5 Channel RF relay control circuit 433mhz RF module set based on PIC12F675 microcontroller IC can be used (I used 434mhz module set, no problem) Depending on the RF module quality and the antenna used, it can remotely control the relay between long distances and can be used for turning on and off various devices…
Electronic combination lock circuit or Combination door automatic LCD, LED Display etc. It is simpler and easier to implement than systems with indicators. User password can be changed with administrator password. The heart of the combination lock circuit is the PIC12F675 microcontroller. For password entry, button or old telephone keypad is used, but I designed…
The speech module made with PIC12F675 24C512 Eeprom and LM386 integrated used to strengthen the voice signal, the voice warning circuit is set up with very little passive material. Warning, security, etc. can be used in projects. Its most common use is an electronic voice alert system to remember the “open door” or any action.…
The combination lock circuit displays the information and settings entered from the keypad built on the PIC18F4620 microcontroller on the LCD screen. All user password information settings are kept in the memory of the PIC18F4620 keypad is connected to the microcontroller via the 74C922 IC. Circuit description; An apartment lock system where the administrator can…
The control card made for the transformer winding machine can control the winding from 0 to 99.999 turns with 5 steps. You can use common cathode or common anode Led display. 6 buttons are used to control functions. The heart of the circuit is the PIC16F628 Microcontroller IC. The set number of rounds is saved…
A 2X16 LCD screen is used to display the data based on the weekly timer circuit PIC16F628A microcontroller and the DS1302 real time clock IC. There are different software for using 1.7 Channel without changing the PCB drawing. Relays 12V 10A Clock, calendar, 4 buttons are used for on-off settings of relays. The current drawn…
PT2240, PT2262, HT6P20B RF Transceiver ICs were cloned as software and application circuits were made with microcontroller. Clone circuits may be higher in cost, but it is a very good resource in terms of software. It is very difficult to put the working system of ICs such as PT2240, PT2262 into software. HT6P20B PT2240 PT2262…
The water sensor is used in various devices in factory, automation, etc. used very often in their work. Mainly for automatic water tank filling, irrigation, heating, control and more. etc., in general, sensors are used where there is water. The use of a spark plug as a water sensor is not new. Some manufacturers even…
The melody horn circuit is based on the PIC16F1827 microcontroller. The circuit can be connected to 2 horns with double relays. Relay is used for horn control. Relays 12V 10A power snail horn or similar can be used. There are 3 melodies, the first is John carpenter the end, the others are rhythmic. If it…
BEKA-MAX Type S-EP 4 pump is used for central lubrication of various mechanisms and equipment units. BEKA-MAX Since there is no IMS 559. 392 integrated in the original pump card, the author has made a clone pump control circuit using a PIC16F628 microcontroller. There is a pcb drawing prepared with the source Mplab asm and…
