Dance Dance Roverbot! Build a Light Activated Dancing Snap Circuits Programmable Robot.

Step 10 Build a Circuit for the Light Activated Roverbot

In this step you'll build the circuit for the rover bot. You'll recognize the power regulator block (B5), the PICAXE (U14), the H-bridge block (U8, labeled "Motor Control"), and the snaps for the rear of the rover. You'll also notice some new components. In addition to the snap conductors and the jumer wires, you will notice 2 1K ohm resistors, a 100 ohm resistor, and a photo resistor. The photo resistor is the sensory input (like a primitive eye that is sensitive to light) for the PICAXE brain. 

The Snap Circuits parts needed for this step:

1 10 X 10 Plastic Base Grid
1 Rover
1  9 volt Battery Block B5
1  Motor Control IC U8
1 8 Pin Socket U14 With PICAXE 08m Installed
1 100K Ohm Rsistor R5
2 1K Ohm Resistors R2
1 Photo Resistor RP
1 Slide Switch S1
1  USB Programming Cable
2 Single Snaps
15 Two Snap Conductors
1 Three Snap Conductor
1 Four Snap Conductor
1 Six Snap Conductor
1 Seven Snap Conductor
1 Orange Jumper Wire
1  White Jumper Wire
1 Green Jumper Wire
1 Yellow Jumper Wire
1 Purple Jumper Wire
1 Gray Jumper Wire
