ApolloBlind 👁

⚠ This project is still in development.

👩‍🚀 The Repository

🚀 ApolloBlind is a repository of a project initialy based on Arduino Micro (ATMega32U4), to help the Visually Impaired. (Version 0.1).

Currently at version 0.2, we are trying to use the ATTiny82 microprocessor, with the PIR sensor and vibration motor, with 3V coin battery and Transistor NPN.

💻 Coding

Configuration of Sensor PIR1

We define a global constant for the PIR Sensor pin.

#define PIN_PIR A4

And we added a conditional in loop(), always checking if the PIR Sensor detected any movement at 3m.

int valuePresence = digitalRead(PIN_PIR);
if (valuePresence == HIGH){...} 
else if (valuePresence == LOW){...}

Configuration of Motor of Vibration M1

We define a global constant for the PIR Sensor pin.

#define PIN_VIBRATOR A1

When the PIR Sensor receives motion information, it outputs to the vibration motor port, otherwise nothing happens.

digitalWrite(PIN_VIBRATOR, HIGH);
digitalWrite(PIN_VIBRATOR, LOW);

🤝 Contributing

There are many ways in which you can participate in this project, for example:

• Submit bugs and feature requests, and help us verify as they are checked in
• Review source code changes

If you are interested in fixing issues and contributing directly to the code base or scheme, please see the document How to Contribute.

👽 Futures changes

• Switch from a prefabricated board (Arduino Micro) to a custom one, to lower energy usage. (ATTiny82)
• 🔋 Choose a battery for the ApolloBlind, or (3V Coin type Battery)
• 🔌 Make the device rechargeable.
• Add an ON/OFF button on the custom board.
• Build a cover in 3d structure.
