Review on 🔍 EEEEE UNO R3 Logic Probe & UNO R3: ATMEGA328P ATMEGA16U2 Digital Logic Tester | Arduino IDE Compatible by Justin Cage

As far as I can tell the logic probe only uses the microcontroller for power. I downloaded the "Blink" program from the sample library and it made the LED on the board turn on and off about once a second. If you place the tip of a logic probe on pin 13, it will show a logic level shift when you change which LED on the probe is lit. The tip is elastic to help maintain contact during probing. The logic probe plastic cover was made from 3 pieces of laser cut plastic with a paper protective cover that peeled off easily once you lifted an edge. The card shows the possibility to download the manual and software, but if you go to this site you will not find anything related to this product. So the product works as it should but lacks instructions or a good link to it. If you already know how to program and use Arduino, using it is not a problem.
