For backlighting purpsoe, 5V dc supply is fed to the backlight pins BL1 and BL2 (also labelled as LED+/BL+ and LED-/BL-) through a suitable current limiting resistor (for instance, with a 100-Ohm one) ...
Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...
Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM doe… ...
Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
