Before DISCARDING your old MICROWAVE OVEN, remove the TIMER. In this TUTORIAL video on Projects with MOTORS and other ELECTRICAL machines, we will see what we can do with a recycled timer from an old microwave oven. For safety reasons it is better to connect the phase to the switch and the neutral to the coil since this way no current reaches the bulb when the timer is off it works in both ways but for safety it is better to connect it like this. Before starting with the video tutorial, remember that the microwave oven works with high voltage, which is very dangerous. A minimum of knowledge in both electricity and electronics is recommended. To assemble this circuit, the first thing is to disconnect from the electrical network, then discharge the capacitor or high voltage capacitor I leave you a card at the end of the video, after there we are going to remove the timer or TIMER, we are going to see the structure of the timer some simple technical data and I am going to explain the connections it has and what each pin is for, to put it to use. To operate we are going to use a lamp holder and a bulb can be LED or any other type, a recycled electrical cable from any other electronic device or appliance, recycled cable in this case it is cable and connectors recycled from an old washing machine, and we can also remove the box where the timer goes to know how many minutes we want to have the light on and after this time it turns off by itself, at the end of the video we are going to make it work and I am going to leave you an electrical or electronic diagram so that you can make the connection easily, remember that it is very dangerous to handle the 230v mains voltage so make sure before starting it that all the connections are well made. It is an electronics project that you can do yourself in the workshop and you can get a lot of benefit from it at practically zero cost if you like the video don't forget to leave your LIKE thanks.
