ZERYNTH Shield is a shield compatible with the pin-out of the Arduino and Particle and is natively supported by the development environment ZERYNTH. It has temperature sensors, sound, light, but also a capacitive touch and an IR receiver. It also has, of piezoelectric buzzer and an LED IR emitter (actuators). The communication ports on board SPI and I²C-Bus; complete the form a line and a Digital Analog Aux Aux, as well as a PWM output and a port for LED strips Neopixel Adafruit. The availability of sensors and communications ports used more ready for connection enables makers, craftsmen and designers to easily develop their applications without having to worry about the electric circuit, welds or loose wires in the breadboard. Just connect an Arduino Two or a Photon or ST Core to shield and start working with one of the examples ZERYNTH found in his library. Routing ensures compatibility of ZERYNTH shield with the most shields Arduino shield like Ethernet, Wi-Fi and BLE. The board ZERYNTH Shield is easily attached on top of the "stack of shield" without having any problem of compatibility of the pin.





ZERYNTH is a software suite for programming interactive objects, ready for cloud and the Internet of Things. ZERYNTH allows to develop in Python on most popular platforms for prototyping, using paradigms and features typical of high-level programming.

ZERYNTH is available for download as open source to the following address:


ZERYNTH Shield is compatible MultiBoard
  • IR receiver
The IR receiver is based on TSOP34838 component that can be used to read signals from common IR devices at 38 kHz, such as televisions, air conditioners and home theater. The IR receiver requires a digital input pin and is connected to the pin on the Arduino D2, and the A4 pin layout of Particle.
  • Temperature sensor
The temperature sensor belongs to the series MCP9700 / 9701 and converts the temperature to analog voltage. A key advantage of this series of thermistors is the resistance to the parasitic capacitance and the ability to drive large capacitive loads. The output pin of the IC is connected to the A1 and A4 Arduino Particle sizes.
  • Light sensor
The ZERYNTH Shield integrates a photoresistor, also known as light dependent resistors (LDRs). The LDR are variable resistors and low cost where the resistance changes depending on the amount of light that strikes its surface. In dark resistance it is high; in bright environments the resistance is low. They can be used to respond to events such as the transition from day to night (and vice versa), for home automation applications and gardening, and are often used to control street lighting. The circuit is a simple voltage divider that allows quite accurate readings of the resistance of the photoresistor. The resistance opposed to the LDR has been set to 20k because the LDR chosen has a resistance that varies from 12k to 36k ohms. The sensor is connected to A5 on Arduino and A0 formats Particle.
  • Acoustic transducer
A small electret microphone amplifier with a gain of about 200 times is used to allow detection of voices, ambient sounds and noises like. The circuit is implemented based on a simple amplification stage followed by a buffer. The output of the microphone is connected to the Arduino pin A3 and A2 of the Particle.
  • Capacitive Touch

The ZERYNTH Shield integrates a capacitive touch sensor based on the chip AT42QT1010, an integrated component used to convert any surface into a capacitive button. The chip handles the monitoring of a conductive zone and is activated when it is touched. Until a touch is detected (for example by a finger), the AT42QT1010 maintains the output signal at high level. When the touch is lost, the signal is brought to the low value. The sensor output is connected to pin D7 AT42QT1010 both on Arduino that about Particle. The pin of the touch can be connected to a metal surface by sensorizzare through the expansion connector (P1).


  • Piezo buzzer

This transducer mounted on the ZERYNTH Shield serves to generate beeps, tones and alarms. The buzzer is powered through line 5 V to avoid interference with the sensors. The buzzer is driven by the pins connected to the pin on Arduino and D8 on the A6 Particle.


  • LED IR emitter

An IR LED driven by a BJT is connected to pin D6 Arduino and to pin A5 on Particle. A wave PWM is used to create infrared pulses that can be received and decoded by common IR receivers.


  • LED Adafruit Neopixel
In ZERYNTH Shield it has been included also a dedicated port for connection of LED strips Neopixel of Adafruit. The power pin is connected to Vin of Particle and pin 5V Arduino. The pin to be used are (GND, Vin, LED control pin). The pin control for digital control of LED is connected to pin on Arduino D9 and D6 to pin on Particle. If the configuration includes more than 24 LEDs, in order to avoid damage to your card, you must use an external 5V power supply to power the LED.
Expansion Connector


It is a male connector 8 X 2 of which are available all pins Aux in a configuration compatible with the analog and digital modules Seedstudio Groove. The expansion connector also allows easy use of modules Phidgets and Thinkerkit, and also provides power lines 3.3V, 5V and GND. The expansion connector also allows you to expose the pin SPI but unfortunately this function, available in the Arduino and the core, is not available on the Photon Particle due to hardware limitations. ZERYNTH The shield also includes a port to use the I²C. The door has an order-pin compatible with the sensors and actuators I²C Groove (3.3, SCL, SDA, GND) that allows the use of these plug and play modules. I²C devices from other vendors can be used, making sure to make the proper connections.

ZERYNTH Shield Library


The ZERYNTH shield was developed to make life easier for developers of new intelligent objects. For this reason the ZERYNTH team developed a control library dedicated to ZERYNTH Shield. The Shield of ZERYNTH control library is released along with the ZERYNTH suites and includes various senior functions ready to be used. Some examples: the average of the sensor signals and data filtering systems originating from it. There are also a host of intelligent features such as the "smart motion detection" that allows to use the light sensor as a presence sensor or the "double-click" that allows detection of two close touch of a button through the capacitive sensor.
