An Overclocked Arduino DUE is quite able to emulate NES games, the emulator is based on Nofrendo Remix, contains memory hacks, because Arduino DUE has a hardware limit of 96 KB RAM. Nothing is guaranteed. NES ROM size limit is ~ 49168 bytes (It is able to run Super Mario Bros.) Used Libraries: marekburiak-ILI9341_due, greiman-SdFat, SchedulerARMAVR…
Hii.. from few days i was paying with hc-05 Bluetooth module. It is very easy to control. Since every smartphones have Bluetooth connectivity. So we can easily communicate to this module by smartphone.
Add this active suspension system to your build with the universal suspension kit from www.superscale2k20.com
This is for people that want to see more of the project in action. A short description of the build and some photos here: www.superscale2020.blogspot.com
This 3D printable ” Baby MIT Cheetah” robot is easy to build, using simple components like Arduino and SG90 servos. The robot is able to run, walk, crawl, rotate and and run in different heights, take push ups and small jumps!
Required elements:
1 x ultrasonic sensor
1 x Servo Motor
1 x buzzer
2 x led (green, red)
2 x 220 Ohm resistor
1 x 840 pin breadboard
Some jumper cables
Drawing messages on the sand is perhaps as old as history itself, but Ivan Miranda has come up with a tracked vehicle to automate this ephemeral art form. In fact, what’s seen in the video below is his second take on a sand drawing robot, boasting a much faster print speed than his 2018 version with the caveat that it prints with less contrast.
The new device features 50 SG90 micro servos spread out across a piece of square tubing, controlled by a total of three Arduino Mega boards. These intermittently extend as they’re pulled forward by a tread system on each side to produce words. The build is so long that he has to actually extend his workbench to get it to fit, and at a weight of 13.5 kilograms (around 30 pounds) without the battery, he created a custom trailer assembly to walk it to the beach.
If you’d like to build a walking biped robot, this 3D-printed design by Technovation looks like a fantastic place to start. Each leg features three servos that actuate it at the hip, knee, and ankle for a total of six degrees of freedom.
Control is handled by an Arduino Uno board that rides on top of the legs, along with a perfboard to connect to the servos directly.
Connect Four (sometimes marketed as “Connect 4”) was first published by Milton Bradley in 1974. It’s a two-player game where the players take turns dropping discs into a grid. The goal of the game is to get four of your discs in a line vertically, horizontally, or diagonally. It’s a fun game that can be quite challenging despite the deceptively simple rules. Unfortunately, the fun doesn’t last long before you inevitably lose some of the discs. Kelly Bodeman and Jack Whelan used an Arduino to create an electronic Connect Four game that ditches those discs entirely, and they have posted an Instructables tutorial explaining how you can build your own.
New ATmega644 and ATmega1284-based boards boast the power — though not pins — of a Mega in a footprint only slightly larger than the Nano.
Catalonian maker Thierry Guennou’s Pandauino has launched what he claims is the smallest ever breadboard-compatible development boards to feature the Microchip ATmega644 or ATmega1284 microcontrollers.
“644 Narrow and 1284 Narrow are the simplest and perfect upgrade option for all your small footprint Arduino projects,” Guennou claims of his designs, which use microcontrollers more commonly associated with large boards like the Arduino Mega. “The Narrow board gives you two to eight times more flash and RAM resources as compared to a Uno/Nano, plus total compatibility.”
This is a quick peek at the hardware portion of the DIY garden automation system I’ve been slowly building over the past year or so. Currently, the system is managing climate control, doing pH and nutrient dosing, fertigation schedule, light cycle, and has flood detection capability. It’s a work in progress and I’ll be sharing more about it as I go.
