The board was also added to the Arduino core for the ESP32 a few months ago, and a tutorial with a few Arduino sketches is also available. The feather-compatible ESP32-S3 board ships with three Grove ...

We are going to program the UNO to provide a PWM signal of different duty ratio for each of buttons. So we have a tone generator at hand which generates a different tone with each button press.

Connect the 9V using a 9V adaptor to Arduino Uno board and 9V battery for PZ1. Fig. 3: PCB layout of tone generator system Fig. 4: Components layout of the PCB Download PCB and component layout PDFs: ...

Arduino describes itself as an "open-source electronics prototyping platform based on flexible, easy-to-use hardware and software." If you're interested in maker projects, circuit boards, or just ...

Makers around the world have asked themselves the same question: where do I find reliable and easy to use circuit diagrams for my projects? I've spent years tinkering and making stuff with Arduino, ...
