They're reference designs for a reason.

Macropads can be as simple as a few buttons hooked up to a microcontroller to do the USB HID dance and talk to a PC. However, ...

Single-channel isolated gate drivers in the 1ED301xMC121 series from Infineon are pin-compatible replacements for optocoupler ...

Explore how a basic LED can be used as a tiny solar cell, generating measurable voltage under sunlight. This hands-on electronics project demonstrates the photoelectric effect using a multimeter to ...

This library is to control the I2C PCA9634 PWM extender. The 8 channels are independently configurable in steps of 1/256. This allows for better than 1% fine tuning of the duty-cycle of the PWM signal ...

Transport bosses are being urged to create an extra lane on the approach to Edinburgh's Sheriffhall roundabout in a bid to ease congestion while the wait goes on for a full upgrade. Did you know with ...

Most official Flipper features are implemented. I2C: INA219, MCP23017, OLED (I2C preferred to free SPI). IR (RX/TX) and speaker/vibro outputs work. MCP23017 handles buttons, RGB LED and vibro (pins B1 ...

Abstract: In single-phase ac/dc light-emitting diode (LED) drivers, a reduced power processing technique is currently being used to increase conversion efficiency while reducing the size and cost of ...

Abstract: This article presents a hybrid boost converter architecture for improving the efficiency of light-emitting diode (LED) drivers used in mobile applications. By cascading a low-switching ...

60+ years, thousands of cars, hundreds of tests—we've done the work for you.
