  • Page 18 Project 4 Alternating Lights Build this circuit. Load sketch Alternating_Lights into Snapino using the programming instructions in project 3. Arduino controls the two Snap Circuits LEDs (red and ® green), and alternates turning them on and off. Programming Note: This sketch uses the command (int is short for integer) to assign a constant value that will be used within the sketch.
  • Page 19 Project 5 Stoplight Build this circuit. Load sketch Stoplight into Snapino using the programming instructions in project 3. Snapino controls the three Snap Circuits LEDs (green, yellow, and ® red), and turns them on and off like a stoplight. The yellow light is only on for half as long, just like a normal stoplight.
  • Page 20 Project 6 Button Build this circuit. Load sketch Button into Snapino using the programming instructions in project 3. The red LED (D1) should be on; push the press switch (S2) to turn it off. Swap the locations of the press switch and 10KW resistor (R4).
  • Page 21 Project 7 Bicolor Light Build the circuit and load sketch Bicolor_Light into Snapino using the programming instructions in project 3.

  • Page 27 Project 16 Varying LED Brightness Build circuit load sketch Programming Note: Varying_LED_Brightness into Snapino using This sketch uses a counter to increase the brightness of the LEDs. Once the LED nears full the programming instructions in project 3. The brightness then the counter decreases to make three LEDs (D1, D2, & D10) continuously vary in the LEDs dimmer.
  • Page 28 Project 17 Light Controlled LED Build the circuit and load sketch Light_Controlled_LED into Snapino using the programming instructions in project 3. Vary the brightness of light on the phototransistor (Q4) to change the brightness of the red LED (D1). The red LED gets brighter as the phototransistor gets darker. The circuit acts as a night light, making the red LED brighter as the room gets darker.
  • Page 29 Project 18 LED Brightness Button Build the circuit and load sketch LED_Brightness_Button into Snapino using the programming instructions in project 3. Push the press switch (S2) repeatedly; the red LED (D1) gets brighter each time. After the red LED reaches full brightness then it resets and starts over. Programming Note: The red LED brightness is set using the analogWrite()
  • Page 30 Project 19 Sloppy Switches Build the circuit and load sketch Sloppy Switches into Snapino using the programming instructions in project 3. Slowly push the press switch (S2) many times, watching the red LED (D1) as you do. Usually the LED will turn on or off when you push the switch, but sometimes it will stay the same.
