Protecting Microcontroller Input Pins from Soft Power Switch
A soft power switch for a microcontroller is designed such that a momentary switch can activate the circuit, including the microcontroller. When the switch is pressed a second time, the microcontroller is capable of shutting itself down after executing necessary...
The power indicator circuit
The ACER PM02 MP4 machine features a voltage status indicator circuit. When power is supplied, a red LED illuminates, indicating that the device is powered on. Upon entering operational mode, a green LED lights up.
The voltage status indicator circuit serves...
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...
turret diy
For maximum mini-security, this RC Tupperware Turret delivers a formidable deterrent against food theft. While it lacks motion sensors, potential food thieves will think twice before attempting to swipe baked goods. This 11-hour project, designed by Chris of PyroElectro, emphasizes...
Battery operated mini night lamp
This circuit is designed as a low-power LED night lamp that automatically switches off during daytime. The CMOS timer IC TS555CN is configured as a square wave generator operating at approximately 5 Hz. The output voltage from the IC is...
DSLR Remote Control
Information and resources on remotely using a DSLR camera, primarily utilizing Arduino-based solutions.
The use of Arduino-based systems for remotely controlling DSLR cameras has gained popularity among photography enthusiasts and professionals seeking to enhance their shooting capabilities. These systems typically involve...
4-Channel Thermocouple Input Arduino(TM) compatible Shields and Boards
This is a complete standalone system compatible with Arduino Uno, which will be fully assembled, tested, and programmed prior to shipping. Users can select from various TC4 applications to be pre-programmed into the board. For those who wish to utilize...
Electronic dice with 7 LED
This project takes advantage from -HOLD input, which is connected to push-button P1. As long as the -HOLD input is low, truth table's timeouts have no effect because this input serves to disable any state change provoked by timers. The...
8 LED`s Audio VU Meter
This circuit uses two quad op-amps to form an eight LED audio level meter. The op-amp used in this particular circuit is the LM324. It is a popular IC and should be available from many parts stores. The 1K resistors...
