An Arduino Nano is in charge of reading the sensors. When it appears the car is approaching a wall or similar obstacle, it fires off a PWM signal to the car’s motor controller commanding it to ...

After this tedious step, he designed a PCB that hosts an Arduino Nano to accept input, two MCP23017 GPIO expanders to give it enough outputs, and CD4066BE CMOS switches to trigger the connections.

Despite the predictions of pundits who see digital functions as electronics' finest achievement, analog circuitry just doesn't go away. The laws of physics and the real world don't allow it. But the ...

The Evolution of Arthropod Nervous Systems: Modern insects and crustaceans diverged from an ancestor over 500 million years ago, but their neural circuitry retains many common features ...

I’d suggest that the smart glasses category really didn’t “get legs” until Meta and partner Ray-Ban’s second-generation AI Glasses, released in October 2023. Stories, the first-generation product ...
