# Assembly ## Introduction --- Hello, now it's time for us to do the assembly. We're going to assemble the [Ring:bit](https://shop.elecfreaks.com/products/elecfreaks-pico-ed-ring-bit-v2-car-kit-with-pico-ed-board?_pos=2&_sid=18032a345&_ss=r) smart car step by step in this wiki. Let's get started with your nimple hands! ## [Ring:bit](https://shop.elecfreaks.com/products/elecfreaks-pico-ed-ring-bit-v2-car-kit-with-pico-ed-board?_pos=2&_sid=18032a345&_ss=r) Car V2 Components List --- First of all, these two pictures below are the parts diagram of [Ring:bit](https://shop.elecfreaks.com/products/elecfreaks-pico-ed-ring-bit-v2-car-kit-with-pico-ed-board?_pos=2&_sid=18032a345&_ss=r) smart car, you can first familiarize yourself with the parts style and name, and then check if your kit has all the parts inside. ![](./images/assembly01.png) ![](./images/assembly02.png) ## Assembly Step --- ### Step-1 Fisrt, use the tapping screw to fix the servo to the side board.(as below pictures) ![](./images/assembly03.png) Then, use the screw to fix the wheel to the servo.(as below pictures) ![](./images/assembly04.png) ### Step-2 Use the rivet to install the castor wheel on the chassis. ![](./images/assembly05.png) ### Step-3 Assemble the front board, the back board and the base board to the side board as below picture. ![](./images/assembly06.png) ### Step-4 Use the binding post to fix all installed components. ![](./images/assembly07.png) ### Step-5 Use the screw to fix the [Ring:bit](https://shop.elecfreaks.com/products/elecfreaks-pico-ed-ring-bit-v2-car-kit-with-pico-ed-board?_pos=2&_sid=18032a345&_ss=r) to the micro:bit board. ![](./images/assembly08.png) ### Step-6 Connecting wire as below pictures, you can connect the pins as you wish but make sure the programming be consistent with the connectons. Note: No matter which connection you use, make sure the yellow line connects with the number pins(0/1/2). ![](./images/assembly09.png) ### Completed Fix the assembled [Ring:bit](https://shop.elecfreaks.com/products/elecfreaks-pico-ed-ring-bit-v2-car-kit-with-pico-ed-board?_pos=2&_sid=18032a345&_ss=r) to the front board. ![](./images/assembly10.png) Congratulations, with your great assembly skills and continued hard work, you have finally assembled the [Ring:bit](https://shop.elecfreaks.com/products/elecfreaks-pico-ed-ring-bit-v2-car-kit-with-pico-ed-board?_pos=2&_sid=18032a345&_ss=r) car. In the next lesson, let's experience a new journey together by writing code to drive the [Ring:bit](https://shop.elecfreaks.com/products/elecfreaks-pico-ed-ring-bit-v2-car-kit-with-pico-ed-board?_pos=2&_sid=18032a345&_ss=r) smart car.
