+# ESP Door detector
+
+## Hardware used
+- 2x ESP32-C3 Supermini
+- 1x Red LED
+- 1x White LED
+- 1x Generich Reed Sensor
+- Resistors:
+    - 2x about 75Ω, I used the closest I had which was a 220Ω in series with a 100Ω Resistor (using a singe 100Ω Resistor each might also work, tho at lower brightness)
+
+## Software used
+- VScode with PlatformIO
+
+## Install / Usage
+- You can change the used pins at the top of each `main.cpp`, the defaults are
+    - **Receiver**
+        - LED `4`
+    - **Transmitter/Sender**
+        - LED `0`
+        - Reed Sensor `4`
+- Upload door-detector-sender to the ESP that will be installed a Door
+- Upload door-detector-receiver to the ESP that will be your indicator (for example besides your monitor)
+- Test if everything works correctly **BEFORE** soldering the components, I reccomend to use a Oszylloscope to check if the receiving ESP pulses at about 3Hz (300ms) on pin 4
+- If everything works correctly, you can then start by twisting together one 220Ω and one 100Ω Resistor
+- Now Solder one end of the Resistor-packs to the shorter leg of each LED, then solder the other end to the Ground pin (G) on the ESP
+- Continue by soldering the other Leg of each LED to the specified Pin above
+- At this State you should be able to plug both ESPs in and see each one shortly blinking at boot. After a few seconds, the Receiver's LED should start to blink at 3Hz. If not, check if each ESPnd for any shorts on the boards
