2016年9月22日 · (precision measuring) <> (Arduino 10-bit ADC + breadboard + long wires + non-ratiometric sensor + wall wart power supply(?)) PS: judging from responses, the problem …

2023年1月5日 · For the measurement of the transparency of differently structured glass I want to measure the change of lightintensity of a HeNe Laser shining through the glass, using a …

2014年11月19日 · Hi everyone, I am currently working on a project which utilises a silicon photodiode - for reference it is the BPW21R and the link to the data sheet is this: The …

2014年10月15日 · Hi guys, I am relatively new. I am trying to use a photodiode ( 2 pins) to read a voltage depending on the amount of light hitting the photosensitive surface. I have tried to use …

2018年2月7日 · Hello, I have 10 LEDs with different colors: blue, red, green, orange, yellow and each LED has a different Imax: 2mA, 5mA, 10mA, etc... up to 120mA (the last one). The task …

2023年10月29日 · I am very new to Arduino and I need to create an embedded system that measures light intensity by using a primary sensor as a solar panel and a backup sensor as a …

2013年6月22日 · I want to connect the photodiode to an Arduino (the grand-plan is to add an ir diode and build a distance sensor). I understand that photodiode produce current, and it …

2015年4月30日 · Currently I am trying to work with a photodiode(SFH 203) that is supposed to detect very small amount of light. Using the digital of an arduino the photodiode cannot turn …

A transimpedance amplifier works by converting a current (the signal that comes from the photodiode when a photon knocks some electrons loose) into a voltage through the feedback …

2013年3月2日 · Ok everything is working now XD. Attached is a picture of my setup if it's not clear enough: the solar cell is on (positive side) d11 and (negative side) d13, the 10k resistor is …
