Engineers-Multi-Tool

yet another tool for electronics engineers to use on their workbench - planned to include Voltmeter, Ammeter, Component Tester, Serial Terminal, DAQ functionality, Waveform Generator.

A basic Arduino nano based portable device, having portable power, a basic display and circuitry to measure voltage, current, pulses, test components (Resistors, Capacitors, Transistors and more) and also be able to serve as a Serial Terminal and MORE.

Planned Features

• Handheld formfactor - credit card/gameboy/mobile phone sized
• Arduino based
• Input Push Buttons - 6 to 10 buttons via 1 single ADC pin
• Nokia Graphics LCD - Mono, Mobile LCD for Display
• Voltage Input - 0 to 50V or possibly, -50 to 50V Voltmeter (2x)
• Current Input - 0 to 500mA or even possibly 1A Ammeter (FUSED)
• Serial Terminal - Show incoming Serial data on screen (adjustable/auto baudrate)
• Sqaure Wave Generator - basic clock generator, upto 1MHz with adjustable Duty Cycle
• Pulse Counter - Basic Pulse stats - Freq, Duty Cycle, etc
• Component Tester - a variant of the SemiConductor Tester
• Battery Powered - Chargeable via USB
• Serial Connection with PC - A basic data acquisition app on PC Side - Windows/Linux

Suggest any other ideas that could be done..!

TODO

• Upload Schematic
• Battery Charger integration
• Serial Terminal implementation
• Write more TODO List items...!

WORK LOG

• Basic Circuit made on a protoboard
• LCD and Buttons Tested
• Simple Voltmeter 0.5 to 50V implemented
• Simple Pulse Generator Implemented with adjustable Freq/Duty
• Simple Menu interface implemented
• Integrate the Voltmeter, Pulse generator and Menu in one code

DONE before 10th of June 2015
