Week four (20/02/24)

 Final circuit diagram



 A new LCD display was found, and this was used instead and worked fine, however, this LCD required different circuitry to connect it, so this was done.

 

The algorithm for calibrating the machine was changed, we hit each LED 20 times and measured the average ratios of sensor 2 and sensor 3 compared to sensor 1. These ratios could then be used to estimate the location where the hammer hit the acrylic sheet in future hits.

  Week three (13/02/24) Initial circuit diagram Breakout board for the LCD display arrived (this was required because the pins on the LED display were closer together than the tracks on Veroboard).   Completed transferring the circuit to Veroboard, most of the circuit was housed inside a small box. We made a hole in the back of this box for all the wires to go through.   LCD display did not work, the cause of this is unknown.
