Arduino ServoTimer2 and VirtualWire 433MHz Receiver

“Use low cost radio control components + Arduino to control the movements of a Servo”

Arduino video game music chiptunes

“Do you like retro games music? do you like Arduino? Yo can play Chiptune files in .MOD, .S3M, .XT, and .IT audio format with Arduino and NO additional shields or modules!”

Arduino water level indicator: the best method to measure!

“Knowing the amount of water in an overhead tank can be one tedious task. Usually youll end up climbing up the stairs to the tank and checking the level manually or until you hear the water overflowing from the top …

Bi-Directional Voltage Level Translator

“While most of my microcontroller designs run on 3.3 volts there is still the ocasional 5 volt design. Or I do something with an Arduino. So the need may arise to interface between logic working at different voltage levels …

Bluetooth Controlled Motorized Camera Slider

“We really love photography and camera gear here at Adafruit, so we came together and upgrade our original 3D Printed DIY camera slider. It’s now motorized using a single NEMA-17 stepper driven by the Adafruit Motor Shield ontop …

Cheap homemade 30 MHz - 6 GHz vector network analyzer

“Vector network analyzer (VNA) are used to measure scattering parameters of high frequency circuits. When frequency is high enough the reflections of the waves start to matter and distributed effects need to be taken into account. VNA can be used …

Dual 90V/10A Unregulated Power Supply

“This project is designed to provide symmetrical output unregulated, high voltage, high current for your demanding needs. Right choice for Audio Amplifiers, Power Drivers, Motor Drivers.”

E-Kart: The electric Go Kart

“For our final technical project we decided to build an electric go kart using commonly available components. The requirements were to implement project management principles, hardware, and software design. The project build time was about 3 months, but the research …

ESP12e oled “smartwatch”, honestly it’s a wrist display ;)

“Recently I bought two ESP12e, wanted to see how those IoT things work. One thing I know for sure, they don’t tolerate 12V 1A ;) yep fired one by accident … I left with one working, trying to figure out what …

Every Liter Counts! Arduino Water Doser “Shield”

“Hi! With this instructable , you can dose a desired amount of water. The system can work in mL and L. We will use an Arduino UNO, a flow meter to count the amount of water, a LCD to show the …
