The engine has no framebuffer at all. Instead of drawing a picture in memory and sending it out, the Uno works out every line ...
On its 1000-ohm tap it needs only about 3 mA for full scale, so the ESP32 drives it straight from a GPIO with PWM, with no ...

Role in this project: sets the motor's speed. The Arduino sends a PWM signal to ENA; the L298N switches the 12 V supply across the motor at that duty cycle. Each channel of the L298 has four bipolar ...
There are plenty of “robot” projects out there that are really just a small remote control platform of some sort. We often like to think of robots of having some sort of autonomy though. [Luca Fagioli ...
When you’re tinkering with ESP32 microcontrollers, choosing the right setup can make the difference between a smooth-sailing ...
A simple circuit adds a relevant status-reporting bit to the device's existing already-sizeable capabilities suite.
