This is an interesting project where the intensity of a lamp can be controlled by touch. Most lamps only have an on/off switch. They don’t have any regulators to increase or decrease the intensity of lighting. Having such a built-in feature is available for some expensive lamps. But the same can be achieved without emptying […]
This is a simple electronic project suitable for everyone. This project is about making a LED bar graph thermometer using two ICs, one for the sensor. What is a bar graph thermometer? A bar graph thermometer is one that shows temperature reading using an array of LEDs instead of a digital numerical output. Here this
A simple electronic combination lock is designed using IC LS 7220. This circuit can be used to activate a relay for controlling (ON & OFF) any device when a preset combination of 4 digits are pressed. The circuit can be operated from 5V to 12V. The LS7220 IC is a MOS digital lock IC that
