This application required more flexibility than the LM3914 offers, and it uses a circuit based on an Atmel AVR-family ATTiny13 microcontroller, which features 1 kbyte of program memory; a four-channel ...
Microcontroller Displays Voltage Measurements in Graphical and Digital Formats via Single LED Matrix
The algorithm in this microcontroller design this design drives an LED matrix and provides digital-voltage-readout and bar-like dot displays, showing dots for a graphical output if the input value is ...
Now you can always know the exact time. With this design you can have an atomic clock in your room. Isn’t that great? Read on to know more. Now you can always know the exact time. With this design you ...
Seven-segment displays are needed in many instrument designs. In conventional microcontroller-based designs, four output port lines are allocated for one seven-segment display. Figure 1 shows the ...
Hackaday.io contributor extraordinaire [al1] has been playing around with small LEDs a lot lately, which inevitably leads to playing around with large groups of small LEDs. Matrixes of tiny RGB LEDs, ...
[Joe] tipped us off about his 112 LED coffee table. This 12-ups the LED matrix from Friday and 31-ups the Shiftbrite table. Driving this grid is an ATmega328 in i2c slave mode. It listens for display ...
