If you are just a hobbyist, like me, making studies in electronics to come up with inventions (and have so much fun during this learning process) and want to have a good time at home, then you may be interested in watch these videos.In each (most) you will find examples of applications in Arduino using Proteus to simulate.The videos are separated by chips' categories: counters, decoders, encoders, multiplexers, shift registers, op amp, comparator, magnitude comparator, schmitt trigger, amplifiers and flip-flops. I endeavored much effort to bring the essentials. I searched on the internet applications that serve as presentation of each chip, its purpose and its potential. I was careful to add closed captioning in videos in case you do not understand my English, although I strive to hit. You will also find the file to run on Proteus 8 and PDF for you to proto. Feel comfortable to comment, make suggestions and critique the videos.We are all hobbyists!! Have fun with electronics!!
