Project #1: Part 1: Motor Control Circuit Objective –To control a DC motor at 12V/1Amp that will run at variable speeds, manually, or by computer. –Control of mirror movement –Using the NAND,555, One Shot, and Inverter
Final Design of Control Circuit When manual is in use computer is locked out and vice versa
Project #1: Part 1: Success! Project #1 Part 1 was a success and currently moves mirrors within the new spectrometer
Project #1: Part 2: Pulse Box construction for Spectrometer #3 Objective –To build a pulse box that could generate a sequences of pulses.
