#40 デジタルポテンショメータ(8bit)

Tibbitの配置

Tibbit #40を挿入します。
#40-1から4は抵抗が違いますが、どれもノードの使い方は同じです。

ノードの配置

抵抗を指定するために、functionノードを使用します。

以下のようにフローを配置します。

functionノードの編集を開き、コードに以下を記述します。
0から256までの数値を入力します。（抵抗値はTibbitブロックにより異なります）
#40-1は256で5kΩになります。

msg.payload = 256;
return msg;

1 2	msg.payload = 256; return msg;

ノードの設定を開き、スロットを選択します。
Node-REDデプロイ後、injectノードをクリックすると抵抗値を指定することができます。
