I Made This Budget Multimeter Wireless! https://tube.loping.net/videos/watch/bc756f86-9cd3-42f7-9803-b5699a960fd2 ENOUGH! No more webcam pointing at my ANENG AN870 LCD to capture the reading. Let's make it wireless! This mod requires an ESP32-C3, RP2040 Zero, and HC-12 wireless modules, but it is so worth it!
