Review on 🚗 VKmaker Smart Robot Car Chassis Kit with Speed Encoder, Ultrasonic Module, and Battery Box - New Avoidance Tracking Motor System 2WD. Includes Tutorial CD. by Glen Needham

It comes with all listed parts and instructions on DVD+R that you absolutely need. There is an 18 minute tutorial video that is very helpful. You need to extract .rar archive with WinRAR or Archive on Mac then you will have .mp4 video file. Although I have 4 years of experience with Arduino and others, I think others with less experience should be able to complete the project. Assembling the hardware is the easy and fun part. Since they upgraded the kit to a 6 battery holder (the manual uses a 4 battery holder) you will need to drill a 1/8" hole. However, although the motors have soldered leads (good) and the switch is also soldered (unlike in the video) you still need to solder two wires together, the switch's red wire to the battery's red wire. As someone else pointed out, there is an error in the instructions: the red motor driver board (L298N controller) IN1, IN2, IN3, IN4 must be connected to A0, A1, A2, A3 and NOT to A1, A2, A3, A4. A0-13 pins are identified as pins 14,15,16,17 in the code above. You will find it helpful to uncomment the AnalogWrite commands for pins 5 and 6. Check out the L298N controller instructions online, remove the jumpers near A1 and A4 and use AnalogWrite commands to control the speed of the motors. tyami (sofa, clothes). Help over 4 years ago for a rover without an ultrasonic detector. The code works but is poorly written. Combine these pieces with other fun things on Adafruit, Sparkfun, or Revain.
