Car battery Indicator (BC548)
The operating principle of the circuit is very simple. The first LED D1 is placed in series with the resistor R2 and diode D4. An only be lit this LED indicates that the battery is ypofortismeni. For this reason, LED...
LED bar peak program meter display for audio
A vertical column of LEDs is configured so that as the audio signal level rises, an increasing number of LEDs illuminate. The LEDs are arranged in increments of 6 dB. The circuit features a fast response time and a one-second...
battery indicator circuit for the caravan
The i-TRIXX circuit is designed to prevent issues for individuals traveling in a caravan. It provides an early warning system through an illuminated LED, alerting users when the battery charge is low, thereby preventing the inconvenience of being unable to...
Woodstock HP-21 HP-25
The machine utilizes a 12-digit display consisting of 8 LED anodes controlled by an anode driver, and 12 digits managed by a cathode driver, which also scans the keyboard's 7 columns. The bus is simplified to 4 lines: two clock...
Voltage-monitor
When the battery voltage exceeds approximately 11 V, current flows through resistors R1, D1, and R2. The voltage generated due to the current flowing through R2 is sufficient to turn on transistor Q1, effectively bringing its collector voltage near ground...
LED Hat Display with Pong using an Arduino
Some time ago, a Pong game was developed as an initial microcontroller project using a 5G-7 LED display, but it was not pursued further. Recently, a hard hat was provided as part of a uniform for an engineering competition, prompting...
Advanced LED Temperature Indicator
This verified project provides an idea, circuit, and operation of the LED display temperature indicator. It features a digital temperature indicator utilizing a voltage-to-frequency (V/F) converter, along with various electronic projects.
The LED display temperature indicator is designed to provide a...
5 volt ttl voltage monitor
This device is designed to control a supply voltage of +5 V. It provides information signals at TTL levels, accompanied by an LED display that indicates whether the voltage is within the nominal value or deviates from it. The device...
Micropower double ended limit detector
The detector utilizes three sections of an L144 and a DC4011 type CMOS NAND gate to create a very low power voltage monitor. If the input voltage, Vin, is above Vhigh or below Vlow, the output will be a logical...
