#106755 - auto reset Responding to: ???'s previous message |
The ULN2003A is used to drive 2 fans and 2 LEDs while the other LEDs are driven by just 3905 BJT transistor. When the power is switched on, the 2 fans and 2 LEDs driven by ULN2003A are off while the other LEDs are all on.
I have not used any reset chip, but a reset button. Is that I can make the circuit reset automatically once the power is switched on if I use a reset chip? Any additional code needs to be added if so? Also, any way to solve the LEDs on problem once the power is on(for those driven by the 3905)? Can I make the start with all the things off? Thanks! |
