Arduino talking to Excel
Gobetwino is relatively easy to use. The Arduino can send words to the serial port, and Gobetwino interprets them as commands to perform various functions, such as creating CSV files and sending emails. This program has been tested by using...
AM sofware radio using Arduino
Markus constructed a software AM radio transmitter utilizing an Arduino. The audio signal is supplied to the ADC input via a decoupling capacitor. A PWM output pin directly controls a capacitor-inductor circuit connected to an antenna. The schematic and firmware...
Arduino Projects
Powerful for its size and cost, and extremely easy to learn and use. A voltage monitor was added to a scooter to warn when the battery might need recharging, instead of waiting for the electric starter to fail. An Arduino...
Arduino on a prototype board
The USB to RS232 converter is called USB-2-bot and comes from another project. Any other converter would work as well, e.g. this USB-TTL-232-cable from adafruit. It has an ISP connector to program the bootloader and a serial connection used for...
Arduino Ping
The Ping is an ultrasonic range finder from Parallax. It detects the distance of the closest object in front of the sensor (from 2 cm up to 3 meters). It operates by emitting a burst of ultrasound and listening for...
Blinken lights circuit
Arduino consists of two main components: the hardware (the Arduino board) and the software (the IDE). The advantage of using Arduino is that circuits can be built and their behavior modified by altering the code instead of changing the hardware....
Arduino Differential Controller
Faulty readings from the DS18B20 temperature sensors used in tank thermometers were likely caused by the waterproofing method involving heat shrink and silicone. This situation provided an opportunity to enhance the code for better tolerance against erroneous readings. The tank...

Arduino Clock Based on PCF8563
This tutorial demonstrates how to utilize an Arduino to display the current time and date on an optional LCD screen and in the Arduino IDE serial monitor. A PCF8563 real-time clock (RTC) integrated circuit (IC) is employed to provide accurate...
