The schematic shows the current to be adjusted through a potentiometer. I wish to adjust the current by way of microcontroller (for example through a DAC).
I realized that I haven't attached a circuit schematic. The circuit I used it the constant current source straight from the LM317 datasheet. I'm leaving this open for interpretation; hopefully, we'll see some interesting circuits :-).
Hi.
I'm designing and implementing a NiCAD battery charger for fun. So far, I have my LM317 outputting approximately 1.2 A in a constant current source configuration. My question is how do I modify it to be an adjustable constant current source (say through my microcontroller) so that once...
