Before starting the Arduino robotic arm project, it’s important to understand a few fundamental concepts that apply to almost every robotic arm design. These terms will help you plan better, avoid ...

Third PWM fan goes full speed, RPM controls not working and changing pins also doesn't tho 9th and 10 pin works fine. It seems that app only likes 9th and 10th pin. The Arduino I am using is Arduino ...

SAN JOSE, Calif.--(BUSINESS WIRE)--Power management leader, Kinetic Technologies, is expanding its portfolio with the introduction of KTB2140. This single-chip, highly integrated active-clamp ...

The Adafruit Metro RP2350 is a Raspberry Pi RP2350 development board that closely follows the Arduino UNO form factor for compatibility with existing Arduino shields. Key features include 37 GPIOs, a ...

// 1) Read OEM push buttons to set the mode (33 RPM, 45 RPM, 78 RPM, Reverse, Start/Stop. // 2) Set the PWM to the H-bridge driver (L298N) via arduino PWM output based on the hall sensor RPM speed ...

When designing devices with microcontrollers (MCU), I like to use some of the analog-to-digital converter (ADC) inputs to measure onboard voltages along with all the required sensors inputs. This ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...

Sometimes it’s necessary to drive a resistive load such as an incandescent bulb or heating element from a DC voltage that’s higher than the nominal load voltage. An example would be driving a 6.3-V, ...
