In this video we do the 18th project from the Maxitronix Sensor Robot 20 (20in1) Electronics Project Lab Kit: Rain Detector.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to see the 1.6 kHz square wave from our astable multivibrator.
We use the UNI-T UTi260B Thermal Imager to watch the thermal effects of the circuit. We see both the 1K resistors in the astable multivibrator get warm, but only the activated side of the bistable multivibrator gets warm.
We use the Fluke 17B+ Digital Multimeter to buzz out the circuit looking for mistakes.
We use the Riden RD6006 Bench Power Supply to provide 9V for our circuit. I make a mistake and connect it the wrong way around to begin with!
