Furthermore, circuit is good for beginner, easy to learn 555 timer and sound making. Circuit Working: Parts List: Components Values […]
Easy DIY Timer Alarm Circuit with 555 IC
IC 555 is very popular and useful chip in electronics and it works in different modes with bistable, astable and monostable. Here we used IC 555 in monostable mode to make a Easy DIY Timer Alarm Circuit with 555 IC, also we can set time and after that the buzzer or alarm will ring. In […]
Simple 60 Second Timer Circuit using IC 555
Simple 60 Second Timer Circuit using IC 555 controls timing in many electronic applications, also this circuit uses the 555 timer IC, a popular chip that engineers and hobbyists widely use for timing functions. Press push button and LED turns ON for about 1 minute. Also, this circuit is good for delay lights, fun projects […]
Arduino 2-Step Programmable Timer Circuit with Independent Output Delay Adjustment
This project for Arduino 2-Step Programmable Timer Circuit with Independent Output Delay Adjustment uses Arduino microcontroller to make simple timer. Not like normal timer with two outputs as this one uses only one output and it also switch between two states and each state have delay which we can change for different use. Arduino Code: […]
Power ON Delay Circuit
To begin with, Power ON Delay Circuit using IC 555 give time gap between power ON and circuit starts. When trigger comes, IC 555 work in monostable mode and give one output pulse for set time; furthermore, resistor R1 and capacitor C2 make timing part for delay. When the circuit is OFF, the output stays […]
