This is the actual circuit of my Arduino LED Controller - the first self-built project of mine!
The 5 switches control 1 LED each, cycling each one through 3 states - Off, On, and Flashing. The LEDs are completely independent of each other.

We'd love to hear from you if you use our photos/documents.
Many other photos in our collection are available to view and browse on website.
Assassin's Creed Origins is a game published by Ubisoft. This image is taken with the in-game photo mode. I use an X-box controller connected to my PC and access the photo mode by pressing F3.
This is a microcontroller-powered temperature controller for a fridge I built out of fabricated necessity and spare parts last weekend.
Backstory: We replaced our ancient 2nd fridge with a big new upright freezer, which left our little chest freezer empty. Sometimes we do need the extra fridge space though during harvest season at the farm, so I figured I could just turn the temperature up on that old chest freezer and turn it into a fridge. Nope. Highest it goes is -4C. OK. Time for some gratuitous technology. See the notes.
7S battery pack with equally ballanced 18650 cells of 2200mAh (or 15.4Ah x 3.7V = 57Wh) with no BMS. Purpose built BLDC motor controller (ESC) with built-in wireless receiver. Sensored hub motor.
I like the little battery cozy it comes with. I was also impressed that there were batteries in the box for all the controllers.
Laatste nieuwe aanwinst, de ROBOTICS TXT Controller. Samen met de ROBOPRO software is dit een grafische interface om je programma's te maken voor de controller. Ik ga deze controller boven de FPGA controller gebruiken waardoor ik meer mogelijkheden heb om de kogelbaan te sturen en vooral verschillende programma's te gebruiken zonder opnieuw de FPGA te moeten programmeren. De communicatie tussen de Robotics TXT en mijn FPGA zal gebeuren met de externe I2C connector. Zo kan ik alle data van de FPGA snel inlezen en ook commands terug sturen.
De software op de PC is hier al aangesloten en in gebruik. Een eerste testprogramma om de externe I2C driver te gebruiken draait al en op de scope zie ik de data op de I2C bus al verschijnen zoals ik die in de grafische editor op de PC heb aangemaakt. Nu nog de I2C slave driver voor de FPGA schrijven maar ik heb een aantal voorbeelden gevonden en ga daar de beste wel mee verwerken.
Natuurlijk heb ik ook al een kleine test gedaan om een aangesloten motor te sturen en zelfs ook om en rotary encoder aan te sluiten en uit te lezen. Je kunt ook de online mode gebruiken en dan komen de resultaten op je PC scherm.
Oef, weer een heel ander stuk software te verwerken maar gezien de high level gaat het enorm snel!
PC wordt aangesloten via USB of netwerk volgens keus. Er zijn heel veel programma's beschikbaar, voor je I2C chips bestaan de meeste toepassingen reeds kant en klaar.
My girlfriend got into the excitement surrounding the launch of the Wii, and made these cookies based on the classic Nintendo controllers.
Xbox Controller. Took with Enickcnln's camera :D (Which is totally fricken awesome.)

This is finally getting real! I hired a technician to assemble two copies of my controller board design for me. So this is officially the first prototype. Next step: set up software development environment and download some code into this puppy!
From quarterarcade.com/.
I kinda should not have bought this. It was the most expensive control panel + controller they had for sale and by a wide margin, but I WANTED one and this controller is hard to imitate. At least until ram-controls.com/ gets ready to ship their (religiously accurate) remake of this controller.

This closeup of the solder side shows the pull up resistors for the TC74 I2C lines, made from four 2.2 KOhm SMD resistors.
I 'finished' my PAP (Pole Aerial Photography) controller and camera rig today :-)
This image shows the controller. It has a knob to adjust the tilt of the camera frame and a button to trigger the camera.
The tilt and trigger signals are sent to the camera rig by radio (inside the box).
The box also contains a small receiver (antenna is visible on images) that receives a live video feed from a small camera on the rig (to allow precise aiming). This feed is displayed on a small TFT display.
The box is powered by a LiPo battery that should last a few hours...
The sensors and radio are controlled by a small computer: an Arduino Nano

The TXT Controller controls the magic bullet track here. All inputs and outputs have been used. The I2C was not used here. Because so many GND connections were needed, I made an expander block that can hold up to 15 connections. The TXT can work in both online and offline mode.
De TXT Controller stuurt hier de magische kogelbaan. Alle ingangen en uitgangen zijn gebruikt. De I2C is hier niet gebruikt. Omdat er zoveel GND verbindingen nodig waren heb ik een expander lat gemaakt waarop tot 15 aansluitingen kunnen zitten. De TXT kan zowel in online als off line mode werken.
