Description: Here’s a simple DIY clap switch circuit. The circuit is mainly composed of an audio frequency and a bistable trigger circuit. Q1 and Q2 together form an amplifier circuit. MK1 (electret microphone) accepts Clap/Audio signal and that enters to transistor Q1 through the coupling capacitor C1 and enters to Q2 base through collector directly after getting…
WTV020SD-16P music module is one of the hot topics in current days. WTV020-SD module can be used in automotive electronics (anti-theft alarm, parking sensor, GPS navigation systems, electronic dog, central locking), smart home system, home burglar alarm, medical instruments, the human voice prompts, music player, home appliances (cooker , rice cookers, microwave ovens), entertainment devices…
Here is a very simple breadboard power supply kit that takes power from a DC wall wart and outputs a selectable 5V or 3.3V regulated voltage. The .1″ headers are mounted on the bottom of the PCB for simple insertion into a breadboard.
The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators.
