The TSOP17XX series ICs are special infrared sensor devices built for responding to specific range of infrared frequencies and convert it into an electrical pulsed output. It thus features a foolproof immunity to other forms of IR signals. Due to this specific center or band-pass operating frequency of a TSOP17XX, it becomes difficult to use […]
Newly Updated Circuit Projects:
Make this Digital Temperature, Humidity Meter Circuit using Arduino
In our previous article, I have explained how to interface temperature humidity sensor with arduino and read out displayed on serial monitor of arduino IDE. In this post I have explained how to display the reading on a 16×2 LCD display for the proposed digital temperature/humidity meter using Arduino. Introduction This project may be used […]
Earth Leakage Indicator Circuit for Detecting Current Leakages in Ground Wires
A simple earth leakage indicator circuit discussed here can be used for getting some very useful results regarding current leakages from an appliance body into the earth pin. The idea was requested by Mr. SS kopparthy. The circuit of the proposed earth leakage indicator is shown in the figure below. Each such unit may be […]
AC Phase, Neutral, Earth Fault Indicator Circuit
The circuit explained here will provide LED indications and show if there’s a possible fault in the wiring of your home AC Phase, Neutral, and Earth connections. The idea was requested by Mr. SS kopparthy. Technical Specifications sir, very good morning. I thank you for your help. I further wanted you to consider a circuit […]
Clap Operated Toy Car Circuit
In this post we study how to make a simple clap operated toy car circuit using a clap switch circuit and a MIC amplifier, to control its forward and reverse movements, in response to the claps of the user. The idea was requested by Mr, Zeeshan. This clap operated toy car is will move in […]
Fishing YoYo Stop-Motion Switch Circuit with Indicator
In this post I have explained a stop-motion switch circuit or a strike indicator for aiding fishing yo yo applications. The idea was requested by Mr. Mike. Technical Specifications (kindly bear the long discussion) Hello Sir, My name is Mike. I am the one requesting help with this stop-motion switch from the “Homemade Circuits” Blog […]
