DESIGNING A LIGHT WITH A SWITCH

You can create a simple light circuit with a switch by opening a new circuit window in Tinkercad
and adding components like a 9V battery, switch and light bulb.

Choose the appropriate resistor To design a light with a switch, follow the given steps:
value to limit the current and Step 1 Click on the Project Name and rename your project (LIGHT WITH SWITCH).
protect your components.
Step 2 Connect the positive terminal of the 9V battery to the left leg of the switch using a
red wire.
Step 3 Connect this left leg of the switch to one leg of the bulb using a green wire.

CREATING A SERIES CIRCUIT USING TINKERCAD Step 4 Connect the negative terminal of the 9V battery to the middle leg of the switch using
a black wire.
To build a series circuit, use LEDs, a resistor and a battery to create a series connection. To begin, Step 5 Connect the free leg of the switch to the free leg of the bulb using an orange wire.
open a new circuit window in Tinkercad and start building your circuit by placing the following Step 6 Click on the Start Simulation button to test the circuit.
components: a 9V battery, two LEDs and a resistor.

To create a series circuit, follow the given steps:
A typical value for LED

Step 5 Connect the anode of the second LED to the positive terminal of the 9V battery.

Step 6 Click on Start Simulation to test the circuit.
Once you turn on the switch, the circuit will be complete and the bulb will

A microcontroller is a small, programmable chip that functions as the
brain of an electronic device. It contains a processor, memory and pins
that allow it to connect to other components in a circuit. By following
instructions written in code, it can control various things, such as lights,

of many electronics projects. Microcontrollers are used in everyday
objects like robots, smart devices and home appliances to help them
work automatically, making tasks easier and more efficient.
