Hey All,,
Need a help from the expert of you. I have a project to build an up/down counter with ic 555 timer and using any ic for the counter. I choose CD4510, because it is presetable up/down counter. The task is to build a counter, when the input voltage is greater than 3V, it will count up 0-15. Otherwise, less than 3V it will count down, 15-0. For counting up from 0-15, it is successfull run. However, it gets stuck when I tried to count down from 15-10. I have preset the input number of two counter as 0001 (1) and 0101 (5) as well have set the PRESET ENABLE to HIGH, but it didnt count down. I need help from someone to correct my project.
I attached the picture of my circuit design. Please anyone help me to figure it out the problem. Thank you in advance..
