Can I use a L293d ic with my 3 volt motor, or is 3 volts too low? If I can, than do I need to attach a separate source of energy or use any resistors? Please help as soon as possible, and thank you in advance.
Hi and welcome.
That chip "eats" about 1.4 volts per output, and you are using 2 outputs if you want to control a motor's speed and direction.
That means you'd need to supply it with about 5.8 volts to have that motor run close to specifications.
It also means it is quite inefficient to do that.
The L293d can supply 0.6 A if i'm not mistaking.
That 3 volt motor doesn't need that much or more, does it ?
So does that mean I have to supply 5.8 volts to Vs (pin 8 of the L293d) and Vss (pin 16 of the L293d)? Also, the 3 volt motor only needs 0.2 A.
No.
You supply the motor(s) through VCC2, and the logic is supplied through VCC1.
VCC1 is typically 5 volts.
In this case VCC2 can be 6 volts (which is easier to get than 5.8 volts), my guts tell me that those 0.2 volts extra (7 %) will not do much harm.
