RS 422 Compatible Indicator
The design involves creating a circuit and programming for a stepper motor controller, developing a speed-controlled DC motor circuit for the propulsion system of the project, and designing a navigation system using a MEMS accelerometer circuit. This section deviates slightly...
Robot Motor Control Schematic
The schematic for controlling the motors is divided into three main sections, each serving a distinct function. The primary components featured in the schematic include the PIC 18F252 microcontroller, the SN754410 motor driver, and 2N2222 transistors. At the top of...
Microcontroller Relay Driver and Interface
Many microcontroller designs typically integrate various interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs.
Microcontroller systems are versatile platforms that facilitate the integration of multiple interfacing methods to interact with various peripherals and...
Silent Radio LED sign to Arduino
The project addresses a brightness issue with the LED display. The original design using a 4017 counter was ineffective because it lacked the capability to turn off the display while updating the shift registers. Consequently, the decision was made to...
arduino clock
The Arduino displays the time and date on an optional LCD and in the Arduino IDE serial monitor window. A PCF8563 real-time clock (RTC) integrated circuit (IC) is utilized to generate the time and date. The time and date can...
Current amplification for driving stepper motor
In the search for stepper drivers, the ULN2003 chip was discovered, which facilitates motor operation with minimal circuitry through the parallel port of a PC. However, the current output from the ULN2003 is limited to 500mA, resulting in low torque,...
Robo Atmega328p project
This project was designed to introduce a friend to microcontrollers and circuits using various functionalities and spare parts. A PS2 numpad was utilized as the key entry mechanism, which was found at a thrift store and included the necessary connector....
Driving Stepper
M1 is a stepper taken from an old disk drive. There are five pins, i.e., common, coil 1, 2, 3 and 4. Resistance measured between common pin and each coil is about 75 Ohms. Driving current for each coil is...
arduino on breadboard
On the Uno boards, there is an integrated circuit (IC) that functions as a USB to serial converter, enabling programming and communication with the Arduino from a computer. This IC is a surface-mounted device (SMD). The R3 version utilizes an...
