The flex sensor, also sometimes called as bend sensor, has two pins, one is P1 and the other one is P2, these two pins can be used to retrieve data from the flex sensor. The sensor acts more like a ...

It’s like Dark and light Detector circuit but this time we are using Arduino to get more control over light. In this circuit, we are making a Light Sensor using LDR with Arduino to control a bulb/CFL ...

It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot form a variable resistor, whose resistance varies depending on soil moisture. This variable resistor is connected in ...

Connect the A0 pin of the Arduino to the same column where the LDR and resistor is connected (Since the LDR gives out an analog voltage, it is connected to the analog input pin on the Arduino. The ...

Analog Read (Voltage divider for various 2 prong sensors (variable resistors: flex sensor, photoresistor, touch/pressure sensor)) dot211-any-variable-resistor-sensor.ino: Change the Resistor amount ...

The circuit of Arduino-based shadow alarm is shown in Fig. 1. It consists of an Arduino board, power supply, light-dependent resistor (LDR) sensor, buzzer, relay driver and a few other components.

If our example resistor ended in gold (orange, white, black, gold), its 39 Ohms value could be five percent higher or lower. For a possible minimum of 37.05 or a maximum of 40.95.
