| |
|
| |
|
| |
| Nie je celkom jasne, akoje to s tlacitkom, ale vo fore k produktu sa da najst takato informacia:
| |
|
| |
| For Maqueen version 4.0 or above, there is a line-key pushbutton. That's for calibrating the grayscale sensor.
| |
| If you find that the grayscale sensors are insensitive to the black line or not very accurate, you can recalibrate it by:
| |
|
| |
| 1. Turn on the power switch of the Maqueen and place on any black surface or if you have a grayscale map.
| |
| 2. Press the line-key button for about 1 second and you will see the two RGB lights in the front will flash.
| |
| 3. You can release the key and the calibration is done.

|
| |
| === Blinker ===
| |
|
| |
| Pre prácu so svetielkami na hornej hrane robota je potrebné nahrať knižnicu '''<code>Neopixel</code>'''
| |
|
| |
| Jednoduchý program pre blinker, funguje na tlačítka - stlačením ľavého tlačidla 🅰 sa zapne ľavá smerovka, pravým tlačidlom 🅱 sa zapne pravá. Stlačením oboch 🅰+🅱 sa blinker vypne.

| === Základné pohyby ===
| |
|
| |
| Výrobca, firma Kitronik poskytuje pre robota špeciálnu knižnicu. Niekedy sa volá iba '''<code>Kitronik</code>''', ale väčšinou ju nájdete pod názvom '''<code>Servo:Lite</code>'''
| |
|
| |
| Tento ukážkový program len pohýbe všetkými smermi a potom skončí.
