For my engineering class, I am building a digital scale. My team has assembled the prototype out of:
- Arduino Uno
- Hx711 amplifier module
- 1 kg load cell
- 2 push buttons
- A 4 digit 7-segment display module we found online, but we don't know its specific name
- HC-05 Bluetooth module, no specific manufacturer
- Lilypad switch CR2032 battery module
- DC-DC step up to 5V boost converter module
Our prototype works. Well, sort of (we're still trying to work out the boost converter and c2032 to work). We have diagrammed how each module connects to each other on a piece of paper. However, we want to properly diagram this in a way so we can create a PCB for it.
I have tried the Eagle and Fritzing programs. I am very inexperienced with them. I am not able to find the HC-05 and LED display .sch or .fzz files online for this, so I have came to a halt. I am not sure how each of these modules are actually wired together either.
What can I do next?
