In this tough time when whole nation is fighting from this pandemic and where social distancing is must so i have come with handmade sensor bell system. In INDIA for every 1 kilometres there is one temple as our nation is full of culture and devotes so i thought of this project as everyone after entering temple they touch bell as in this pandemic is not correct so had to think on it.

Supplies

IR Sensor

TIP32C PNP Transistor

1k Resistor

12v motor

USB cable

Temple bell

Acrylic sheets

Wires

Wheel

Screws

To start this project you need all the above materials

Step 1: Connection

As the above connection shown connect the wires from

IR sensor positive terminal - transistor E - positive terminal of USB cable

IR sensor negative terminal - DC Motor +ve - transistor C - DC Motor - negative terminal of USB cable

Output of IR sensor - 1k resistor - transistor B

Step 2: Hardware

Pick up the acrylic sheet and cut some of the strips (5) and one in the shape of circle and some drill as shown and please watch video carefully and observe and cut the acrylic sheet where ever required ,later assemble everything together and join as in video Drill properly as there should not be any disturbance or friction in movement.
