“Cardbot is a functional robot made from laser-cut corrugated cardboard. It is battery powered and wirelessly controlled over 802.15.4 (Zigbee.)….I had the idea that I could build a kit for a robotic base, itself a press-fit assembly kit, that could also serve as a mobile base for other press-fit constructions.”

“This device acts as interface between your microcontroller project and a GSM phone. It handles all modem data communication between the GSM phone and your micro-project. The best thing is that it decodes PDU into TEXT on the fly!”

“A few days ago I presented the ADK in Google’s blog. It’s a platform that enables communication between Android and Arduino terminals. The downside was that the development kit costs about 300 €. After seeing someone online who managed to run the ADK on Arduino with a USB Host Shield controlling a servo or LED, we wanted to do the same but a BricoGeek DIY version.”

“This hack is about rewriting the firmware of PLL FM transmitters based on AVR microcontrollers to add more functionalities. They’re commonly available on eBay from various sellers and for prices ranging from $40 to $80, depending mostly on the RF output power.”

“In this article, we will show you how to build a system where the input and output have seperate microcontrollers and are linked together using XBee modules. The input system will use an infrared distance sensor to measure how far away an object is from the sensor and the output will drive a standard DC motor using a power transistor.”

“We purchased an RC car, removed everything except the body and the motors, and replaced all of the circuitry with our own microcontroller-controlled network. We also built our own controller using just the existing case. For the transmission of control signals, we used a 418 MHz transmitter/receiver pair purchased from Abacom Technologies.”

“The servo switcher is designed as an aid for anyone who wishes to convert a remote control vehicle into an autonomous vehicle, in this case the project is a sailing boat, however the design can be easily expanded to work with cars, planes or helicopters.”

“ In this article, we will use a PIC 18LF4520 and an Arduino UNO to build a transmitter and receiver using some wireless modules. The PIC will output serial commands as a transmitter that tell the Arduino system to pause an LCD screen from updating a counter value. This project is intentionally designed to be simple because there are many simple ideas at play and it’s important for you to understand each one.”

“In this article, we will go step-by-step through the process of understanding, designing and building a system that uses an infrared proximity sensor for input, correlates that input to how far away an object is from the sensor and then drives a motor and some LEDs at distinct speeds depending upon the proximity of the object.”
