Electronic bination Lock Circuit Description A simple electronic combination lock is designed using IC LS 7220. This circuit can be used to activate a relay for controlling (ON & OFF) any device when a preset combination of 4 digits are pressed. Simple Key code lock switch circuit using IC 4017 ... This is a key code lock switch circuit, type of electronic circuit. To replace a conventional normal key switch, without inserts keys. But you can press the number code instead of unlocking keys. We do not need to carry a load key, and do not worry about your keys are lost. We just must remember to commit to code only. Electronic key lock This circuit diagram it is a very simple electronic key lock that can be used for alarm systems or other devices that can be activated by an electronic relay . Electronic Locks Circuits Hobby Projects Electronic Locks Circuits and Tutorials This circuit can be used to operate an electric strike or an electromagnetic lock on a door. It is not the door being opened closed, but a small electromagnetic strike which unlocks the door. The opener has the following features currently programmed in software Electronic Key Circuit electroschematics Based on CD4017 and logic gates this electronic circuit switches on a relay if you press four keys in the correct sequence, and backs to the start condition by pressing any key. Once the circuit is supplied the first output of the counter is on and sends the high signal to one input of the CD4081 first gate. Simple Code Lock Circuit electroschematics This simple code lock circuit described here is of an electronic combination lock for daily use. It responds only to the roght sequence of four digits that are keyed in remotely. If a wrong key is touched, it resets the lock. The lock code can be set by connectiong the line wires to the pads A, B, C and D in the figure. For example, if the code is 1756, connect line 1 to A, line 7 to B, line 5 ... Keyless Lock Electronics Project Design Automotive Keyless Lock. Keyless Lock Most vehicles today have remote controls with two buttons that control the locking and the unlocking of the doors of the vehicles. 200 Best Electronics Mini Projects: Circuits, Working ...
