An interesting project using newly Crowtail modules you can’t skip

An ordinary hat just can be the sunshade and it is not so useful for the workers who works outside on high place. Thus I want to remake a hat with Crowtail modules for 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.

First you will need to collect all the modules: a base shield which has stranded interfaces for convenient connection. Then is a Crowduino which is 100% Arduino compatible. UV Sensor to measure the UV intensity of the environment. Buzzer to make noise to remind user and RTC that can provide the right time in low power consumption. You will need a RGB-LED has the warning function. Users can control all the LED with only one microcontroller pin. OLED to display the time information and the UV intensity. Battery is essential.

Then, you can start this project step by step as follow: install the Crowduino. You need to sew the Crowduino onto this cap carefully at first to make it steady. You need to plug the Crowtail- Base Shield into Crowduino. Connect the buzzer to the Crowtail- Base Shield and connect the buzzer to the Digital ports D4 as picture. Via this buzzer, you can control the OLED to see whether it is displaying the current time and UV intensity or not.

Install the RGB-LED onto the cap. Crowtail - RGB-LED has the function of warning and when reach the designed time, such as 8:00 pm, it will start blinking automatically. Users can control all the LED with only one microcontroller pin. Besides, this module can control every LED with different colors at the same time.

Install the UV Sensor. The Crowtail- UV Sensor ML8511 is an easy to use ultraviolet light sensor. The MP8511 UV (ultraviolet) Sensor works by outputting an analog signal in relation to the amount of UV light that’s detected. This breakout can be very handy in creating devices that warn the user of sunburn or detect the UV index as it relates to weather conditions.

Install the RTC. This tiny RTC module is based on the clock chip DS1307 which communicates with microcontrollers with I2C protocol. The clock/calendar provides correct seconds, minutes, hours, day, date, month, and year information in very low power consumption.

Install the OLED. It is used to display the time information and UV intensity. It’s IIC interface to connect I Port (IIC Port). The display can offer high brightness, self-emission, high contrast ratio, slim/thin outline, wide viewing angle, wide temperature range in low power consumption. Choose the 9V battery. It is not only in small size but it can supply power in a long time. 

Download the Firmware. Use USB to connect the Crowtail with computer and open the program. Choose your COM interface connecting with Crowduino, here we choose COM3. Choose the target board. Here we use Crowduino. Upload the program as picture.

After all the steps finished, you can check every step to see whether there is a problem or not and welcome to contact us. Then have a try to see the effect. With this Arduino intelligent cap, you can have more function s and use it in your daily life. It’s believed that it can be of great help. Besides this project, you can also have a look at the previous Arduino project also make full use of Crowtail modules to care a flagging tree.
