Theremino System

introduzione

Theremino is a different system from Arduino, it can be complementary to it. Even this little board with its software opens up new possibilities for teaching.

On this page some notes. We attempt to enclose all in a single page to show the simplicity of this new system.
Please refer to the official website for further information and more details www.theremino.com

how to begin

You can buy only the Theremino Master (19.90 euro here: www.ideegeniali.it)
Download the main app* HAL
Connect the board to the PC by cable.
If you need of a bigger number of pins you can add other boards, as you want.
If you need you can add a lot of apps or build your own app.

*All Theremino apps are portable application. A portable standalone application does not leave its files or settings on the host computer

fast actions:

led's games

You connect one or more leds on the pin (without resistors)
Select Pin type: Pwm_8
Into the cell "value" you can change values.
*pressing the left button of the mouse and moving it up and down, you can change the value.
You can use, if you want, the nice app Theremino_SlotViewer or Theremino_Rgb

servos

connect the servos on pins.
Select Pin type: Servo_16
You can move the servos changing its cell value. So you can animate a little robot
You can use, if you want, the app Theremino_Arm

reading from sensors

You connect your sensor (light, temperature, umidity... )
If it has 3 pins Signal - +5V - GND

If it has 2 pins Signal - GND
Select Pin type: Res_16
In HAL double click on the row of pin. You'll have a graphical debugging (oscilloscope).

HAL

here the download: --> link
--> help

few things to know:

HAL is essential and should remain lit, you can minimize it, but it must remain in operation.
Click on Recognize after the connection of Theremino
You'll see the rows of the pins (6 if you have only the board Theremino Master).
Click on each row and select the type of the pin that you want (see the table)

→ uses 8 bits for the transmission of data if you don't need of high precision
→ types with pullup, its name ends with "_pu", allow to connect a device without pullup resistors.
→ To facilitate connections and modular system Theremino transforms all raw values ??in a "range" standard from 0 to 1000

setup	void setup(){ pinMode(1,INPUT); }	the setup is in HAL
main loop	void loop(){ ... }	static void EseguiConPause() { ... }	Sub PausableExecution() ... End Sub
pause	delay(200);	PausaMS(200);	PausaMS(200)
conditional	if(x>125) { ... }		if x>125 ... End if
repeat a loop	for(int i=1;i<=3;i++){ ... }		for i1 as int32=1 to 10 ... Next
variables	int x=100;		dim x as Integer=100
variables	float x=100.23;		dim x as single=100.23

In "Arm properties" set lenghts of four links LenX, LenY e LenZ. In cells "Delta" set the angles of the links.

Arduino

sonorous tomatoes

as the Makey Makey

you connect cables to Signal. Then you connect bananas, apples, glasses of water, metallic objects...
Select Pin type: Cap_8
set "Proportional area" to 0.
set "Min variation" a 100. Look at HAL the values of the column "value". 1000 is on, 0 is off. If you touch the apple and the value is still 0, set a smaller value (20 - 50). If happens that you are touching nothing but a value is 1000, set an higher value (150-200)
Use short wires. They have to not touch each other. Don't move them. If you move press again Recognize .
Using Theremino_KeyManager_V1.0 , you can assign to each pin a key of Pc's keyboard. Then you can use any app you want.
To play music you can use this app . Set your pins as: Q - W - E - R - T - Y

Arduino and Theremino

work in progress

Theremino System

Theremino is an Open Source system for teaching and scientific applications, which allows the PC to interface with the outside world. There are many examples, from the simple (turn on an LED), to complex scientific applications (gamma spectrometry). Can be measured, with cheap sensors, each type of physical quantity, temperature, radiation, magnetic fields to chemical compounds. And you can control servos, motors, LEDs and lamps, ovens, solenoid valves, relays, process controls, robots, etc..
Unlike similar systems (eg Arduino), the system works just turned on and does not require programming the firmware.
