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; also Arduino make PWM signal to control MOSFET gate. After that, MOSFET work like switch and control voltage to motor and changes speed. Arduino speed controller is simple and with low cost and it can […]
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: […]
Battery Status Indicator Circuit using Flashing LED
Battery Status Indicator Circuit using Flashing LED is an easy to make project, as the circuit uses BC547 and BC557 transistor, some resistors, capacitors, one diode and one LED. LED show battery condition by blinking light and it work with 6 to 12V battery and it is easy way to know battery health and it […]
Simple FM Radio Jammer Circuit
The Simple FM Radio Jammer Circuit generates a signal that blocks normal FM radio transmission; additionally, it transmits noise or a fake signal on the same frequency, thereby disrupting the real FM signal. Main parts: Furthermore, transistor work like oscillator and make RF signal and coil and capacitor set the frequency of this signal, also […]
