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

This product is an electronics kit for building a logic analyzer for use with the Arduino UNO board. It has 32K of memory and can be connected to a computer via USB for firmware and power. The logic analyzer can detect high voltage on a red light (2 to 5V) and low voltage on a green light (0 to 0.8V), and high resistance (or high resistance or just a trip) on a blue light. The board that comes with this kit is compatible with the Arduino IDE and I used their publicly available blink code example where pin 13 goes high for one second and then goes low for another second. They all work fine.
