最近、Arduino Yun を入手してから Temboo を使用していますが、Choreos を組み合わせてデータを取得および投稿する際に問題が発生しています。
私は Yahoo GetWeatherByAddress Choreo を使用しており、必要な個々の値を Xively フィードに投稿しようとしています。Xively Write Choreo を使用し、FeedData を JSON 形式で入力しています。
これまでのところ、一度に 2 つの値 (湿度と圧力) を投稿することにある程度成功しています。残念ながら、私はこれ以上のものを使用したいと考えており、湿度、温度、気象条件 (晴天、強風など) と、ブレッドボードからの LDR の読み取りが必要です。したがって、10 秒ごとにループし、それらの値をすべて読み取り、Xively に投稿します。コメントを外した温度値以上のものがある場合、温度値はシリアル モニタへの出力にも問題があるようです。また、プロセス全体を実行するわけではありません (成功の場合は Http 200 を返します)。値を送信し、次の値のセットが取得されるのを「待機」するだけです。ここでどこが間違っていますか？
