It is a very simple experiment for Arduino amateurs, kids and beginners. It needs two LEDs, one LDR (Light Dependent Resistor), one tactile switch and some resistors of different values..
With this project/application, you can make a light sensor dependent lamp. You can make a light sensor or dark sensor with this application. The light sensor of your Android smart.
Description: In this clap switch we use three different modules given below. It is necessary to make these three modules in order to make a clap switch. a. Dark sensor.
Description: LM358 is also one of the types of operational amplifier. LM358 consists of two independent, high-gain, frequency-compensated operational amplifiers designed to operate from a single supply over a wide range.
Here's a simple light activated police siren using light dependent resistor and NE555 timer. Before you make this project, I would recommend you to make the following projects. a. Light.
Here's a simple experiment with LDR and CD4093. This is just a modification of a previous project "dark sensor using 2 transistors". In this project, the CD4093 is configured in.
To make light operated switch, you need to know these circuits: a. Toggle switch b. Dark sensor using two transistors (more…)
To make a remote operated switch, you need to understand following circuits. I recommend you to make these circuits before you try a remote operated switch. (more…)
A dark sensor can be converted to a simple FM transmitter using the following components. This FM transmitter is very sensitive and it has transmitting range of 30 meters. (more…)
An automatic dark sensor can be made using a PNP transistor(BC557). (more…)
[vc_row][vc_column][vc_column_text]To make an object counter we can use a simple dark detector circuit and a normal calculator. Pole and NO (Normally Open) terminals of a relay have to be connected.
A multivibrator is an electronic circuit used to implement a variety of simple two-state systems such as light emitting diodes, timers and flip-flops. It is characterized by two amplifying devices.
A voltage divider consists of two resistances R1 and R2 connected in series across a supply Voltage Vs. The supply Voltage is divided up between the two resistances to give.
