LEAP: Little Electronic and Arduino Projects

Build and test a simple 2-transistor code practice oscillator

Design and test a basic 9v to 5v step-down regulator circuit using the MC34063A.

Building an LDR-controlled relay kit with hysteresis/delay for on and off transitions (LM393 comparator with RC-dampened inputs)

Testing a small 3V, 3-digit LCD panel with an example of driving the mulitplexed LCD (1/4 duty, 1/2 bias) with an Arduino/ATmega328 sketch.
