I have a project I want to create and I do not know which board to buy.
I want to create a wearable device (possibly a belt clip) with the following capabilities;
- can detect light and temperature
record physical steps of the user
uses a small OLED screen to display information, menu, and animations
power button for screen only
3 button interface
a rechargeable or replaceable (battery) power source
internal memory for saving progress in case of interrupted power
I know a little context would help with my request. I want to create a fitness aid device. Something that is aware of the world around it through sensing light, temperature, movement, and can tell the time. The ability to count and record steps are important so not only does the device know its moving, the user can meet a fitness goal through its use of counting steps. I would like to display different animations based on sensory input (movement, light, temperature) plus the time of day.
Currently, I am playing around with a Raspberry Pi SenseHat. But it has its limitations for my idea; namely its size and low detail provided by its 8x8 LED screen. I can make it portable; but after adding a battery, detailed screen, and light sensor it is bulky.
I've downloaded Arduino to get started but I need to know the right board before I get very far. I want it small, but size can be sacrificed over safety and functionality. I am fine if the final product ends up the save of a fancy cowboy belt buckle with a thickness of around one inch. At that max size, I could get away with bigger power supply or screen, and use the excess surface to turn it into wearable art.
Besides answering my inquiry; any thoughts, suggestions, and corrections are very welcome.
