“In this instructable we’ll use the concept, reflection of infrared radiation to built a circuit which can detect the difference between black and white coloured surface. That might not sound interesting but later we can use that circuit to build a robot which will follow a black line, and the best part is, the whole build is purely based on electronics and no programming or coding is required! If you are getting started with electronics or getting a concept of science into a project this would be a great place to start. So, grab the components mentioned below and get started with the instructable.
hese are the list of products which can help you do this project with ease
IR LED Pairs
BO motors & Wheels
Caster wheel (alternative)
Lithium Battery with charger”
