Simple Twi-light using white LEDs
This sunlight-controlled lamp utilizes a light-dependent resistor (LDR) as the sunlight sensor and comprises a total of 25 high-brightness white LEDs. Each row of LEDs is connected in series with separate resistors. The operation of the circuit is straightforward. During...
LED Voltmeter for Cars
The circuit is a comparator that can measure the voltage of a car battery in steps of 1 Volt. The voltage is determined after comparing the voltage of the battery, which is applied to the inverting inputs of amplifiers, with...
photoresistors servo and arduino
The movement of the servo is determined by the output values of the photoresistors. The impedance of these sensors changes with the amount of light incident upon them. The servo's position shifts towards the sensor that detects less light. There...
project crystal
This is the initial phase of an Arduino-controlled PWM RGB LED project, which incorporates distance and PIR sensor control along with a sleep mode feature.
The project utilizes an Arduino microcontroller to manage a Pulse Width Modulation (PWM) RGB LED, allowing...
Implementing Adaptive Brightness Control to Seven Segment LED Displays
An automatic brightness adjustment is a closed-loop system that has the capability to assess ambient light and adjust the brightness of the display accordingly.
The automatic brightness adjustment circuit operates by utilizing a light sensor, typically a photoresistor (LDR) or photodiode,...
twitterpop
After acquiring an Arduino and several 8x8 LED matrices, a project was initiated to effectively utilize these components. Concurrently, there was an increasing interest in Twitter and its API, leading to the development of a Twitter popularity meter. This system...
LED indication Integrated Circuits
The LB140 is depicted in Figure as a typical driver IC circuit for a five-digit LED level indicator. The BL1405 is commonly utilized in tape recorders for level indication.
The LB140 integrated circuit serves as a driver for five-digit LED displays,...
arduino Switch transistor with a low voltage and current
A circuit is being designed that utilizes a combination of switches and resistors to enable a microcontroller to identify which switch has been pressed based on the voltage read, and subsequently perform a switch-specific action. The proposed design incorporates a...
arduino yogurt maker
The crock pot is connected to a relay that can turn it on or off. The relay is controlled by a microcontroller based on readings from a temperature sensor (thermistor) located inside the crock pot. The objective is to heat...
