Hi, can I ask where I can create a schematic diagram for free for my capstone project?
I will be using the following components:
Thank you.
for one.
Search "free online schematic drawing arduino"
Thank you
I would also recommand EasyEDA, but Wokwi is another good solution for simple schematic
Not only the cad systems - look at how schematics are laid out , where to put power connections , signal flow etc .
Nothing wrong with paper and a ruler .
Google how to … lots out there .
Normal design practice is to find a problem then pick the components you need to build it. It appears you have the parts and are looking for a project?
I found this on the internet: A capstone project is a final assignment that allows students to demonstrate their knowledge and skills by applying what they've learned throughout their academic program to a real-world problem or comprehensive research project. It typically involves selecting a topic, conducting research, and presenting findings, serving as a bridge between academic learning and professional practice. From what you presented you have a long way to go.
I recommend the KiCad system, it is well supported, and surprisingly good. It is free and will take you from schematic capture through the Gerber files for printed circuit boards.
Late reply, but in case it helps you or anyone who finds this thread later: I make a free, open-source tool called Circuit Sketcher (disclosure: it's my project). It runs in the browser with nothing to install: Circuit Sketcher - Web App or if you are using Obsidian, Circuit Sketcher - Obsidian Plugin
What may matter for your parts list: modules like the ESP32-CAM, the ultrasonic transducer or the vibration module don't have to exist in any library. You can turn a photo or drawing of the board into a part and put its pins where they are on the real board. The basics (resistors, capacitors, diodes, LEDs, transistors, switches, power sources) are built in, and wires route themselves when you connect two pins.
To be clear about what it isn't: it doesn't simulate and doesn't do PCB layout. If your capstone needs a formal schematic or a board later, KiCad or EasyEDA as suggested above is the right path. This is for a clear diagram of how the modules are wired together.
