#221 Arduino nRF24L01+ Simple Trigger Wireless ⚡ Project (Update) with EasyEDA

A more detailed walk-through of a simple Arduino/nRF24L01 switch-triggered module. JLCPCB Only $2 for PCB Prototype any colour https://jlcpcb.com/cyt Including single-sided aluminium boards just $2 for 5 pieces My wireless "bin lid monitor" module could be used in many ways: detecting post, monitoring a gate or garden shed door and even as a burglar alarm detector! Let's walk through the steps I took to get it this far whilst you think about what you could use it for. ► Timestamps 00:00 Welcome Back 04:55 Power Supply 14:22 Wireless Data Transmission (nRF24L01+) 19:18 The μController 25:18 Designing the PCB (incl.
