Topic: How to connect multiple tm1637 based 7 segment display in one arduino (Read 375 times) previous topic - next topic


       I am jst beginner in aduino programming but pretty fascinated by it. I m making a digital clock using 6 different tm1637 7 segment display module to display 6 different time. As there are 12 digital pins available in arduino uno board and only 2 digital pins are needed for each display module, i had a plan to connect all display module to single micro controller..  Bt i have searched a lot and was not able to find an example that connects more than one tm1637 display module to arduino..  Can somebody help me out...  Hoping for any suggestion..  :)
