3. Purecrea XY Joystick Module
This XY joystick module is comparable to a PS-2 game controller. The joystick features not only analog XY signals but also a button that is activated when the joystick stick is pressed. The output of the joystick coordinates is analog and occurs via two outputs. To evaluate the XY signals, two analog inputs are required on the Arduino. Additionally, a digital input is used for the button. You can use the joystick to control a robot, motor, menu navigation, drone, and much more.
Technical details:
Operating voltage: 5V
Signal XY: 2x analog
Button: 1x digital (without pull-up resistor, must be activated on the Arduino)
Size: 34 x 26.5 x 32 mm
Weight: 11 g
Delivery includes:
1x XY joystick module.
4. Purecrea HTU21D Temperature and Humidity Sensor I2C
The HTU21D is an affordable and accurate digital humidity and temperature sensor. Thanks to the I2C interface, you can easily read the humidity and temperature. This sensor is perfect for a weather station or any other applications where you want to measure humidity.
Important Info: Activating the I2C pull-up resistors: There are two 4.7 kOhm resistors on the breakout board that pull up the SDA and SCL lines. If you want to operate multiple sensors on I2C, only one breakout board should have the resistors. On the HTU21D breakout board, the resistors are not connected to VCC by default. To activate them, you need to connect the three solder points on the top of the board with solder.
Technical Details:
Operating Voltage: 1.5-3.6 V
Interface: I2C
Humidity Measurement Range: 0 to 100 % RH
Temperature Measurement Range: -40 °C to 125 °C
