Hello all! I've been building sci-fi models for about 7 years now. Just last year I got into lighting them and I never want to stop. The effect is so cool. However, I've had this one kit sitting in my backlog since I started. It's the Revell 1:500 Star Trek Into Darkness Enterprise. I haven't started it until I knew I could do it "justice" in my eyes. So in comes Arduino.   I've been dinking around with code and have had troubles really grasping what I'm writing. I can assign pins just fine, but after that... I saw a thread on here about a similar topic and figured this would be the best ..read more

Bar Graph with Neopixel

Hi there everyone, hi @Hans. After the very successfull Power Rangers Project, I got a new one. Who does remember the "old" bar graph displays for showing battery status or as a level indicator? This was used for the Ghostbusters Neutrona Wand. And while there are a bunch of LED bars with controllers and programs for that, they are just multiplexed LEDs. And therefore just one or two colors. What if we use WS2812 instead? So we can have great color effects and a bunch of animation effects and without the need of extra microcontrollers and a bunch of cables. Of course it later must be a cus ..read more

Help with MFRC522 RFID Reader: Reading Data and Detecting Card Removal

Hello everyone, I'm working on a project using the MFRC522 RFID reader with Arduino, and I've encountered a couple of challenges that I'm hoping to get some advice on. My project involves detecting an RFID card, reading a nickname stored in a specific block on the card, and accurately detecting when the card is removed from the reader. I'm using the MFRC522 library for this purpose. 1. Reading a Nickname from a Block: I've successfully managed to read the UID of the card and can authenticate with a specific block to attempt reading data. However, I'm specifically interested in reading a ..read more

Arduino Switch Case no break

Hi everybody! I dearly need some help with this sketch! I have a toggle switch on a MEGA 2560. Each time the switch is pushed, a counter goes up by 1. Reachind "8", it is reset to "0". This part just works fine. BUT: When I add the Switch Case, it gets stuck in "case 1". The serial printer gives out "mainSwitchcounter1?" and "1". On and on. And the LED does "on/off" forever. So the "break" does not work. What am I missing? Your help would be highly appreciated!!! // for MEGA 2560 // Each time the mainSwitch is activated, the counter goes up by 1 and calls up a corresponding Switch Case sectio ..read more

FastLED Light effects for Power Rangers

Hi folks, as you might know, Im not a coder. And because I only use Arduino for some of my scale model projects, I just get lost everytime I start coding again. So, thats why I don´t know where to start and Im stuck on "easy" tasks. Im not just a Trekkie but also a big classic Power Rangers Fan. So I bought a Hasbro Lightning Collection Power Morpher to change the toy like electronics and make it my own. The toy has a coin recognition (the coins have nodges which press buttons). So depending on which buttons are pressed, the light has different colors. I would like to keep this idea, so I can ..read more

Arduino 2.0.4 Code - I am trying to learn to use CAN with Arduino. I downloaded this code to help with my learning curve. But it gives me this Compilation error: "cannot declare variable 'CAN' to be of abstract type 'MCP_CAN'" and highlights the 8th & 14th lines.

I have never worked with code or anything like it until about a month and a half ago. I am writing this code to be triggered by inputs to turn specific light sequences on. Any help in what I have wrong would be greatly appreciated! I am going to copy what I have here and hopefully someone can point out what I have wrong and help me fix it. #include "FastLED.h" #include <Adafruit_NeoPixel.h> #define NUM_LEDS 100 #define DATA_PIN0 11 #define DATA_PIN1 10 #define DATA_PIN2 9 #define DATA_PIN3 13 #define CHIPSET WS2811 #define BRIGHTNESS 200 #define ON 1 #define OFF 0 CRGB leds; void set ..read more

Hi there from Arduino nerd needing help. I have posted a similar problem on Arduino forum but cannot get any help ( Probably my fault and not their's), with what seems like a very simple "Case statement". int aaa = 0; int z1 = 0; int z2 = 0; void setup() { Serial.begin(9600); Serial.println(" Begin"); } void CasE() { switch (aaa) { case 1: // /* Serial.print(" START CASE 1"); z1 = 12 * 12 / 2 + 45 - 31; Serial.print(" Z1 ="); Serial.println(z1); // */ break; case 2: Serial.print(" START CASE 2"); int z2 = 12 * 12 / 2 + 45 ..read more
