“This is a tutorial on how to make a basic wall-avoiding robot. This project will require a few components and a bit of dedication and time. It would help if you have a small amount of knowledge on electronics but if you are a complete beginner, now is the time to learn! This is just how i learnt electronics; by making other peoples projects even though i had no idea how they were working at all. Gradually though i learnt small pieces that built up into actual knowledge i can apply to my own projects.
After you have completed this tutorial you will have assembled the circuit above and will (hopefully) have picked up some information on electronics. This may look daunting at first but breaking it up into easy to do steps makes it easily doable. Have fun!”
