TT Yellow Gear Motor (Arduino smart car)
by Generic
SKU: PSA-CMP-TT-MOTOR
No reviews yetTypical India street price
₹40–₹90
The yellow plastic-gear motor on almost every Indian 2WD/4WD kit.
Interface: DC 2-wire
Always drive through an H-bridge (L298N/TB6612), never from a GPIO pin.
Connect motor terminals to driver OUT; driver IN/PWM to MCU.

Concept
Low-cost DC motor + plastic gearbox + D-shaft for wheels.
A little theory
Stall ~1 A. Plastic gears strip under stall — teach current limits. In the classroom, treat TT Yellow Gear Motor (Arduino smart car) as a beginner part using DC 2-wire. Typical India street price is about ₹40–₹90. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
How it works in a project
L298N/TB6612; match left/right polarity so both go forward.
Classroom & project use
- 2WD/4WD cars
- Conveyor demo
- Motors & Servos classroom demo
Buying in India
Precautions
- Share a common GND with the microcontroller
- Verify polarity and voltage before powering the circuit
