Step 1: Introduction The PV applications could be grouped according to the scheme of interaction with utility grid: grid connected, stand alone, and hybrid. PV systems consist of a PV generator (cell, module, and array), energy storage devices (such as batteries), AC and DC consumers and elements for power conditioning. The most common method uses […]

RS232 Connection Notes See the RS232 reference to determine the wiring for either a 9-way or 25-way female D Type “sub-miniature” connector. RTS and CTS are connected together. RXD is used to steal a negative supply. You may have to connect DSR and DCD to DTR if you are using the Arbiter hardware with other software.

Introduction: This describes my original design dual channel quantizer inspired by Chris List’s ARP Style CV Quantizer design. My new implementation is an intelligent design that exploits the programmability of a Microchip PIC16F84. It will quantize voltages in 1/12 volt (semitone) or 1 volt (octave) steps from –10V to 10V. Quantization time is about 2ms

The Button Code is a system that allows a single button to act as a keypad. The user enters a 4 digit code into the system using button taps. The button can be placed where the public can access it since like a keypad there are many combinations to keep guessers from activation the system.

Voltmeter Ammeter is a great kit to measure voltage and current at the same time. It measures 0-70V or 0-500V voltage with 100mV resolution and current from 0 to 10A. It’s a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. Kit uses PIC16F876A microcontroller
