  • How  to Use Scratch or Arduino to Program a MBot With Makeblock

    In the photo in Step 7 showing the Scratch (mBlock) code for navigating the car using the Up/Down/Left/Right Arrow keys, seems to have a bug which should prevent the right arrow key from working. Look at the fourth If/Else block. It says that when a "down arrow" occurs (which already was processed by the second If/Else block of code) to drive the two motors the opposite direction as was done for the "left arrow". Assuming the "left arrow" code is working, then the car should turn right if you reverse the voltages as compared to the left arrow code. So I suspect the bug is the that this fourth If/Else block should looking for the IR Remote condition where the right arrow is being pressed, not the down arrow!

    Physical Computing - Scratch for Arduino

    Have you had the chance to interface a IR remote control and IR receiver component to S4A? I am an educator trying to excite kids into Physical Computing and was thinking that the next step after Makey Makey and a few intro classes into S4A would be a project that uses an IR Remote control and and IR receiver as was dome in this Arduino C project:https://arduino-info.wikispaces.com/IR-RemoteContr...It uses a Arduino Library and I doubt that such C coded libraries are compatible with S4A, but it might be possible to translate the code. Was wondering if you might have already done so, or know someone who has. An IR controller with an application that would allow students to write various scripts to control things remotely would seem like the next great thing beyond Makey-Makey which is a ...

    Getting Started with ArduBlock

    For those of you who are interested in ArduBlock, be sure to check out BlocklyDuino, Blockly@duino, BlocklyDuino-Enhanced and TUNIOT. The later two were developed by the folks at EasyCoding.TN. Can use Google, or other search engines, to search for other versions of BlocklyDuino. TUNIOT is especially cool as it supports the ESP8266 based NodeMCU boards to provide you an easy way of developing WiFi (IoT or Internet of Things) applications. Search for "Espressif ESP8266 WiFi SoC", "Arduino ESP8266 Core", "NodeMCU". Forget the firmware based eLua language that comes with the NodeMCU. Focus on getting the NodeMCU up and running with the Arduino IDE (requires installing the Arduino ESP8266 Core from GitHub). Then can go to the EasyCoding.tn website and click on ...

Then can go to the EasyCoding.tn website and click on the TUNIOT icon to launch TUNIOT (runs off their server). The EasyCoding website also has links to a series of YouTube tutorial videos they did that describes in detail all this and more. Thats www.easycoding.tn

  • Get Started with ESP8266 Using AT Commands, NodeMCU, or Arduino (ESP-12E)

    I recommend using the Arduino IDE with the Arduino ESP8266 Core installed. If you are new to C programming, then check out TUNIOT, a version of BlocklyDuino Enhanced with WiFi code blocks developed for the NodeMC board. You can plug code blocks together like in Scratch or Blockly and the resulting code is Arduino C. They have a series of tutorial videos on using TUNIOT with the Arduino IDE and NodeMCU board on YouTube. I'll give the links below. There Tutorial #10 will show you how to get a HTTP WiFi Server up and going. The web page is a "one liner", but if you know how to code HTML, you can create a pretty nice web page. You can create a webpage with a banner, a couple pages of text, a bunch of hyper-links and a number of photos, I use the old HTML <table> tags to form...

You can create a webpage with a banner, a couple pages of text, a bunch of hyper-links and a number of photos, I use the old HTML <table> tags to format the layout, but if you know CSS, you can use <div> tags and in-line CSS to do your layout. Have yet to play extensively with CSS, but the basics seem to work fine. The images I display are hosted on another webserver on the Internet as the NodeMCU has limited Flash memory for storage. Just use the complete URL and it should pull up the image w/o problem. Maybe I should do an instructable.
