My son wants to know more about MOSFET. I recommend trying to create simple Time Delay circuit using MOSFET,easy to make and long time and less parts than normal transistor. because working with voltage gate.
Category: Controls & Timers
All controller, motor speed driver,switches,timer,sensor,and more : Timer switches • DC motor speed control • Delay timers • Light switchs • SCR controls • Light dimmers • Infrared remote control system • and more…
This is first mini emergency light of my son. It is very small, use LED display when power outage,use transistor instead relay use AA battery charger.
This is IC 4060 Timer circuit. When rises time that is set, Suppose set 5 minutes time. after all time to 5 minutes. the circuit will emit a sound of buzzer once.
This is timer circuit uses a 555 IC timer. it small,compact,portable. For the snooze alarm by buzzer when some 5 to 30 minutes. It make easy with pcb layout
Today we will as push button switch as toggle switch using arduino . When we press the button "on" it will store status "on" hold, although, we will release. Then, we press it again it will "off" and store status "off" as well.
