Step 1: Materials and Tools
- Perforated circuit board
- Male and female headers
- 10uF capacitor
- Arduino Uno or Duemilanove (with an ATmega328, not an older board with an ATmega168!)
- ATtiny45 or 85
- Cutter knife
- Cutting mat
- Wire cutters and stripper
- Soldering iron
- Helping hand
Step 2: Cut Circuit Board to Shape
Cut a piece of perforated circuit board to size (see illustration) and file the edges.
Step 3: Solder Male Headers

Before continuing, make sure the board with headers fit into your Arduino.
Step 4: Disconnect Circuit Traces

Step 5: Solder Female Headers
Insert the female header pins and use an ATtiny chip as reference to make sure you get the spacing right. Then solder.
Step 6: Solder Circuit
Use jumper wire or cut wire to length and strip either end and start to populate the circuit board with wires to make the connections between the pins of the Arduino and the pins of the ATtiny. Use illustration and the following information for reference. Bend wires on bottom side to stop them falling out before you solder them.
Wiring your ISP connection
ATtiny ----- Arduino
Pin PB2 (SCK) ----- Pin 13
Pin PB1 (MISO) ----- Pin 12
Pin PB0 (MOSI) ----- Pin 11
Pin PB5 (Reset) ----- Pin 10
Plus (VCC) ----- +5V
Minus (GND) ----- GND
Arduino pins: RESET ----||---- GND

When you've finished making all the connections illustrated in the diagram (including the capacitor) then you are DONE!
