The Arduino tinker kit contains the following components (datasheet links open in external sites):

• 1 x solderless breadboard
  Does what it says on the tin: use jumper wires to create connections without soldering.
• 1 x Arduino equivalent board
  (e.g. Redboard Schematic | Graphical Datasheet)
• 1 x Battery holder - 4xAA to barrel jack connector
• 1 x micro or mini USB cable (depending on the included board)
• 8 x 120 ohm 0.5 watt metal film resistor
• 20 x 330 ohm 1/4 watt PTH resistor
• 20 x 10K ohm 1/4 watt PTH resistor
• 10 x male/male jumper wires
• 10 x female/male jumper wires
• 10 x female/female jumper wires
• 1 x triple axis accelerometer breakout (Datasheet)              
• 1 x line tracking sensor (Datasheet)   
• 2 x hobby gearmotor 140 RPM (Datasheet)
• 1 x 3.5 mm SPST micro tactile switch button
• 4 x 12 mm tactile switch buttons
• 1 x 7 segment display
• 2 x sensitive SW-520D ball switch
• 1 x trimpot 10k with knob (Datasheet)
• 2 x buzzer 5V
• 1 x H-bridge motor driver 1A (Datasheet)
