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…
I made a visually different version of the 10 channel 100 Led Spectrum Analyzer circuit that I used in the 2.1 sound system. The filter quality of the Led Spectrum Analyzer is around 6, and the middle frequencies are 31Hz, 62Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz and 16kHz. J5 on the circuit changes…
The author said to work in the form of “Sea Breeze” for the fan, but I thought of saving electricity. The speed control circuit of the fan works intermittently in the form of a light breeze instead of working continuously. The MAC16N 16A 800V triac is controlled with the MOC3082 Triac Driver Optocoupler based on…
The inverter is fed from a single phase with 230V alternating voltage with a power of about 400W. The output gives a 3-phase voltage of 3x230V. Inverter diagram, dsPIC33FJ32MC102 software, Kicad PCB design are attached. Main control IC FNA41560. There is a PFC power factor correction circuit at the inverter input, which ensures that the…
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…
ESR meter is a device used to measure the equivalent series resistance (ESR) of capacitors. Built on the PIC16F690 microcontroller, the previous version uses PIC16F873A) The ESR meter circuit is very small in size and its features are very good. In the ESR Meter Milliohmmeter project, the PIC16F690 program was written in MikroC. Proteus drawing,…
Siren circuit is built on the PIC12F675 microcontroller, and the outputs of the PIC12F675 are powered by a 6-transistor bridge amplifier. Considering that the resistance of the siren is 2 Ohms, the output power is about 25W. According to the author’s explanation, since the transistors in the Bridge work in switch mode, they do not…
