Thou I have decades of programing, I have about 3 days of Electronics. Lol
I watched 20 hours of YouTube vid’s on the basics, but it is now time for me to make my first project.
I am starting simple. So I want to control a srd-05vdc-sl-c relay from an esp8266 gpio.
I don’t want to use a relay board, I want to build out the circuit, including the math. Woot…
So if I understand the problem correctly.
The gpio is 3.3 at 24ma and the relay requires 120ma to activate.
The first of many questions is how is driving this relay best accomplished without drawing to much current from the chip?
2) Optical coupler?
3) Reed switch?
What I wouldn’t do to have a day with a hardware guy…
Who is up to spoon feeding a noob
