This project make digital thermometer using IC LM35 sensor and Arduino. Arduino reads voltage from LM35 and changes it to temperature number. People use thermometer for long time to check temperature. Temperature show on small LCD screen for easy see. With Arduino we can build thermometer that show real-time temperature on screen. It can be […]
Interfacing a 7-Segment Display Circuit with Arduino UNO
Interfacing a 7-Segment Display Circuit with Arduino UNO is small electric part which shows numbers. It have 7 LEDs inside and makes shapes for numbers and some letters. We can connect it to Arduino and then it tells what number to show. This article teaches how to connect 7-segment to Arduino UNO and show numbers. […]
DC Motor Speed Controller Circuit using Arduino
This project for DC Motor Speed Controller Circuit shows how to control DC motor speed using Arduino, MOSFET and potentiometer. Arduino make PWM signal to control MOSFET gate. MOSFET work like switch and control voltage to motor and changes speed. Arduino speed controller is simple and with low cost. It can control motor, light and […]
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. It switch between two states. And each state have delay which we can change for different use. Circuit Working: Parts List: […]
Battery Status Indicator Circuit using Flashing LED
Battery Status Indicator Circuit using Flashing LED is an easy to make project. Circuit uses BC547 and BC557 transistor, some resistors, capacitors, one diode and one LED. LED show battery condition by blinking light. It work with 6 to 12V battery and it is easy way to know battery health and it ensures it works […]
Simple FM Radio Jammer Circuit
Simple FM Radio Jammer Circuit make signal to block normal FM radio. It send noise or fake signal on same frequency so real FM signal get disturbed. Main parts: Transistor work like oscillator and make RF signal. Coil and capacitor set the frequency of this signal. Change trimmer capacitor to change jammer frequency inside FM […]
