Arduino Nano as Attiny 85 programmer and 5 LED POV

Arduino Nano as Attiny 85 programmer and 5 LED POV 


Arduino modules/boards are not cheap and for simple projects like my Led Tree. we can use cheaper and more power efficient micro controllers like attiny85. There are many instructables on this topic, but bit old. I hope to share the latest information on how to setup ardunio Nano as simple ATttiny85 programmer


Step 1: What do we Need ?

The circuit is simple

  1. Programmer
    1. Ardunio Nano
    2. 10uF capacitor
    3. Attiny85
    4. few wires
    5. PCB

  1. POV
    1. 5 LEDs ( GREEN or Amber) ( Donot use Red)
    2. 8 pin IC holder
    3. 3V Battery
    4. Switch
Software
  1. Arduino IDE 1.6.4
  2. ​ATtiny Board files
Ref this url to setup the Arduino IDE High-Low Tech good instructions​

Step 2 : ​Build It and Code for POV





These are simple circuits to build
Once done Test it using blink sketch in the Arduino IDE examples
I have attached my sketch for POV

Step 3 : Lessons

  1. ​Do not Use Red LED, It is too bright and does not create good POV
  2. Reduce brightness / limiting current using a 100 ohm resister between all Cathodes and Ground. One is enough 
Where can you use this?
I used it on my son's bicycle and attached it to spoke using some cable ties. Looks nice in dark ( No clear photo because of RED LED)
