Target  Time!!

The Target project is a simple setup promising joy. Six targets are aligned on both sides of a 2x4, which are wired directly to a ioio programming board. The ioio will then act as a brain of this project while sending feedback to your mobile device. We have programmed the ioio to have multiple game-mode setups for lots of varieties in the game play.

Build Steps!!

1. Bread Boarding  -  2. Building The Stand  -  3. Wireing

1. Bread Boarding

Two Systems, Switch or Sound Activated Targes


The switch system is very simple but has mechanical issues.  We have had difficulty attaching two plates together in a way that allows the sensor button to be pressed when the outer plate is lightly hit.


The sound tragets are much more complicated to wire. They require an audio amplifier and power.  But on the mechanical side the sound targets have no moving parts making this a more reliable system.

2. Building Stand

This is our target board. A simple stand with a cross bar, we also call the cross piece the "arms". There will be two plates on both sides and under the three wooden blocks on top the arms. The three blocks are also going to be the RGB LED mounts. 

The arms are easily removeable, and go back on just as easy. They are put on with just two prongs, and holes on the bottom of the arms. The three wooden blocks are "biscuited" on. Which means it is just a thin wooden chip half in the blocks and arm bar, and wood glued in. 

The battery pack and rails for the PCB are hot glued on. 

Here is our target board with the six 

prototype targets, the gold plates. 

Teams will be on both sides

shooting at their respected 


We have switched from a button

 target to a speaker target.

This is our new design for the the target. Not fully finished yet.

3. Wireing

Here are our two components we have connected to our target board so far. Our battery pack, capable of holding 6 AA batteries thus supplying us with 9 Volts total. Also; we have two rails that allow our PC Board to slide on and off our target arm board in case it malfunctions. 

Here is a short video demonstating how to use the LED driver PCB implanting the  rails we installed

<-This is the new housing model for the wiring.

This is going to be the wire           ->

connections to outside of the mo-dual.
