I have a circuit that isn't working as it should. This circuit should convert a sin wave to a square wave, then the frequency of the signal should be divided by 10 using the HC4059. The signal looks very nice all the way until the HC4059. After that IC, the signal looks terrible from varying frequency. I need to know why this is happening and how to fix it.

Hi i’ve been learning about arduino from past month. i’ve made few basic and intermediate projects. My requirement is to make a Device which consists of SIM module Recorder Small size arduino So the idea is to make a device which records a voice and puts it on a server using data pack of sim. Initially a prototype is also okay using shields and all but for the final stage i want a devi...

We are working on a smart home arduino project and have different functionalities like, 1.
