Pressure Activated Light-Up Umbrella using an Arduino

Inspired by a previous project, a unique design was developed that incorporates an umbrella capable of playing musical notes when pressed. For additional information regarding the 4051 chip, which functions as a multiplexer or demultiplexer, refer to resources available on...

isolated mains power monitoring arduino

A mains (220-240VAC) power monitoring circuit has been sought for interfacing with an Arduino. While the OpenEnergyMonitor solution employs a transformer for isolation and measurement of mains voltage, it has been noted that the transformer does not couple effectively to...

Perfect Pitch Circuit

Perfect Pitch, which is based on the 8751 microprocessor, is an affordable and straightforward instrument tuner and frequency counter that features a built-in headphone amplifier and a visual metronome. Perfect Pitch converts the audio signal from an instrument into a...

Arduino-based AVR High Voltage Programmer

Fortunately, my trusty Arduino came to the rescue. I created an Arduino-based AVR programmer that uses the high voltage programming mode and can fix pesky fuses like RSTDISBL. The Arduino has just enough IO to implement the entire HV protocol...

Auto-Fill Valve with Arduino

Part fill valves are commonly utilized in rainwater tanks. The valve activates when the water level in the tank drops to a low position. Part fill valves play a crucial role in the management of water levels in rainwater harvesting systems....
