Want to pick up a new hobby? or interested in electronics and engineering? Well Arduino is a great solution for that! However they are quite costly but you can still create your own circuits for free using Tinkercad with your university account!
This will be a Step-by-Step tutorial on how to make simple circuits with Tinkercad's Arduino.
Step 1: Log into Tinkercad using your UAlbany email.
Step 2: Head over to the circuits tab and click "Create new Circuit"
Step 3: Rename your project and bring in a Arduino Uno R3
Step 4: Before you start, Some things you should know
Tinkercad has buttons + hotkeys you should know before starting.
Undo : Ctrl + Z
Redo : Ctrl + Y
Clicking on a component and Ctrl + C, will allow you to copy component
Ctrl + V pastes copied component
Step 5: Drag two LED bulbs, and a small breadboard
Some information for you to know: A bread board is (in this case) a solderless construction base to create a circuit or electronic.
An LED is a light emitting diode this will light up when connected correctly or later on the project will pulse at random intervals.
Step 6: Drag out two resistors and set their Ohms labeled : Ω (resistance) to 220
A resistor is an object that is designed to have resistance to the passage of electricity, the simulation of Tinkercad replicates how it would work in real life as well.
Step 7: Placement of objects and wires.
Now that you have the basics all on your work space, its time to combine them and add wires!
Make sure the resistors are connected below the LED's cathode (as labeled on the led)
Wires must be connected specifically to GND (ground) and the negative part on the breadboard and 5V (5 Volts) to the positive part of the breadboard
A tip about wires: you can make your wires look neater and more realistic if you click and drag them, as seen in the gif below
Remember to color code the wires! Red means positive and Black means negative (in a breadboard sense).
Step 8: Code the LED's To light up either using Tinkercads block or using Arduinos C++ capabilities.
This is the code that is given for following the code block tutorial if you hit the above dropdown and change it to text or blocks + text.
WARNING: If you click the drop down menu to just "text" you will not be able to revert back to blocks and this can damper beginners from proceeding with a project.
Step 9: LED Light up + serial monitor text
Below is some information about the serial monitor + some tests.
Now lets go to our last advanced step where we will create LEDS to light up based on the serial monitor text
