FAQ’s
What’s the difference between to the Raspberry Pi 3b+ and the Raspberry Pi 4 Model B?
Raspberry pi 4 is the newest model of the raspberry pi series. Raspberry Pi 4 takes Pi to another level, with a performance that’s good enough to use in a pinch as a desktop PC, plus the ability to output 4K video at 60 Hz or power dual monitors. New features include:
- A faster processor and GPU,
- More and faster RAM,
- The addition of USB 3 ports,
- Dual Micro HDMI ports instead of a single HDMI connection and support for 4K output,
- A higher bus speed that enables USB 3 support also allows the on-board Ethernet port to support true Gigabit connections (125 MB/s)

We found a nice tutorial that covers most of the sensors here
We found this article explaining what the sensors are used for: http://www.instructables.com/id/Arduino-37-in-1-Sensors-Kit-Explained/?ALLSTEPS
This kit introduces quite a few electronic principles, its fun and not difficult to build. This is a self-build DIY smart tracking robot car kit. It is an introductory electronic kit designed to help kids, electronic enthusiasts, and novices learn about basic electronic knowledge like soldering and simple circuits(photoelectric sensor circuit, voltage comparator, motor driving,ir sensors etc.) The smart kit is designed based on the principle of infrared sensor and light reflectivity difference when the light emitting on the white and black items
The assembly steps:
Step 1: Welding circuit
Soldering part is simpler, welding sequence according to the principle of component level from low to high, the first welding eight resistance, is important to use multimeter to confirm resistance is correct, D4, D5 R13 R14 can temporarily not welding, integrated circuit chips can temporarily not inserted
Step 2: Mechanical assembly
The red line is connected to the 3V positive power supply, the yellow line grounding, excess wire an be used for motor wire.
Step 3: The installation of a photoelectric circuit
Photosensitive resistance and light-emitting diodes (note polarity) is reverse-mounted on the PCB, and the ground distance is about 5 mm, both photosensitive resistance and light-emitting diodes are 5 mm distance. Finally, you can power test.
Step 4: Vehicle debugging
The right direction is along the universal wheel direction, if you press and hold the left photoresistor, the wheels on the right side of the car should be rotated. Press and hold the right photoresistor, the wheels on the left side of the car should be rotated, if the car driving back, can also exchange the wiring of two motors, if the one side normal and the other side back up, as long as you can swap wiring of back side.
Note: We don't supply any manuals please note this before you buy it.
