This project was started in April 2022 and the objective of this project was to restore an exterior electric gate that had not worked for over 15 years.

### Context
In my yard, there has always been an electric gate that I have seen work very few times, if ever.
## Context
In my backyard, there has always been an electric gate that I have rarely, if ever, seen work.
I decided to repair it as I felt I had the DIY and electronic skills to get it working again.
I decided to fix it because I thought I had the DIY and electronic skills to make it work again.
This courtyard gives access to different houses and the access to it is therefore shared. This implies that the operation of the latter must be low, easy and without constraint.
This gate gives access to different houses and therefore its access is shared. This implies that its operation should be low, easy and unencumbered.
### Choice of technologies
It has not worked for about fifteen years since it requires a 230V three-phase power supply. The subscription was cancelled to have only single-phase and the gate remained open since that day.
#### Hardware
## Before anything
For this project, I had the opportunity to make my own electronic board in order to build a reliable, clean and easy to install system.
The state of the portal before starting my project was as follows:
- A three-phase motor that needs to run on single-phase (conversion required).
- Mechanical limit switches to be changed
- A broken photoelectric sensor to be changed
- The electronics of the gate to be completely redone

## Required elements
### Hardware
For this project, I made an electronic board to build a reliable, clean and easy to install system: [LiHoCo Yard gate PCB v1.0](hardware/PCB/yard_gate_pcb_v1.0.md)
I also needed other components such as:
- [Mechanical limit switches](https://www.conrad.fr/fr/p/interrupteur-de-fin-de-course-tru-components-xz-9-108-1426610-250-v-ac-10-a-levier-pivotant-a-galet-a-rappel-ip65-1-pc-s-1569253.html)
- [Photoelectric sensor](https://fr.aliexpress.com/item/32810795246.html)
- [Warning light](https://fr.aliexpress.com/item/1005002878506861.html)
- [433MHz RF remote control](https://fr.aliexpress.com/item/1005003238379943.html)
- Junction box
- Cable
### Software
[ESPhome](https://esphome.io/) was the easiest solution to implement the portal system. I used it to make my ESP32 program
## Points of improvement
### Security : No rolling code
The EV1527 433MHz receiver module does not allow code rolling as the HCS301 KeeLoq protocols do. Nevertheless, since the gate does not give any access to the interior of a house, this point does not really pose a problem.
