In this post I have explained an innovative brake light circuit using speed detection of the vehicle which could be a motorcycle. The circuit implements an advanced brake light switch ON ensuring a much safer riding experience for the user. The idea was requested by Mr. Rayan. Circuit Objectives and Requirements I have an idea, […]
Newly Updated Circuit Projects:
Car Reverse Parking Sensor Circuit with Alarm
In this post I will show how to construct a car reverse parking sensor alarm circuit using arduino, ultrasonic sensor and 2.4 GHz transceiver module. This project can be add-on feature for your car if it doesn’t sport a build-in parking sensors. Introduction The proposed project has similar functionality as traditional car parking sensor has, […]
Solar E Rickshaw Circuit
In this post I have explained a simple solar electric rickshaw or E rickshaw circuit which can easily built by anybody at home and used with a locally fabricated vehicle. The idea was requested by Mr. Amit. The Design Selecting a BLDC In one of my earlier posts I presented an idea which could be […]
10 LED Tachometer Circuit Diagram
In this post I have explained how an accurate 10 LED tachometer circuit can be built using ordinary parts like IC 555 and IC LM3915. The idea was requested by Mr. Munsif. What is a Tachometer A tachometer is a device which is used for measuring vehicle engine RPM. Thus, it is basically used for […]
Bluetooth Car Ignition Lock Circuit – Keyless Car Protection
This circuit will allow the user to lock his car ignition using his phone Bluetooth, meaning the ignition can be locked/unlocked only through a specific code from the user’s cellphone Bluetooth. Overview In one of my earlier posts I have already explained how to hack a Bluetooth headset and use it for any desired switching […]
Ultrasonic Fuel Level Indicator Circuit
An electronic device or circuit which detects and indicates the various fuel levels in a fuel tank without a physical contact, through ultrasonic waves, is called an ultrasonic fuel level sensor In this post I have explained how to build a simple fuel tank level indicator circuit using Arduino and ultrasonic sensors. In every vehicle […]
