Flipper Zero: Output Analog Voltages!
In past videos we looked at ADC (Analog to Digital Conversion) on the Flipper Zero. This video looks at DAC (Digital to Analog Conversion) on the Flipper Zero. We look at three techniques to allow your Flipper Zero to output analog voltages!

Let me know if you know of a better Op-Amp. For LM324 in a unity gain amplifier configuration, connect the output to the Input- and then your signal to the Input+ pin. For example, pins 3, 5, 10 or 12 become the input and pins 1+2, 6+7, 8+9 or 13+14 become your output.
