Line Following Robot with PID project uses IR Sensors, Microcontroller and Motors to follow a line path on the floor. PID is a type of error-reduction algorithm implemented in such robots to reduce their errors and improve accuracy and precision. ## Project Details This project is built under Hack Club's Blueprint Program. Custom shape PCB is be used as chassis for the car. PCB covers all components routing alongwith components mounting and soldering. This reduces the wires and improve the project's appearance. Moreover, it reduces the weight due to separate chassis making it more efficient.…

Linefollowingrobot: common questions

What microcontroller does the Linefollowingrobot use?

The Linefollowingrobot is built around the ESP32-S3-DEVKITC-1-N8R8, from the ESP32 family.

How big is the Linefollowingrobot PCB?

The Linefollowingrobot measures 130.5 × 169.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Linefollowingrobot?

11 components, from 10 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Linefollowingrobot design files?

From the msafeerhassan/linefollowingrobot repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Linefollowingrobot design in my own project?

The repository has no license, so all rights stay with msafeerhassan. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Linefollowingrobot without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
