ...

In what follows, we will refer to these collections as “Breadboards,” “Tools,” and “Components” for short. For example, when working with semiconductors such as transistors, diodes (including ...

Introduction: Generative AI tools can produce programming code that looks very similar to human-written code, which creates challenges in programming education. Students may use these tools ...

We love Arduino here at Hackaday; they’ve probably done more to make embedded programming accessible to more people than anything else in the history of the field. One thing the Arduino ecosystem is ...
