Oldie but a goodie project from the Circuito.io team published over on Hackster.io

This project utilizes an Arduino Pro Mini, a servo, and a mini photocell (all of which you can grab over on our site) that opens and closes a 3D-printed sunflower in response to light. Very cool!

We have three new products to upgrade your keyboard or PID - Cherry MX2A Key Switches!

Available in Red (linear), Blue (clicky), and Brown (tactile), these swtiches are known for their precision, consistency, and long operating life, making them a standard choice for keyboard manufacturers, makers, and enthusiasts alike.

The MX2A generation builds on the original MX design with factory-applied lubrication, an optimized spring, and refined housing geometry to provide smoother key travel, reduced spring noise, and improved typing feel while maintaining compatibility with standard MX keycaps and PCBs.

Debugging Electronics Be Like...

Every person working with hardware has been there. You're convinced the hardware is broken... only to discover the problem was something simple all along.

The new SparkFun Current Sensor Boards help you monitor power consumption and verify what's actually happening in your circuit.

Sometimes the measurements confirm exactly what you hoped... and sometimes they confirm you plugged the LED in backwards.

This week's topic: Getting [const] Data Out of RAM1 on Teensy Boards

On Teensy 4.x, const doesn't always mean what you might expect. It tells the compiler your data should not be modified, but it does not automatically mean the data will live only in flash.

A constant command table can still consume RAM on Teensy 4.x. Read to learn how to correctly store both your lookup table and its strings in flash.
