The iHacklab Tester

by J.B. Wylzan

Project 8:  Led Bar Graph Tester:
This project shows how to make a tester with an leds bar graph indicator. The device checks wire continuity, busted resistors, burned Leds and Arduino Board malfunctions.

9 LEDs
9 resistors 
connecting wires
Arduino R3 UNO board

Code # 8:
   iHacklab Tester
   powered by Arduino
   sketched by J.B. Wylzan
  modified by Lawsinium

  Tests continuity of wires, Leds, resistors, and Arduino board.
  This example code is public domain.

 // Setup pins 4 to 12
void setup() 
  pinMode(4, OUTPUT);
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);
  pinMode(7, OUTPUT);
  pinMode(8, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
  pinMode(11, OUTPUT);
  pinMode(12, OUTPUT);

The code is incomplete. You will finish the program by using the knowledge you've learned in our previous projects. The challenge can be accomplished using electronic components having varying values. 

Actual Layout:

1. Build the model as shown above
2. Run the Arduino Interface
3. Select File > New
4. Copy Code #8 above
5. Paste Code #8
6. Click File > Save
7. Click Verify
8. Click Upload
9. The 9 leds will turn On from one to nine gradually depending on what the tester senses.
