Connecting 8 segment displays to the Raspberry Pi Pico with 74HC595 shift register
Sorry for the bad audio and choppy video
In this video I connected the raspberry pi pico to an 8-segment display. Since I will be using 4 digits and each digit uses 8 input pins I used shift registers (74HC595)
As with the rest of the videos in this temperature probe series I am using micropython.
In the next video in the series I will start working on getting the temperature from the probe to display on the display modules.
