Arduino 2WD Smart Robot Car Kit

You’ll need the following:

1 x Arduino Sensor Shield v5.0 - Use a needle nose plier if pins need alignment

1 x L298N Dual H-Bridge Motor Driver - Connected to both DC

1 x Arduino Uno board - DO NOT plug in USB & DC at the same time

1 x 40 Pin Breakable Headers - Not needed for the kit

4 x Servo Mounting Brackets - You’ll need this for fastening the servo

3 x Servo beams - You’ll need this for mounting the servo

1 x Servo Motor (SG90) - You’re going to mount HC-SR04 on this

1 x Arduino USB Cable - To program your Arduino board

1 x HC-SR04 Sensor - Ultrasonic Ranging Detector

2 x DC Motors

2 x 2.51” Rubber wheels - High Grip Rubber Tires

1 x Acrylic Robot Chassis - That’s covered with adhesive protection

2 x Speed encoders - Not needed for the kit

1 x DC 1.5V Battery Holder - Will be connected to the switch

4 x Motor Blocks - To connect DC Motors to the chassis

2 x Stranded 24 AWG Wire Sets - To connect switch and other components

1 x ON/OFF Switch - Kill Switch

1 x Metal ball Caster - The third wheel

1 x Female DC Power Adapter - To be connected to the Arduino board

1 x M3 Screw, Spacer and Nut Set

1 x Jumper Wire Set

1 x Untapped Spacer Set

Recommended Tools

1 x Needle Nose Plier

1 x Flush Wire Cutter

1 x Wire Stripper

1 x Screwdriver (+)

1 x Hammer

1 x Soldering Iron (Optional)

Heat Shrink (Optional)

Brass Sponge (Optional)
