Arduino Based GPS Digital Clock Circuit

Last updated on 23 September 2025 by Admin-Lavi Leave a Comment

Normal digital clock use RTC chip or manual setting. Problem is RTC needs drift and reset. But here Arduino Based GPS Digital Clock Circuit solves the problem. GPS talk with satellite and always give exact time. Arduino read GPS time and show on LCD. So clock is never wrong, as it always auto update from […]

Long Range IR Transmitter Circuit

Last updated on 25 July 2025 by Admin-Lavi Leave a Comment

Compared to basic circuit this Long Range IR Transmitter Circuit can send IR light farther using easy parts. Main idea is to make IR LED blink light in pulses. Most IR receivers catch specific frequency made by IC 4047. Using more LEDs together or stronger LED gives more IR light, so with better range. This […]
