Simple circuits made using Tinker cad

 Simple circuits made using Tinker cad:

LEDs connected in series:

Here we connected 3 different LEDs in series and a push button is used to turn on the LEDs powered by a 9v battery.

LEDs connected in parallel:

Here we connected 3 different LEDs in parallel and a push button is used to turn on the LEDs powered by a 9v battery.

Led connected to a coin cell battery:

Here we connected 3 different LEDs in series and a push button is used to turn on the LEDs powered by a 9v battery.

Hobby gear motor a 9v battery:

Here we connected a hobby gear motor to a 9v battery.

PIR sensor motion detection circuit

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications.Here we connected 3 1.5v batteries to a PIR sensor and an LED.When any object or person is detected the LED will glow.

Vibration motor to a coin cell battery

Here the vibration motor is powered by a coin cell battery.

Temperature Sensor circuit:

LM35 temperature sensor is connected to 2 1.5v AA batteries and a multimeter.We can see how the change in temperature affects the voltage values.

Tilt sensor circuit:

Tilt sensor is connected to 2 1.5v AA batteries and an LED.We can see the tilting of an object is detected and the Led is lit.

Multiple led and RGB Circuit

The above circuit shows multiple Leds and  RGB light connected to a 9v battery and push buttons.

NPN circuit to light an led

The above circuit shows how an NPN transistor acts as a switch and control an led with the help of a switch.
