Arduino Robot 3 - Line Follower (Goals & Notes)

-
Work has begun on my third Arduino Robot. I decided that after some comments I read in various forums, that making a line following robot would probably be a proper increase in challenge. With research in hand, I placed my orders for parts and began looking into creating a test track. Here are the goals for Arduino Robot 3 - Line Following Tank:
  1. Conform to Robo Games Line Following Rules (2010) 
  2. Use only a single sensor.
  3. Robot should move in a smooth motion (no twitching about the line)
I have begun the physical build, but I'm still looking into a 'practice arena'; I may end up taping together printer paper...

Full report, code and video upon completion (so check back here).

Edit: The reason for the single sensor goal is because someone trying to do similar with a Lego robotics set would only have one sensor. I do not want to be putting more money/hardware into any of the robots. They should be a challenge; and with my programming background I think that even two sensors (let alone an array!) would make this too easy. This is because two or more would allow a basic edge following; three or more would allow the robot to distinguish line direction (veering).  The robot may be improved to have multiple sensors; but I feel I can defeat the challenge with one.

Very interested to see your solution using one sensor. That sounds tough to me. :)

Resuming My Robot Work With Bonus 3D Printer Project

Well after a long break of working on the house; this blog will be returning to a primarily robot programming focus. My work on the house is shared elsewhere... So; I've resumed work on my robot and added a second Arduino to my arsenal; this way I can prototype ideas without disassembling the robot. I have used it to go through the tutorial for the TFT screen: The new Arduino is an UNO; they come in much more sophisticated packaging than their predecessor: That is a sticker sheet on the right and a EULA in the middle. The first nice thing to notice about the UNO is it auto switches the power source. You can see this difference and other slight changes in the comparison here: So; I will post about the robot again when line following can be demonstrated and the code is ready to share. I hope to share two versions (with and without TFT info printing). With that; the other exciting news is that I am building a 3D printer; which I will document here and share my proble

Create a "GG Button" With an IOT Button on Discord

I was having some fun with my internet button (found here: https://store.particle.io/collections/shields-and-kits), and also working on some bot coding. So I decided to bring the two together; with the goal of pressing a button to summon a bot to my channel to play a sound effect(s). This would be similar to the famous https://www.ggbutton.com/ button, but would play a sound to everyone I am in a Discord channel with. Since I was already working with Darkside's SoundBoard bot for Discord; I decided to utilize the API. That way I'd be creating a simple web hook that could later be used for other purposes; like having Jenkins run a build/deploy. You can see the completed work in action: This comes from this source code: 1: // This #include statement was automatically added by the Particle IDE. 2: #include <HttpClient.h> 3: 4: // This #include statement was automatically added by the Particle IDE. 5: #include <InternetButton.h> 6: 7: /

Fixing a dead Sansa MP3 player (Versions e200 e260 e280)

First, here is the player we are discussing, or at least your average version: Although if you are here, you probably don't see the nice shiny interface above. That's a shame, but we'll try to fix it. This all started for me when a friend got a bag of crap from Woot! Among the loot, were quite a few dead Sansa e2XX players. You have to use the e200 tool to reflash them, it works better under Linux, and I run Linux (Ubuntu if you must know). So I ended up in a deal where I would try to fix all three. They were all fixed, and below I share how I eventually got all three working. There are many posts on the web about how to fix these. They involve going into factory mode and flashing the firmware. Unfortunately a measurable percentage of people find that to be completely useless because if you can't get the device into factory mode then you can't update the firmware. Let's troubleshoot a Sansa MP3 e2XX player. Keep following these steps, if you make it to t
