Learning Electronics Smart Car Soldering Project DIY Kits Practice Soldering

Description: ☆ Welcome☆ to ☆ my ☆ shop ☆ Smart robot car is the most widely used in school for helping students to learn about the soldering project knowledge of mechanical structure, electronic basis skills, the principle of sensor, automatic control, soldering skill and so on.The operating principle is provided as product pictures shown and we provide electronic manual for you. It's much easier to assemble which is great for kids, beginners and hobbyist.As the light reflectivity is different when the light is emitting on the white and black items. It uses the photoresistor to tell if the smart car is on the right way or not. Smart tracking car can discriminate the direction automatically that it can run freely along the black tracking line.You can also use the 1.5~2.0 cm black electrical tape directly on the ground to design the complex runway. It would be even more fun!We provide paper English instruction come with the product. Product DescriptionDesign Your Runway - You can also use the 1.5~2.0 cm black electrical tape directly on the ground to design the complex runway. It would be even more fun! Line Following Robot Car KitHaveing Fun & LearningThere is a 16 mm wide black runway in the white field. Our tracking car can drive along the black runway automatically. No matter how the runway is bent, the car can be driven automatically.PrincipleThe reflectivity is different when the light source to the white objects and black objects.The light is reflected through the ground to the photoresistor. By detecting the Resistor of the photosensitive resistor can determine whether the car is driving in the white area.If the detection is black runway, then the car to change the direction of driving and motor will slow down.Soldering Tools1>.Soldering iron (<50 Watt)2>.Rosin core ("radio") solder3>.Wire cutters4>.Wire strippers5>.#1 Philips screwdriverMore tips about the DIY soldering that will directly affect the performance effect of the finished product as followed:1>.The package is DIY kit.It need finish install by user.2>.The soldering iron can't touch the components for a long time(1.0 second), otherwise it will damage the components.3>.Pay attention to the positive and negative of the components.4>.Strictly prohibit short circuit.5>.User must install the LED according to the specified rules.Otherwise some LED will not light.6>.Install complex components preferentially.7>.Make sure all components are in right direction and right place.8>.It is strongly recommended to read the installation manual before starting installation!!!9>.Please wear anti-static gloves or anti-static wristbands when installing electronic components.Shipping> We ship to worldwide.> Orders processed within 24-48 hours after payment verification.> We only ship to confirmed Paypal addresses.
