Hi again,
I have designed something that supply 0 to 5 volt by using LM317 and LM337. Details are given in attached files.
My question is:
When I built this circuit on Porteus, it works very well. Proteus ss is attached. But when I create this in real life, it does not work. Why? Where and what is the problem/s?
I must supply everything with one 9 V battery or adaptor. How should I connect all grounds including Arduino's ground?
After getting 0 to 5 V, I am gonig to connect 3 diodes and a 8.2 ohm resistor at the output. I need 250 mA through this circuit (3 diodes and a 8.2 ohm resistor) when output of LM317 is 5 V. Where can I connect this circuint's (3 diodes and a 8.2 ohm resistor) gnd?
Thanks in advance.
Note: The potanitometer in Proteus represents output of DAC.
