7 segment display multiplexing arduino

The data bits are communicated uninterrupted and continuously with each bit transferred over every clock pulse. Some electronic components only require transmitting or receiving data. Sponsor this project. These are rather old chips now with some limitations compared to modern alternatives, but they are still very common, so if you have one to hand, it will do for this purpose. I have only heard of it being done, but another method still using only one current limiting resistor per digit, would be to multiplex at the digit granularity level, but to use pulse width modulation to even out the luminous intensity to prevent say a 1 appearing brighter than an 8.
