hi bb,Dual OP-Amp (DOPA), Lol. Thanks eric, I'll be waiting.
Thanks Eric,
Just to clear things up. All 3 pins of the trimpot will be used this time right?
Leg #1 connected to ground.
Leg #2 (wiper) on pin #4 of LM3914.
Leg #3 on pin #6 of LM3914.
Is this correct?
The LM358 I bought were cheap chinese replica of the original National and Fairchild versions as they are the only ones available. So I don't expect them to be of accurate specs.
Hello Eric,
Everything's working perfectly now. Its now even attached to my motorcycle... really looks good and functions awesomely! Thank you so much. I'll be observing the project for a few days if anything weird might happen. Fuel sloshing will be observed also.
Next: Digital Speedometer on a PIC16f84a with 3 multiplexed 7-segment displays. I will be needing your help on how to tweak a bicycle speed sensor (from a broken cateye, magnet type sensor) to convert its output that is acceptable and countable by the MCU.
Hii Eric, can use 7805 as main voltage ?hi,
I will look and get back to you.
EDIT:
This should give you a quick solution, if not let me know.
If you have a larger value than100uF [ say 470uF] it will be ok to use it.
