Mushroom Lamp Simulation in Tinkercad

When I have a project to make an art lamp object using LED-2835, I have some problems:

• In arranging the electric components like battery, resistor, LED, and switch.
• I didn't know how big resistance value to operate this lamp.

From those problems, I need to simulate and verify whether the system can run successfully or not, so I used Tinkercad Circuit to make a plan.

Finally, Tinkercad helped me a lot to solve my project.

In this project you are going to need

• Computer
• Internet connection
• Tinkercad account
• Calculator

Open your browser, and log in to your Tinkercad account. Then, choose Circuit on menu, and then click on the Create new circuit button.

Prepare your components on the workspace like Breadboard mini, resistors, LED, Battery 9v, and switch. You can browse all those components in the Search box.

Click the resistor component to add the value of resitance you need. So, in this step you can use electric equation for resistance.

I Made this project with Math to calculate resistance

R= (Vbatt - Vled) x series LED : Iled

Where:

• Vbatt is the battery voltage
• Vled is the LED voltage (you can know this information from datasheet)
• series LED is condition when you arrange the LED on series wiring (in this case, I used parallel wiring LED. So I assumed series numbers is a single LED).
• Iled is a the LED current (you can know this information from datasheet)

I used LED-2835 with characteristic 3.4v 16mA(0.016A) and Battery characteristic 9V

R= (9-3.4):0.016A=350 ohm

Thus, I added value of 350 ohm to the all of the resistors.

On LED variable you can change the name of the LED. but in this case I used number. You can choose the color of the LED in the Color box. But it should be noted that every LED color operate on different voltage. For example the LED color that I choose was white, operate on 3.4 volt.

LED is diode, it means that It allows the current to flow easily in one direction, but severely restricts current from flowing in the opposite direction. so you must know the positive and negative part of the LED. If the positive part of LED paired with negative part of the battery, the LED would not turn on. The LED have different shape of lead. The you can differentiate it by clicking the cursor of your computer on the lead of the LED (see the picture). Anode on LED is a positive part, thus you must joint the anode from the LED to positive part of the battery.

It shows that design for science about the flow of electron.

Switch is a tool to connect and disconnect electricity from the battery to the other components. There are three feet of the switch, and the middle feet is "common", meaning you have to paired this feet to the battery (positive or negative part, up to you). Then you need to paired the other feet from the switch to the component (see the picture).

In this step I paired the switch to the negative part of the battery and place the resistor before the positive part of the LED (anode). I connect the negative part from LED to the negative part of the battery. Based on the simulation, my mushroom lamp can run succesfully.
