Peggy – Arduino Portable RF Rain Tracker

My country mild climate lets the sun to shine for the greatest part of the year, then tumble driers are not widely used and so we often use to drain clothes in the sun. What to do when a sudden rainfall comes? This project has been made for anyone drain clothes in the sun or, simply, needs an alert when it starts to rain. "Peggy" project is a simple portable rain traker that uses a rain sensor, 433 Mhz tran ...

Arduino Assisted RC Truck/Car

Recently I dusted off my 7 year old Stampede 2wd, designed in 1996. I got it for my 8th birthday. The truck was great, but it had a few caveats. For example, if the truck ran out of range, battery was low, or the transmitter batteries died on you, the truck would keep the throttle on the last position. Thanks to this accidental cruise (out of) control (See what I did there? 0_o), I accidentally drove m ...

A Levitating Sphere Rotates Glows and Blinks With Arduino

A levitating little Death Star in Instructables invited me to the new project with Arduino. Three policies were decided and kept to differentiate it from the forerunner. Do it myself with no (or less) ready-made.Keep rotating.Make glow and blink without battery.VIDEO(1): A Levitating Sphere Rotates Glows and Blinks https://youtu.be/nOx0rIQFgoY The detail of the project is described below. Let’s wrap co ...

WattUp – RF based Wireless Charging at a Distance

Recently, many big companies such as Samsung have developed wireless chargers which work by induction. These chargers usually consist of a station which needs to be in contact with the device in order to charge. The station defeats the purpose of being able to move and walk while still charging the device. Energeous, a global leader in RF- based wireless charging, created the award-winning device WattUp in ...

Teardown and experiments with a Doppler microwave transceiver

I got a couple of Microsemi’s C900502 10.525 GHz X-band Doppler radar motion sensors a while ago. This batch was made in UK and had “UK patents 2243495 and/or 2253108 apply” printed on the case. I have seen a teardown of an HB100 Doppler radar module before and was wondering if I this one is any different inside. The C900502 transceiver has a very sturdy metal casing. It is measured at roughly 5cm by 5cm by ...

Arduino 433Mhz RF Wireless Data Transfer

The most practical and cool way of sharing data from 1 Arduino to another is by far using a radio transmitter and receiver. The simplest form of wireless transmission (I could find) is the 433Mhz ASK modules. They come in pairs, a receiver and a transmitter. They are ridiculously cheap, selling at $1 or less a pair!! These modules provide simplex 1 way data transmission, in order to get a 2 way communicatio ...

DIY Six Channel Arduino RC Transmitter

It’s wasn’t so long ago that RC transmitters, at least ones worth owning, were expensive pieces of gear. Even more recently than that, the idea of an RC transmitter running an open source firmware would have been considered a pipe dream. Yet today buying cheap imported transmitters and flashing a community developed firmware (if it didn’t come with it pre-installed to begin with) is common place. It’s not m ...

Wireless temperature and humidity monitor for baby’s room

This project describes a DIY wireless temperature and humidity monitor for kids’ or infant’s room using the Arduino platform, and inexpensive and easily available ASK transmitter/receiver modules. On the transmitting end, an Arduino nano senses the ambient room temperature and humidity using the DHT22 sensor and transmits the data to a receiving end Arduino over a 433 MHz ASK RF link. The receiving side Ard ...

Drone The Quadcopter

"Drone The Quadcopter" is an featured UAV. I design my project with F450 arm in X-mode design. The full operation takes place via a Flysky FSCT6 remote control unit which gives a better operating range of 800 Meter to 1.2KM. If you are a beginner in this field then you are on the right place. The ultimate goal of our project is to learn aerial vehicles which can be flyover a long height and over a long rang ...

Doorbell

Connect your door to the Cloud and open it from everywhere. Story The Doorbell is a great example of how to connect your devices to Arduino Cloud and make them talk to each other. The Doorbell allows you to open the door from everywhere as long as a WiFi network is available. The project is composed of two part: the transmitter and the receiver. The transmitter is the one that actually opens the door and it ...
