Hi, can somebody send me schematic for the project i want to build please?
I want to build an lm3915 counter up and down by pressing button for up or button for down.
I want the leds to go on 1 by 1 till all 10 are on and then if press the down button the leds to go down one by one.
I managed to build one by schematic i find on the google but the down counter doesn't work properly and if you count till up and let it the led will go down by itself as the capacitor dries.
Can someone make proper counter by LEDs?
