Gravitational force Mater using Arduino
All parts needed if you wish to make it standalone:
1 -Circuit Board
1- 28 Pin socket
5- RGB LEDs (Mine were common anode)
5-Resistors 1K ohm
5-Resistors 500 ohm
1- 16MHZ Resonator
1- 104 cap
1- 10uf cap
1- 3.3v rg. (LM1117T)
1- ribbon cable
1- header connectors
1- 9v Batt. Connector
Here is the picture of the wiring needed for a breadboard setup.
The orange wires hook to the 500 ohm resistors and then hook to the RED LED cathode.
The Green wires hook to 1kohm resistor the hook to the GREEN LED cathode.
The common anode is hooked to +3.3v
X axis output of ADXL335 goes to PIN 0 (Picture is slightly different)
+3.3v and Gnd are hooked to power and ground pins of ADXL335
The AREF pin on the Arduino is hooked to +3.3v
“digitalWrite(led1G, HIGH);” turns the LEDs to OFF not ON.
If you use common cathode you will need to change the code.
If you wish to change the pin number just change the beginning of the code:
int led1G = 2;
int led1R = 3;
int led2G = 4;
int led2R = 5;
int led3G = 6;
int led3R = 7;
int led4G = 8;
int led4R = 9;
int led5G = 10;
int led5R = 11;
int X_AXIS = 0;
Here is an image of the circuit board I designed using expresspcb I also attached the PCB file and a parts list for doing this. You can make this board or leave all of you components on the arduino and try to fit it all in project box.
