The TSL235R light-to-frequency converter outputs a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance). The device has been temperature compensated for the ultraviolet-to-visible light range of 320 nm to 700 nm and responds over the light range of 320 nm to 1050 nm.
The TSL235R can be powered at anywhere between 2.7 and 5.5V, and will typically pull about 2mA of current. It comes in a simple, 3-pin through hole package. No external components are necessary to use the converter, and the digital output allows direct interface to a microcontroller or other logic circuitry.
High-resolution conversion of light intensity to frequency with no external components
This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5x2.1mm, center-positive male barrel jack. If you need to connect bare wires to a barrel jack on an Arduino or a development board, this might be the simple solution.
This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5x2.1mm, center-positive female barrel jack. If you have a power supply with a barrel jack and want to plug it into a breadboard, this might be the simple solution.
This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit\'serial number etched into it - allows for a huge number of sensors to be used on one data bus. This is a wonderful part that is the corner stone of many data-logging and...
The TLC5940 is a 16 channel PWM unit with 12 bit duty cycle control (0 - 4095), 6 bit current limit control (0 - 63), and a daisy chainable serial interface. It is handy for expanding the number of PWM outputs available.
Be the belle of the ball with the NeoPixel Jewel! We fit\'seven of our the tiny 5050 (5mm x 5mm) smart RGB LEDs onto a beautiful, round PCB with mounting holes and a chainable design to create what we think is our most elegant (and evening-wear appropriate) NeoPixel board yet.
This is a simple, but extremely handy board to adapt the common 10-pin ISP programmers to the smaller 6-pin ISP connections. We also designed in a 6-pin inline connector so that you can insert this board directly into a breadboard! Good for the AVR programming tutorials. Pin 1 indicators indicate how the AVR-PG1 and PG2 should be oriented.
Round and round and round they go! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6" (66mm) outer diameter. The rings are \'chainable\' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the...
Ready to add audio to your next project? This small breakout board couples a small electret microphone with a 100x opamp to amplify the sounds of voice, door knocks, etc loud enough to be picked up by a microcontroller\'s Analog to Digital converter. Unit comes fully assembled as shown. Works from 2.7V up to 5.5V.
Electronic brick of relay can be connected to digital I/O port, when the input of S port is low level, relay will be under Ôdisconnect\'state; when the input of S port is high level, relay will be under Ôconnect\'state. It can be connected in series to the LED lights, buzzer or even the loop of a small lamp so as to control the state of the switch.
