What is Kniwwelino?
The Kniwwelino is a electronic chip programmable via a playful and easy-to-use interface. Once connected to different accessories, it allows to carry out scientific, mathematical or recreational projects. To work, the Kniwwelino only needs a connection to an external power supply via a USB cable and an internet connection (WiFi). External power can be of three types:
A POWER BANK
A COMPUTER
A WALL SOCKET
The accessories that can be connected to the Kniwwelino are varied: sensors (measurements oftemperature, distance, magnetism, …), motor (movement creation), buzzer (sound emission), … Thanks to the variety of these, it is possible to carry out a lot of activities. In addition, the Kniwwelino has a matrix of bright LEDs to display messages, colors or symbols.
To connect to these different accessories, the Kniwwelino has 7 connection ports:
- 2 above: GND and 3.3 V, and
- 5 below: AD (A0), D7, D6, D5 and D0.
The two upper ports are used to supply electrical power to the accessories with a current of 3.3 Volts. The five lower ports give and/or collect accessory information (such as a measure). The grey arrow pointing down indicates the USB port.
Finally, the Kniwwelino has two buttons: A and B. These allow different actions to be carried out depending on the programme carried out.
To connect the accessories to the Kniwwelino, nothing could be simpler than crocodile claws! Designed to open with a slight pressure, they connect easily to the different ports. The photo on the right depicts a circuit made with the Kniwwelino and a distance sensor.
In a nutshell
Via a programming interface, the information is sent by WiFi to the Kniwwelino which allows accessories (sensors, buzzer, servomotors, …) to operate and thus carry out great activities!
