As you know, microcontroller boards have many pins, and wiring them to other components or keeping track of the different wires sometimes is not easy. Today I show you how I do it. Most of the tricks work for all microprocessor boards like the Arduino, the ESP8266 or the ESP32. And with a unique feature of the ESP32, we can optimize a little more.

In this video, we will cover the following tips and tricks:
1. Use colors
2. Connect ground first
3. Pre-fabricated wires
4. Use empty Dupont shells
5. Use the right pin order
6. Not enough Ground or VCC connections on our development boards
7. Super Glue can help sometimes
8. Crimping you own wires
