This is a tutorial for the TinyCircuits TinyDuino platform, to learn the basics of the TinyDuino, click here.
The TinyShield Gyroscope features the high performance and lower power ST L3G4200D 3-axis gyroscope. The L3G4200D allows measurement of angular rates in three axes. There is also an integrated temperature sensor built in.
Powering the System
The ST L3G4200D is a low power device, drawing 6.1mA at full power mode, and can be configured to draw much lower current at slower operating rates. Due to the low power, a coin cell battery is sufficient to run this board.
The Gyroscope TinyShield includes a local voltage regulator and level shifters, so your TinyDuino system can operate from 3 – 5 Volts safely.
Using the Gyroscope TinyShield
The Gyroscope TinyShield uses the I2C bus to communicate between the TinyDuino processor and the ST L3G4200D. Below is a sample sketch to get the data for all three axises and display them on the USB serial port using Codebender:
