I found the "4LED touch write block" at 100 yen shop .
I was tempted to make a ”Simon says”.

Step 1: 材料

・4LEDタッチライトブロック ・・・1個
・ATMEGA168P-20PU ・・・1個(または、ATMEGA328P-PU)
・ICソケット(26P) ・・・1個
・ユニバーサル基板 ・・・1枚
・タクトスイッチ ・・・4個
・3mmLED 好きな色 ・・・4個
・電圧ブザー ・・・1個



・ 4LED touch light block ...1
・ATMEGA168P-20PU ··· 1 (or, ATMEGA328P-PU)
・ IC socket (26P) ...1

・Universal Board ...1
・Tact switch ... 4
・3mmLED favorite color ... 4

・voltage buzzer ... 1

・3M Puraneji (10mm) + nut ... 2 (I forgot to take photos.)

※ ATMEGA168P-20PU and LED we used the surplus that was in the house.

Step 2: 4LEDタッチライトブロックを分解



Remove the battery cover.

To the left and right of the case, there is a nail caught.

Precision screwdriver (-) and using the disconnect.

Step 3: ボタンの位置を決めます



I will cut the universal substrate as shown in the photograph.

Drill a hole with an electric drill and reamer.

Step 4: ボタン固定のためのプラネジ用の穴を開けます



It opened two holes for Puraneji for tact switch fixed.

(See here for circuit and source code.)

In order to move on two AAA batteries, fuse bit of ATMEGA168P-20PU will be operated in 8Mhz.
The ATMEGA168P-20PU Place by writing a sketch of the "Simon says".

IC sockets and wire wearing a ATMEGA168P-20PU I and secure it with the glue gun.
