I have been messing with electronics since 1964, essentially a 35 year career. I am presently a retired 75 year old duly registered 'Ol Fart'. My last hobby electronics was a basement full of HO scale model railroad. As part of lifestyle downsizing I dismantled the model railroad and converted the basement space to a living area. To an interest in electronics I chose to make the Arduino/Robotics a replacement hobby as this, as a hobby, takes far less time, space and money to maintain. I mostly enjoy the Arduino coding aspect part of the hobby. I have a small dual motor tracked chassis and an Arduino UNO that I use as a test bed for Arduino coding experimentation. I have been following DroneBot on YouTube and chose to join this forum to gather further insight into Arduino applications. ?
