HT16K33 14-Segment Display

[@deadcertainty4528]

A crystal-clear explanation and tutorial. It could not have been better! Thank you so much for taking the time

[@ejennings98]

Very well done! Clear and direct example which any programmer can follow.

Thank you

Nice, Great video (as always!)

Adding a strip of 5% car window tint film in front of the display makes it much easier to read in most lighting conditions.

It is also available with 7 segment LEDs. There, instead of 16 bits, 8 bits are written for each position.

This is great...however I have a problem. I've done exactly everything even to the code, and its only recognising 1 side rather. So both 4 digits connected up are doing 0123...0123, intead of 0123...4567. It seems to be running parralel. Is there other pins to this to use? It won't work on A4, A5. Only on SCL and SDA. Thanks

Both displays are set to the default hardware address (0x70), so both are responding to the commands intended for the first display. To get the second display to respond to the commands intended for it, you must set the hardware address of the second display to 0x71. The hardware address is set by soldering jumpers across the three pairs of pads on the back of the display. The pairs of pads are labeled A2, A1, A0. The absence of jumpers produces the hardware address 0x70 (the default). Soldering a jumper across the A0 pair of pads produces the hardware address 0x71; a jumper across A1 produces 0x72; jumpers across both A0 and A1 produces 0x73, etc. (Yes, I know - the pads and jumpers are very tiny!!)

Is it possible to change the analog pins? I need to use more that 7 of these so i need 4 analog pins in totall. Or is there another way?

[@AnasKuzechie]

You can interface max 8 of these displays. I have a video where I created a library that enables you to achieve this.

[@bilbobaggins138]

@@AnasKuzechie Sorry i mean i need more than 8. I need to use about 16 of them (maybe more) and preferably on the same arduino

[@AnasKuzechie]

@@bilbobaggins138 your are limited to 8 per Arduino, since max 8 I2C addresses can be used.

[@alexle3598]

also its great example of how i2c protocol works
