Driving an AC high voltage and current load using an Infrared remote is very easy with this project. This is an open-source Arduino compatible hardware that is based on ATMEGA328 microcontroller, SSR (Solid-state Relay), Infrared Receiver TSOP1838, and analog input interface. We have...
Continue ReadingLead Acid Battery Voltage Monitor using ATMEGA328
Monitoring the voltage level of a 12V Lead Acid Battery (SLA) is easy and simple with this project. The board is made using an ATMEGA328 micro-controller and 12 x 5mm LEDs. The ATMEGA328 microcontroller senses the analog voltage on A3 Analog pin and drives 12 LEDs connected to digital...
Continue ReadingAnalog Light Sensor + Light Sensitive Switch using OPT101
You may have seen many light-sensitive switch circuits based on an LDR sensor. Usually, the sensitivity of the LDR based light sensor is poor. We wanted a very sensitive light switch hence we decided to make a circuit based on a light sensor rather than LDR. After a little research on...
