Encoder and servo 6

In this activity you’ll learn how to control a servomotor with an encoder. A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to an analog or digital signal.

Seven segment display 4

Seven segment displayShow me something! What are we going to do? In this activity you’ll learn how to show something on a seven segment display. In order to make it easier to use the display, we’ll use a library.  Materials We’ll use components from Elecfreaks kit that can be found […]


Temp and hum sensor 3

In this activity you’ll read the ambient temperature and humidity with a DHT11 sensor brick. In order to use the sensor, you’ll need a library. Libraries provide extra functionality for use in sketches, e.g. working with hardware or manipulating data.

PIR sensor 3

In this activity you’ll learn how the PIR sensors work. A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. We’ll use it to turn a led on or off.


Buzzer! 5

In this activity you’ll play a melody with the help of a passive buzzer and an Arduino board.

LDR sensor 5

In this activity you’ll write some code that turn a led on o off when ambient light is low. We will achieve this thanks to a LDR sensor brick or LDR circuit.

Hello world with Arduino: Blink 1

In this activity you’ll program your first Arduino code.
This code turns a LED on for a second, then off for one second, repeatedly. You can find this code under Arduino IDE -> File ->Examples -> Basics ->Blink
You don’t need any extra components as it uses a LED connected to pin13 that most Arduino boards have.


The Railroad Hand Car 13

Makit proudly presents… The Railroad Hand Car! It is scale model of a hand car that works with a micro motor and a switch to turn it on-off or change direction. It also has an optional driver and a wagon.

Electronics, 3D printing and mechanics: STEP CLOCK 1

I have been wanting to use some stepper motors to design a clock for a long time, and finally I could find some time and IT IS HERE!
It uses two steppers to move hour and minute hands independently with 3D printed concentric shafts, while one Arduino compatible board controls everything.
