GSM Remote Control Gate Control Schematic
Power is supplied by continuous voltage, which is not always stabilized, applied to PWR + and - at a value between 5 and 32V. This voltage is filtered at the bottom by a diode (D1) that protects against polarity inversion,...
control electric appliances
This circuit can power on or off various electric and electronic devices such as ADSL modems, personal computers, water boilers, water pumps, garage doors, lights, and more. Additionally, it allows for monitoring the status of eight switches, which can be...
Remote Controlled Alarm circuit
A remote-controlled alarm circuit utilizing the TSOP1736. This circuit involves routing an electric cable to connect a calling bell switch near the bed of an elderly individual.
The remote-controlled alarm circuit designed with the TSOP1736 is an innovative solution for enhancing...
Jet
The microcontroller is able to make about 7000 complete line-following decisions per second, which is almost 7 decisions per millimeter when the robot is going full speed. By upping the clock, unrolling loops, and removing my wireless debugging and extraneous...
repair microcontroller circuit
The difference between these two ICs. A microcontroller is a specialized type of microprocessor designed to be self-sufficient and cost-effective, while a microprocessor is typically intended for general-purpose use, such as in personal computers (PCs). The microcontroller integrates several useful...
Microcontroller-based automatic night light circuit
While discussing an all-linear automatic night light circuit, it was mentioned that an MCU-based Automatic Night Light Controller (ANLC) was being tested. The firmware has been tweaked since then. Recently, the sensor was installed outdoors and connected to control 220VAC...
pc based digital ic tester
Check the following ICs: 7400, 7402, 7404, 7408, 7432, 7486. A Visual Basic program is utilized to display the results on the PC. The microcontroller AT89S52 receives the IC number from the PC, verifies the logic gates with the truth...
Eight-digit-microprocessor-display
The display interface utilizes the ICM7218A/B in conjunction with an 8048 family microcontroller. An 8-bit data bus (DBO/DB7-IDO/ID7) facilitates the transfer of control and data information to the 7218 display interface during successive WRITE pulses. The mode input pins on...
Simple Remote Control Tester
The circuit biases the BC558 transistor, causing LED D1 to flash in response to signals from the remote control. The preset resistor in the circuit sets the sensitivity level.
The circuit utilizes a BC558 PNP transistor, which plays a crucial role...
