An initiative, named 'Road to 4IR' was taken by EMK Center -Maker Lab for training 30x4= 120 students (60 Male & 60 Female) in 04 cohorts in the technology of the 4th Industrial Revolution. This session was the 3rd of total of 04 sessions- where the initially trained participants will be further trained under the supervision of expert mentors to materialize the training by planning, designing, and making a scientifically proven concept paper/ robot/solution. In this Session-03, the students were introduced to basic electronics components including Arduino, Breadboard, Jumper Wires, Buzzer, LCDD Display, Ultrasonic Sensor, IR Sensor, LM35 Temperature Sensor and other passive components. They were also trained on how to search for a datasheet of a specific components and search for relevant spec and characteristics. Also, in the session- they were taught how to start and complete making project/solution at the end of this session. Moreover, the students were introduced to 'Tinknercad'-where they can make project simulations, without buying the products physically. The 4th and last session of the 2nd phase will close the continuation of the 3rd session and after that, the team will be assigned with the mentors on different expertise. The program was held on 24th August, 2021. Both 1st & 2nd Cohort attended from 7:15 pm - 9:30 pm. Both sessions were taken by Redwan Ferdous, Mentor of Embedded system of MakerLab, EMK Center.

18. TinkerCAD
• “From mind to design in minutes”
• Tinkercad is a free, easy-to-use app for 3D design, electronics, and
coding. It's used by teachers, kids, hobbyists, and designers to
imagine, design, and make anything!
• It’s a web based simulator
• Basically we will focus on Electronics Project Development, at very
initial stage, for newbies and hobbyists.
• But this online simulator can also be used in different 3D modeling,
designing and prototyping.

19. TinkerCAD
• Tinkercad is saying about themselves:
“Tinkercad is a free online collection of software tools that help people all over
the world think, create and make. We’re the ideal introduction to Autodesk, the
leader in 3D design, engineering and entertainment software.”
• Using Tinkercad, creating something is called ‘Tinkering’!
• There are 03 major platforms to work at Tinkedcad:
• 3D Design
• Electronics
• Codeblocks

23. Projects
• Using Tinkedcad, we will do total 03 basic projects:
• LED Blinking and Pre-set Projects of Tinkercad
• Gas Sensor +LED
• Ultrasonic Sensor+ LCD
• Neopixel Strip Light (EMK!)- Bonus!
• Through these 03 projects, we will learn schematic design, coding and
simulation.
