Hi all. im new here and have a basic knowledge and wanting some help for a project im doing.
I want to convert my dash to a digital / led one.
I want the tacho as a circle of leds and if possible a number on a lcd/ led digit display in the middle and the same for the speedo, speed by leds and i numerical readout in the middle.
Would be good to do the same with the oil pressure/ water / voltage and oil temp. but ill work on one thing at the time as i think the basic circuit for each item is the same with slight modifications.
I have been looking at the 2 Chips , LM3915 led driver and lm2907 but not sure how to hook them together and how to output to more than more than 10 leds, would prefer about 20 leds and a 4 seg display for tach and 3 seg for speed.
Any help is greatly appreciated from you good experts.
Thanks in advance
