Arduino Motion Sensor
Give your Arduino board a motion sense around it! Use any Arduino board: Uno, Mega, Duemilanove etc.
To implement motion sensing capabilities with an Arduino board, a typical circuit would involve the integration of a passive infrared (PIR) sensor, which is...
AJAX read switches analog
Flicker-free updating of analog input and the status of switches using Ajax and the Arduino Ethernet Shield. The Arduino Uno is configured as a web server.
The described system utilizes an Arduino Uno microcontroller, which operates as a web server to...
Arduino based camera trigger circuit
The core of the circuit features an Arduino microprocessor, represented by the header pins on the left side of the circuit schematic. Two analog inputs, labeled 0 and 1, are connected to the emitter sides of TEMT6000 ambient light sensors...
arduino based remote control for electric door
A replacement remote control system for an electric garage door was constructed after the original remote failed multiple times. Although the old remote could have been repaired, it was 35 years old and not particularly enjoyable to use.
The replacement...
Perfboard Hackduino Arduino-compatible circuit
ATMega168 or ATMega328 microcontroller chip with Arduino bootloader (the one on your Arduino can be used temporarily) costs between $4.00 and $5.50. It is advisable to purchase an unbootloaded chip from Mouser for a lower price or a bootloaded version...
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...
Driving circuit schematic
The driving circuit depicted in Figure 18-12 consists of a connection between the driving portion, the microcontroller, and the air conditioning operation components of the bridge. The microcontroller's digital signal levels from ports P4.0 to P4.3 (approximately 12 feet) and...
Experimental I/O board for microcontrollers
For beginners experiencing similar challenges, a general-purpose I/O board is recommended to minimize prototyping time and maximize space on the breadboard for projects. The construction of this board is straightforward. Basic I/O devices can be soldered onto a general-purpose perforated...
Smart Sensor Glove
To compile this software, simply copy and paste it into any current or newer version of the Arduino software. To compile and check for errors, click the play-like button and wait for the software to process. If any errors are...
