Input devices

Potentiometers are well known all around, and the sliding potentiometer is just one of its versions.You’ve probably seen it in some music equipment, and now you have the chance to add it to your project!

• Type: linear
• Resistance: 10k
• Dimensions: 86 x 22 mm

ADC (Analog Digital Converter) is a device that reads analog signals (just like the analogRead () function in Arduino IDE) and converts them into digital signals that can be read by a microcontroller. This breakout is based on the ADS1015 ADC, which reads values in 12-bit resolution, receives a maximum of 3.3V on its inputs and has a total of 4 channels (which can also be used as two differential). Works great with any microcontroller at 5V. It has 2 easyC connectors for easier connection on I2C communication.

Joystick module is well known to all – it is identical to the one found in the PlayStation2 joystick. Whether you are making a game with a microcontroller or want more freedom while navigating a joystick module will come handy.

It reads X and Y position of the joystick knob (used for controlling) and whether the joystick is being pressed down. X and Y values are shown in the form of analog values while reading off if the joystick is pressed or not is shown in the form of digital value (HIGH/LOW; it has pull-up resistor).

Are you short on IO pins? Looking to increase the number of them? That’s what the GPIO Expander MCP23017 is for! It uses I2C communication to do so. With just two wires, 16 new fully configurable digital IO pins are added to a microcontroller.

Due to the jumpers on the board, the I2C address of a device can be changed. Thus, eight breakout boards can be connected to a microcontroller. All of the pins on the expander board have pull-out resistors that can be turned on and off.

ADC (Analog Digital Converter) is a device that reads analog signals (just like the analogRead () function in Arduino IDE) and converts them into a digital signal that can be read by a microcontroller. This breakout is based on the ADS1115 ADC, which reads values in 16-bit resolution, receives a maximum of 3.3V on its inputs and has a total of 4 channels (which can also be used as two differential). Works great with each microcontroller at 5V. It has 2 easyC connectors for easier connection on I2C communication.

A mini version of our larger membrane keyboard that will still be sufficient for projects that need slightly less input.

• The size of the upper part: xcm x xcm
• Cable lenght: 9cm, flexible
• Connector: 5-pin

This adapter will help you connect our fingerprint sensor with ease.

Matrix keyboard is a system of 12 buttons that are interconnected that allowes us a more complex data input on Croduino/Arduino. With this keyboard you will create whole systems of menus, data entry and settings of various parameters.

• Dimensions: 70 x 50 mm

All real machines have an emergency stop button when pressed the whole machine stops. It can be very useful in case of the danger of someone working on that machine. If you want to install a similar thing on your project, here it is!

• Type: DPST
• Maximal voltage: 660V
• Maximal current: 10A
• Button diameter: 40mm
• Mounting hole diameter: 22mm
• Dimensions: 60 x 70mm

Although many do not know, there is a camera that can work with Arduino / Croduino. It is a CMOS camera, with VGA quality images that are connected to Croduino via I2C. Now it’s your turn to think of the application! Maybe combine with a motion sensor that could be activated if you someone entered the room?

The membrane keyboard is a system of 16 keys that are mutually connected and enable us more complex entry to Dasduino/Arduino. Using this keyboard, you can create whole systems of menus, data input, and adjustment of different parameters.
