64x16 Big LED Matrix Clock / Temperature

Sure Electronics 0832 displays X 4 connected together to make a large led matrix display.

I built the interface on veroboard using a PIC16F913 @ 20MHz, DS1307 Real Time Clock & LM35 Temp sensor to gather the time and temperature and send the infomation to the display modules.

This also has a LDR to adjust PWM of the display acording to the amount of light in the room.

Nice, but is it fast enough to display seconds?

I belive its fast enough to display seconds, I havnt tryed this, as adding seconds would mean more displays or reducing the size of the digits.

Could you please tell me how do you control the led matrix, do you use a dedicated led matrix chip ? Thanks.

thats really awsome, i just ordered a bunch of arduino gear to do something like that, have you thought about using the : as a seconds timer? like it turns on and off counting seconds?

Bellissimo!!!

@wellyb00t PLEASE ADD THIS DIGITAL CLOCK TO UR WEB SITE ,, I REGISTERED THERE BY THE WAY AND MAKE THE LED CUBE U HELPED ME SO MUCH .. PLEASE I WANT TO MAKE THIS DIGITAL CLOCK TOO

Amazing project. As a novice PIC programmer/fanatic, I would love to be as good as you one day.

WOW this is a very cool display. Good work!
