重瓣沙漠玫瑰育苗種植 (May 25, 2021)

May 25, 2021

由拍賣網站購得 重瓣沙漠玫瑰種子 進行育苗.

先將種子浸水四小時, 再放入育苗用海綿.

June 25, 2021

育苗一個月後, 有長大長高. 

夏季溫度較高, 定時噴水 及加上 營養液 促進生長.

Arduino Nano SBC 開始

因著 "智慧型 環境監控系統" 及 "魚菜共生 微型氣候監控系統"專題製作, 開始研究使用Arduino CPU板 及 相關IO模組, 感測器模組, 通訊模組, 運動模組.
需要體積小, 耗電小, 先從Arduino nano CPU板著手.

Arduino Nano SBC began with the "smart environment monitoring system" and relative of "fish and vegetable symbiotic microclimate monitoring system-Aquaponics System", began to study Arduino CPU boards and related IO modules, sensor modules, communication modules, motion control modules.

Need small size, low power consumption, start with the Arduino nano CPU board.

// nano SBC: D12 = Rx   <--------> Tx2 (Mega-2560)
//                     D13 = Tx  <---------> Rx2 (Mega-2560)

  Arduino nano SBC Software serial test

 The circuit:
 * Rx is digital pin D12 (connect to Tx of other device)
 * Tx is digital pin D13 (connect to Rx of other device)

 Note: nano SBC : D2, D3, D4, D5, D6, D7, D8, 
 D9, D10, D11 ,D12 ,D13 may using as a Software serial port.
D2~D13腳位 皆可使用為軟體串列埠
