The LM3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10 LEDs, providing a linear analog display. A single pin changes the display from a moving dot to a bar graph. Current drive to the LEDs is regulated and programmable, eliminating the need for resistors. This feature is one that allows [...]
The quickest way to display something is probably sending the data to the computer to be displayed on the monitor. One of the ways to do this is to use the USART module on board the PIC Microcontroller by making use of the pins RC6 and RC7 which is also the TX and RX pins [...]
This Led chaser is built using some very common digital logic circuits. Easy to build, easy to work with, and looks amazing in the dark. This circuit will light each led in sequence, creating a moving light illusion.
This is a very simple circuit to build, just take note of the control pins on each IC, [...]
