ALPHANUMERIC LED DISPLAY PROJECT

  
A tiny sandwich flag connected perpendicular to the motor spindle aids observation of how long it takes to complete one full rotation. This worked initially, as each burst from the capacitor barely moved the flag 1/4 of a rotation. As the circuit variations became more efficient and powerful (the capacitors values became larger), a single burst provided rotational speed faster than a human can count. I took a huge diversion and built a counter circuit. A pushbutton (SW1) was necessary for manual testing, although an infrared interrupter pair would eventually provide input when connected to the BEAM engine project.
