Carbon monoxide alarm circuit, which detects using the MQ-7-CO Sensor, operates on the PIC16F88 Microcontroller, the operating voltage is 12v dc, it detects carbon monoxide and pulls the 12v relay in the circuit according to the level, whatever is connected to the relay (siren, lamp, etc.) is working. Carbon Monoxide Alert Carbon monoxide is an…
Fast charging circuit with PIC16F88 microcontroller can work with dc voltage between 7-30 volts. PIC16F88 used for control can fast charge NiMH and Nicad batteries whose supply is provided with LM317T. When the batteries are full, automatic charging is interrupted. There is heat protection with thermistor. The highest charging current is 2.5a. Quick Charger for…
For this Timer circuit, there is information about the operation of the system, how to use a circuit designed for the car called “Adaptive Turbo Timer”, but in English 🙂 still, the source codes are pcb and so on. Since it has drawings, it can give inspiration for different projects that are worth sharing. Adaptive…
PWM Motor control circuit MC34063 switching dc dc regulator is used to supply pic16f88 microcontroller 4 mosfets are driven with PIC (IRF1405) EMF control is also made with PIC for better speed control, there is also a 4 digit display indicator pic16f88 works with 8mhz 12V 24V Motor Speed Control circuit motor It consists of…
