Hello all: I am brand new to the Arduino and electronics world. I am trying to create a device that will Move an led back and forth and have an Android app that will allow me to control the speed of the servo, lock both the forward and rear position so the servo can only go so far forward and so far backward but can be changed if I move the whole device. I’m thinking a slider for speed and a slider for forward and rear position. I bought the Arduino kit, books on Arduino, c++, and programming android and an a KEDSUM Upgraded Arduino Wireless Bluetooth Transceiver Module Slave + DuPont Cable from Amazon. However the only thing I can come up with so far is I think a servo is the type of motor I’m looking for. I need help, lol Bad… Any help will be greatly appreciated. Thank You
