An Arduino library for 7-segment display modules based on the TM1637 chip, such as Seeed Studio's Grove 4 digit display. The TM1637 chip also has keyboard input capability, but it's not implemented in ...

A wire is connected from a pin on the Arduino, to an LED via a resistor (to protect the LED from high current), and finally to the ground pin (GND). When the pin is set to a HIGH state, the ...

In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

Abstract: This paper proposes a boost-integrated two-switch forward ac-dc light-emitting diode (LED) driver with a high power factor and ripple-free output inductor current. In the proposed LED driver ...

Drones are widely used across several fields, including aerial photography, surveying, inspection, agriculture, and ...

Abstract: This paper presents the characterization of a carbon-doped gallium nitride (GaN) photoconductive semiconductor switch (PCSS). A novel method was devised to study the devices’ dynamic ...
