Turn a led on and off on pin 13, the first robotics program. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We add a forever loop. We declare the led on pin 13. We build the blink logic. When you finish, the app takes you straight to the next tutorial in the path. ...
Draw a label on the dashboard and write hello world in it. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We add a While loop, which repeats forever. On the dashboard we draw a label. We change the label text to hello world. When you finish, the app takes you straight to the next tutorial in the path. ...
Put hello world into a text variable and show it in a terminal. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We add a While loop, which repeats forever. We create a text variable called text with the value hello world. On the dashboard we draw a terminal and give it the variable text. When you finish, the app takes you straight to the next tutorial in the path. ...
Move a servo between two positions using the Servo block and a delay. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We create a servo called arm on pin 9. We add a While loop, which repeats forever. Inside the loop we drop the servo, which starts at position 90. Behind it we put a delay of 1000 milliseconds. We add another Servo block and send it to position 180. And another delay of 1000, to give it time to get there. When you finish, the app takes you straight to the next tutorial in the path. ...
Make a buzzer sound at a fixed frequency using the Frequency block. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We create a frequency called buzzer on pin 8. We add a While loop, which repeats forever. Inside the loop we drop the buzzer block. We ask for 880 hertz, which sounds higher. And make it sound for 250 milliseconds. Behind it a delay of 1000, so it sounds in pulses. When you finish, the app takes you straight to the next tutorial in the path. ...
Create a number variable, set it to a value and show it on a label. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We add a While loop, which repeats forever. We create a number variable called counter. Above the loop we set the variable to 100. On the dashboard we draw a label. We change the label text to counter. And we drag the variable counter onto the label. When you finish, the app takes you straight to the next tutorial in the path. ...
Turn a motor at a constant speed and stop it with a delay. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We create a motor called wheel on pins 2, 3 and 5. We add a While loop, which repeats forever. Inside the loop we set the motor to speed 100. Behind it a delay of 2000, so it spins for two seconds. Another motor block, now with speed 0, which stops it. And another delay of 2000, so the motor rests. When you finish, the app takes you straight to the next tutorial in the path. ...
Show the same variable on a label, a slider and a chart at the same time. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We add a While loop, which repeats forever. We create a number variable called value. On the dashboard we draw a label. We change the label text to value. We add a slider to the dashboard. And we add a chart to the dashboard. We drag the variable value onto the label. We drag it onto the slider too, so it can be moved by hand. And onto the chart, which draws how it changes. When you finish, the app takes you straight to the next tutorial in the path. ...
Light up a neopixel by mixing red, green and blue with the Neopixel block. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We create a neopixel called light, with 1 led, on pin 6. We add a While loop, which repeats forever. Inside the loop we drop the neopixel block. We turn its red up to 255. And the blue to 255 as well, so the light comes out purple. When you finish, the app takes you straight to the next tutorial in the path. ...
Two dashboard buttons that add and subtract one from the same variable. This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on. The steps We add a While loop, which repeats forever. We create a number variable called value. On the dashboard we draw a label and name it value. We add a button and name it Add. We add a second button and name it Subtract. On the dashboard canvas we build a Set with a sum inside. The sum is value plus 1. We drag that block onto the Add button and drop it on Press. We build another Set with a subtraction inside. This one is value minus 1. And we drop it on the Press of the Subtract button. Finally we drag the variable value onto the label. When you finish, the app takes you straight to the next tutorial in the path. ...
