The Transistor

 
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 https://www.thingz.co/store/create:
 
If button is pressed, LED 1 lights up, LED 2 lights up and digit display shows number 0.
