Digital Temperature Meter

Learn to make a Digital temperature meter using latest display I2C OLED. Only three parts is used and gives much better performance. It looks outstanding, better display due to OLED without requirement of backlight and can be read from distance. We have used LM35 IC as heat sensor. Arduino UNO as micro processor and OLED as […]

Using Fuse Tubelight

The circuit illustrated below can RE use your thrown tube light. which usually blinks in normal circuit. A high DC voltage has advantage to glow a a weak florescent tube light. A weak florescent tube gets black at one edge. At black end Positive voltage should be applied and can be marked as anode and […]

Touch Switch

Touch Switch Project Thief’s are attracted to expensive things when they come in our houses. We can protect our product or thing by making them touch proof or we can stop any unidentified persons entry in our house by making door and window touch proof. This circuit alert us when anyone come to stole products […]

Temperature Sensor

This project uses IC LM35 as a sensor for detecting accurate centigrade temperature. Linearity defines how well over a range of temperature a sensor’s output consistently changes. Unlike thermistor, Linearity of a precision IC Sensors are very good of 0.5°C accuracy and has wide temperature range. its output voltage is linearly proportional to the Celsius […]
