Planning Project Research

A run into error

Hi so you may have noticed on my previous blogs that my project suddenly made a component change and had a new component review blog. This is because during this project I was behind due to personal reasons. Due to that I was left during Christmas behind on schedule and when it came to building the circuit there were no tutorials or help I could go to during this time.

Below are the pictures of the schematic and what my circuit looked like when I couldn’t get it to work.

Schematic for melody shaper

I ensured that all the values of the components were correct such as the capacitor being at 100uF. Possible errors may be from how the jumper wires are connected. However my main speculation is that the battery is suppose to be the external power source plugged into the Arduino separately


I continued to rearrange the circuit in order to get it working however it was to no avail. It felt as if I was continuously going the wrong direction when looking for my destination. At times I nearly felt like giving up however I remember one thing, the power of the internet! Just one problem there were no tutorials at all on this. So instead I jumped to another project. This one.

This was called the Arduino mini piano. One key difference I noticed was the code programmed the push buttons to play individual notes rather than coded melodies that would play after being uploaded to the circuit. This was interesting as it made me notice that I could compile a pros and cons list for the two and compare them.

Project time!

I jumped straight into it, as you can see on the previous blog with the component review. Now it is time to build this new mini Arduino project and play the melodies intended.
