Projects General Guidance

I want to remake a hat with more functions such as detecting the UV intensity to remind user to have a rest, at the same time. this hat can also offer the correct time info for workers without a watch when working on high place. Moreover, this hat has the warning function of the behind vehicle at dusk way.

What you need are: Crowtail Base Shield, Crowduino, buzzer, UV Sensor, RTC, RGB-LED, OLED and a Battery. All these modules you can find from Elecrow.

Then sew the Crowduino on a hat and install the base shield on it. Install the buzzer and RGB-LED, UV sensor. Then is the RTC which is based on the clock chip DS1307 which communicates with microcontrollers with I2C protocol. at last, you should install the OLED and power supply on the cap. It’s IIC interface to connect I Port (IIC Port) to connect the UV sensor.
