  • Hi, im new to arduino but im doing a project whereby i want to control a 3 digit seven-segment display with 74HC595 shift register and with an analog keypad input. how do i do the code because i have tried and nothing appears happens. im confident of my connection but sometimes my arduino has problems, it can't be detected by my computer and that has let to a few problems with uploading the code to the board so sometimes i get confused when my ardunio has problems or if the code is not the right one for my seven-segment. Can you help me with this?
