Week.10 Machine Design

Assignment : automate your machine document the group project and your individual contributio

The components

Let's check first all the electronic components we needed to complete the machine.

The camera OV7670

I decided to buy a super cheap camera following advice in the internet. It was a mistake. Arduino does not have enough resources to manage it and trying to use a camera without a dedicated processor is a nightmare. There must at least one way to use it without FIFOprotocol, but I don't feel skilled enough to go into this field yet.

Managing so many wires into a project is problematic also from a physical point of view

Arducam REV C+

After long hours trying to connect a camera through a wire, my classmate Arnau gave me his own Arducam board... the best ever spent 30 US dollars in my life!!!

Arducam Library

It is so easy use it. You just need to install a library and all the example are already working. You just need to select the right camera which is plugged into the board.

Select your right camera, our is UC260 Camera / Arducam Yun OV2640

The boards connections

As the first Arduino board was busy for Arducam, I needed another board for programming the Stepper motor and the Switch/trigger input button. Input system bypassed the on board Trigger

From Arduino UNO to Arducam Board by a trigger wire connection.

The code

Stepper motor does a single turn of 360°, 24 hours, and trigger will detect only 6 input in a day, one per hours from 15.00 to 19.00

We have two codes, one is for Stepper motor and Trigger detection from switch button, the other one is the Arducam Code from library.
