Soldering Projects Board #2
DC input - polarity and
overcurrent protected.
DC outputs - switched and variable. Test with DC motor on PCB.
Astable multivibrator - flashes LEDs, with variable ON times, and drives an electronic switch to power external devices. Test with DC motor.
LC oscillator - produces a 4 kHz sine-wave and other waveforms. Test with piezoelectric transducer on PCB.
Experimenting area - ideal for simple IC circuits. NE555 timer circuit suggested and detailed.
