About Sherry

I'm Sherry from ITEAD studio. Now I'm in charge of the daily editing of ITEAD blog. As a start learner, maybe I'm not qualified to answer most technical questions you've left in the comment, but with our engineers' help, I'll try my best to help you find the way out.

Arduino Based Time Attendance System

A time attendance system machine may be the first thing you meet when you go to your office and start your work. The most common type is using card. In this blog, we will use Arduino and several modules to create a simple time attendance system.

2015 International Labor Day Schedule

Because of International Labor Day, ITEAD STUDIO will have a three-day holiday from 1st to 3rd of May. Here, we would like to release the schedule in advance: 

Ordinary orders received from 27th to 28th, April will be processed normally as usual, while for orders on 29th and 30th, we will try our best to deliver before holiday – but as it takes time to deal with packaging, we cannot guarantee that orders in these two days can be sent out before the holiday. Thank you for understanding. For the pending orders received before holiday and during the holiday, we will process on 4th, May – due to backlog of orders during the holiday and increase of orders in post office after the holiday, we estimate that orders may be processed slightly slower than usual. However, we will make our efforts to deliver as soon as possible.

For orders of PCB service, generally PCB production costs about a week, while the number of orders often increases before the holiday, thus it will need a longer time to be processed. Therefore, we cannot guarantee the orders of PCB service received from 27th, April to be shipped before the holiday. However, for files received from 27th to 30th, April, we will arrange production, but the finished boards will be received and delivered after the holiday. For orders received during the holiday, we can only arrange the production after the holiday.

Above is our holiday schedule. For any inconvenience caused, we do hope you can understand, and you can arrange time for placing orders according to your own needs.

Weather Station: Use Nextion 4.3″ with Wboard

Note: Please read the updated tutorial here: Nextion Weather Station Tutorial 

We use Nextion 4.3" and Wboard Pro to make a weather station. Using this station, you can check any city by typing city's name in the input bar. The weather information is provided by Weather Underground server.

PS: WBoard Pro is a Wifi development board based on Arduino MEGA. With an on-board ESP8266 chip (WiFi firmware has been burnt in), you can drive ESP8266 to connect WiFi and visit the internet by controlling the serial ports.

Wboard Pro ESP8266 Firmware Upgrade

Wboard Pro has an on-board ESP8266. If you want to upgrade the ESP8266’s firmware, here is the instruction.

Preparation

  1. The jumpers’ connection. According to the silkscreen on Wboard Pro, you can learn the jumpers setting. Choosing to connect different jumpers, you can let the serial port connect to Mega 2560 or ESP8266. As we upgrade the firmware to ESP8266, we shall plug the jumpers to 4-6 and 3-5. BTW, the FW jumper shall be plugged as well.
  2. Firmware. In this tutorial, the firmware we flash is 0.18 version. If you need a higher version, please go to the forum of ESP8266 to get one. Note: in this case, the default firmware that Nodemcu flash to your ESP8266 is not AT commands firmware!!If you want to flash AT commands firmware, go to ESP8266 forum.
  3. Firmware flasher. The flasher we use is Nodemcu. You can click here to get this flasher from Github, and learn how to use.

Product Preview: Nextion in an Arduino project (3)

In the previous blog, we demonstrate how to use Arduino to control a progress bar that shows on Nextion 2.4”. In that case, we use progress bar and text components in Nextion Editor. In this blog, we will tell you the other simple component – button. When you touch the area that is under the button component “monitor”, it will run the ID of this component, then you can realize some visual final effects like interface switching, sending data through serial port.

Hardware we use

  • Iteaduino UNO
  • Nextion 2.4"
