Similar problem as bfrivers on 2022-04-22 at 12:19 reply #2071:
“We finished the assembly and went to test it; however, there is an issue we can’t identify. When we turn the machine on, we hear a brief beep, but the led board does not light up and neither do the digits.” The keyboar function C turns on the red dots on the digits between the rotors. “The keyboard special functions (K, L, etc.) do not work as well.”
“There are red lights on the Arduino, the DC boost converter and the RTC. I’m reading about 4 volts between A5 and SDA (pin 27 on ht16k33) and 4.5 volts on A4 and SCL (pin 26 on ht16k33).”
WHAT ARE OTHER THINGS WE CAN DO OR REPLACE?
THANKS.
