Transistor (< transmitter+resistor): a switch which upon presentation of an electric signal allows or disallows the flow of electricity in a circuit
Comparison to a switch between a battery and a lamp
The field-effect transistor (FET)
It has three terminals: gate, source, and drain
Upon the presentation of an electric field to the gate, electricity flows between the source and the drain as shown at the video
Creating circuits at Maker Faire Paris 2017 with Thingz Electronics
Here is one of the circuits I created today (2017-06-11):
I put a LED and a button on a board (connected via USB to a computer) and then programmed on the Thingz electronics graphical interface https://www.thingz.co/store/create
(they say it is C++) this IF function (as shown in the image):
If the button is pressed, LED lights for 1 second.

Moving detector and buzzer circuit (alarm circuit)
Here is the second circuit I created today. I put a motion detector and a buzzer on a board (connected via USB to a computer) and then programmed on the Thingz electronics graphical interface
this IF function:
If the movement detector detects a continuation* of a movement, the buzzer sounds at 440 Hz.
*another option: initiation
Demonstration of a LED-button-digit display circuit by Thingz electronics
Two LED, a button and a digit display are placed on a board (connected via USB to a computer). The following IF function is programmed on the Thingz graphical interface
If button is pressed, LED 1 lights up, LED 2 lights up and digit display shows number 0.
