This is a square wave pulse generator module based on the ubiquitous NE555 timer IC. The module can be powered from a wide power supply range (4.5 to 12V) and will produce a continuous square wave output between 15Hz to 24KHz which can be set by on on-board multi-turn potentiometer. Useful for applications where an approximate frequency clock source is required such as for stepper motor step generation tone generation etc. Read our article to know more about 555 timers

Power relay delay pull. Specifically: 12v power supply to the relay, the relay will not immediately sucked and status relay outputs are normally open disconnected public,normally closed and public conduction,wait until the delay 1-10s (adjustable),the relay suction and, this time, the relay output status is: normally open and public conduction,normally closed and public disconnected; as long as uninterruptible power module, this state will remain.

WiFi connections are sometimes a must in your project. It really gives it the IoT identity and power to send/receive messages/commands from anywhere using only an internet connection. Although you might think it’s hard to add this option to your project, a simple google search can prove the opposite. Before […]
