Arduino based LCD Digital Clock

This is an Arduino based digital Clock to display real time on a 16x2 LCD using a DS1307RTC module. The date and time can be set via serial interface or push button switches.

This is a solution on how to fix the problem where my Seeedstudio RePhone Mass Storage Mode is not working probably.

Mass Storage Mode works in first time, subsequently it does not appear as a "Removable Disk" (Red LED ON, Green LED OFF). I do get Alcatel single RNDIS network interface under the device manager, the RNDIS interface is keep on rebooting every few seconds. This problem only happen on Win7, WinXP is working fine.

You can fix the problem by disable the "automatic driver installation"

Disable automatic driver installation

There's a few ways to disable the "automatic driver installation"

Scan for hardware changes

  • Open "Device Manager" and navigate to "Network adapters"
  • Right click on "Alcatel single RNDIS Interface" and select uninstall
  • Click on Action Menu on the Device Manager and select "scan for new hardware changes"

I'm not a Smartphone addict, I never interested in the features of Smartphone or which Smartphone is best for me. However, as a DIY enthusiast, the Seeedstudio RePhone catches my eye.

The open source hardware manufacturer (SeeedStudio) published the world's first open source, modular Smartphone (RePhone) in Kickstarter on September 23, 2015. RePhone is a GSM +BLE (Bluetooth Low Energy) phone, future version will support 4G LTE. I own a RePhone DIY Kit from Gearbest.

Updated on 23 Mar 2016
Gearbest currently running a flash sale on electrical & tools, you can buy it for cheaper than the creator(Seeedstudio).

Thank you my friend Siew Goh Chuang, he made this beautiful LED cube:  This is a 8x8x8 RGB LED cube project, a modified version of the LED cube which originally designed by Kavindarrah. This project only modified the hardware but leaving the software (source code) intact. All the source code is available in Kavindarrah's website.

ESP 07 Arduino IDE
The ESP-07/ESP-12 is a generic ESP8266 module which have no bootstapping resistors on board, insufficient decoupling capacitors, no reset circuit, and no USB-serial adapter. This is an article shows you how to connect the bootstapping resistor to the ESP-07 module and upload sketches onto the ESP-07/ESP-12 using the familiar Arduino IDE.
