| Feb 17, 2022 at 18:33 | comment | added | dbmitch | I guess I'm not very good at translating my breadboard circuit to the actual circuit diagram. It appears to look like what I'm doing with my tangle of wires. Which part do you think is wrong? I just haven't connected the last wire to GPIO - but it shows 2.34V steady. | |
