I'm trying to build a 4-wheeled car that runs with one motor. No steering, just moving forward. It should be operated with remote control or two push buttons like this:
Button 1 = Makes the car just move (and stop) slowly forward continuously. Speed control with potentiometer.
Button 2 = Makes the car move very small amounts smoothly per pressing the button. Range should be controllable with potentiometer or similar.
Movements should be very smooth and slow, plus the whole device weights around 3kg so the motor should be strong enough. I'm a cnc machinery guy so the mechanical parts are piece of cake, but I just can't understand the electronics at all. I bought an Arduino Uno starter kit but got stucked very shortly after blinking leds lol.
I wish someone here could give me a "small" push into the right direction. What components I need, is it too hard for super newbie to build it without months of studying, and last backup question how much should I pay for someone to make me bolt on -electronics? Any help highly appreciated!!!
