Automatic Temperature Controlled Fan
Automatic Temperature Controlled Fan control the speed of fan according to change in temperature using temperature transducer AD590 and op-amp LM324 circuit dia...
Laser Activated Switch
This circuit is built around a 555 timer using very few components. Since the circuit is very simple, even a novice can easily build it and use it as a controll...
pid controller Building a temperature-controlled water bath
I have no experience whatsover with building controllers and have no clue on how to start. I don`t want to spend to much money on the project (< 100 ‚¬) thus...

resistance Replicate thermistor behavior for second sensor
An R/C electric motor that has a 10K thermistor sensor built into it, which is connected to a speed control that has basic thermal protection. I would like to b...
Is there a simpler solution for highside current sensing here
The loads (2 or more solenoids in parallel) share a 12V supply and are individually switched to ground through the car`s ECU. I need to detect when any one of t...
potentiometer Making an adjustable resistance
Actually this part of the circuit is isolated from any other component (except via 5v & ground). Other than that, you can find LEDs and a shift register, but I ...
Zero crossing detector: do I really need the 7W resistor
Provide zero crossing detection to my controller. Using the schematic below, I managed to generate square wave signal, representing positive v/s negative half-p...
avr Piezoelectric Sensor and the ADC
The reason being is that I would like to use the sensor as a force sensor. I noticed that the harder I press it, the higher a voltage it delivers (but for a ver...
arduino Sharp IR distance sensor outputting consistently high voltage
A project with two distance sensors that signal an Arduino to operate a servo motor when an object comes into range. This currently works well, except that the ...
instrumentation amplifier How to Read Wheatstone Bridge negative voltage with Arduino
A half bridge setup with strain gages and a INA126 to amplify the voltage. I can read the voltage fine when the lever is bent one way, but when beding the lever...
