 大家好, 歡迎收看本週的Weekend project with Stonez56。 

本周要進行的是 App Inventor 第10集 -  自己來寫 YouBike 2.0 APP (下集), 這個影片適合初學者來觀看學習, 想拿來這個單元來學習 App Inventor 2 也是很 Ok 的!  

上集影片請點此: https://youtu.be/D78-eDRFiXM 




對了,如果你沒有看過上一集, 請記得到右上角這邊, 按一下先觀看上集再來看下集.  那相信看過上一集的朋友都在等待這一集呢!   這個是一個專門為初學者來開發的一個系列, 所以會講的比較詳細, 相信各位只要仔細收看內容並進行實作, 一定會收獲滿滿滿。好, 那我們就開始吧今天的練習吧~


本集目標:

* 資料由政府資料開放平臺即時更新

* 美化使用者介面 (加入 Splash)

* 加入 App 開機畫面

* 移動 maker 更加順暢

* 打開 App 自動讀入 Json

* 取得手機所在位置定位

* 顯示附近 YouBike 車輛數目 (比對 YouBike 2.0 App 數量)


使用位置感測器, 注意權限:

* 位置權限要授權給 MIT App Companion 

* 若是下載為 APK, 位置權限要授權給 APK

* GPS 精準要打開


如果時間不夠的朋友, 也可以從以下的時間軸挑選想看的部份即可!

Arduino - DFPlayer Mini MP3 Module

Image
Arduino - Test DFPlayer Mini MP3 Module I found DFPlayer mini MP3 module on China auction site Taobao when I was looking for a MP3 player module for an Arduino projects.  This module is quite small and it only require few pins connections to Arduino and a speaker to work.  Looks really nice for my little project. Actually, the module is quite capable and complicated, if you were interested, please visit this  page . This tutorial here is just to show you how to connect DFPlayer module with Arduino and speaker and the Arduino sketch provided here just to play few sample sounds I collected from Internet. First, I recycled a 2W, 4Omh small speaker from this little music box. Material Needed: DFPlayer Mini module  Speaker - DFPlayer module support to to 3W SD card - 2GB ~ 32GB formatted with FAT or FAT32 MP3 / WAV - audio files Arduino mini Pro Few jump wires As you can see the illustration below I made in Power Point, hardware connection is quite simple (

Android control color RGB LED using HC-05 Bluetooth with Arduino (Part I) Part II of this tutorial is here! Updated Sketch for ESP32 boards   https://stonez56.blogspot.com/2021/07/android-control-color-rgb-led-with.html This time, I am going to show you how to use Android phone to connect to HC-05 Bluetooth module and Arduino. Hardware needed: Arduino mini pro * 1 HC-05 Bluetooth module * 1 RGB LED * 2 Jump wires * 10 HC-05 Bluetooth Module wiring as follow: TX connect to Arduino Pin 11(RX) RX connect to Arduino Pin 12(TX) Remember to connect TX on the HC-05 to RX on the Arduino and RX on the HC-05 to TX on the Arduino, so Arduino can receive data correctly. VCC connect to 5V power GND connect to Ground RGB LED wiring as follow: Warning: You must connect Arduino mini pro, so your PWM Pin can control LED’s color! For example, Arduino mini pro only has 6 PWM pins and they are 3, 5, 6, 9, 10, and 11, other pins do not have PWM. Refer to Wikipedia for PWM R co

Arduino #27 AsyncWifimanager ElegantOTA ESP32 (WiFi Password Mgnt. + WiFi Firmware Update)

Image
*** If you are using the ESP8266, Please see this:  ESP8266 It would be great if every IoT device deployed with OTA capability with Wifimanager.  Then the IoT device would be able to change SSID & password without connecting the device to the computer to update SSID and password as well as FOTA at any time when you wanted. In this tutorial, let’s combine ESPAsync_Wifimanager and AsyncElegantOTA into a code base to become a handy tool for future IoT projects!  I have made WiFiManager & AsyncElegantOTA tutorial videos. If you don't know what they are and how they work for IoT projects, I strongly recommend you to watch these videos first. This time, I used ESPAsync_WiFiManager library, it's because WiFiManager does not work with AsyncElegnatOTA together. We have to change to ESPAsync_WiFiManager.  The main reason for this is that AsnycWiFiManager is using Asynchronous technology. Which means it can accept connections from different sources at the same time. So, while WiFi
