Wireless Lock Tone
Upon acquiring the car, it was appreciated that it did not emit a "chirp" or sound the horn each time the doors were locked or unlocked. There are occasions when discreetness is preferred regarding entering or exiting the vehicle. However,...
valved transmitter for 3.5 MHz
This transmitter project is a highly efficient, rugged, and simple low-power continuous wave (C.W.) unit delivering more than 10W. It is crystal-controlled with stabilized high tension (H.T.) and features a buffer stage between the crystal oscillator and power amplifier stages,...
controlling your trains with an arduino
Arduino is an open-source electronics prototyping platform that features flexible and user-friendly hardware and software. It is designed for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from...
audio Using a microphone with an Arduino
This project requires expensive hardware, including a microphone and amplifier, along with sophisticated audio analysis on the microcontroller. Even a complete microphone with an amplifier circuit does not yield the desired results, as noted in the product comments. The individual...
Small Radio Transmitters
Information about building a small radio transmitter, which has a PCB measuring 1.75" x 2.5" (45mm x 68mm) and has a range of approximately 30 yards. The documentation states that the frequency range is 100-108 MHz, but it has been...
DSpace badge board build Instructions
This project is designed to assist in a basic course where students create a simple AVR/Arduino-based badge. It serves as a beginner's soldering project, resulting in a small object with blinking lights that can be worn around the neck using...
Simple Short-Wave Transmitter
This low-cost short-wave transmitter is tunable from 10 to 15 MHz using a ½J gang condenser VC1, which sets the carrier frequency in conjunction with inductor L1. Frequency trimming is achieved with VC2. The carrier signal is amplified by transistor...
Arduino GSM Shield
The Arduino GSM Shield connects an Arduino board to the internet using the GPRS wireless network. To use this module, it must be plugged onto the Arduino board, and a SIM card from a GPRS coverage provider should be inserted....
sensor Arduino analog signal read problem
The piezo element is connected solely to Channel 1 (Arduino A[0] port). Channels 1 through 6 are linked to female mono jacks, with the ground (GND) wiring arranged in series from jacks 1, 2, and 3, continuing to the end...
