Arduino display module 7-segment 8 digits with MAX7219

Programmable digital timer switch using a PIC Microcontroller

Continuing the development of my UV exposure box I have designed and built a countdown timer. START/STOP the timer, UP – adds 10 more seconds, DOWN – subtracts 10 seconds, MEM – recalls some preset values from the memory. Because software allows flexibility in connecting the display, I chose to make the connections as easy as possible

Using the Real Time Clock. by Bill Earl. What is a Real Time Clock? (by checking the clock) or noting at what time of day the data was logged. The Arduino does have a built-in timekeeper called the millisecond timer is set back to 0. The Arduino doesnt know its 'Tuesday' or 'March 8th' all it can tell is 'Its been 14,000 milliseconds

Arduino Real Time Clock (DS1307): 7 Steps

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds where a 1 is represented as a lit led. This project can be used in schools to display a binary number using leds.
