Flyback Diodes are used with inductive loads like dc motors and relays. Lets use a relay for an example. A common relay has a 12v 120 ohm coil. In use it draws .1 Amps. When you turn off the power, energy is pumped back into the circuit briefly as the field in the coil collapses, …
Many of our projects are running off the common 18650 Lithium Ion battery, so today we wanted to talk about the math of charging, and of course we want to use an Arduino to manage that charge. Lithium Ion batteries need a Constant Current (CC) / Constant Voltage (CV) charge. It starts out in CC, …
I wanted to monitor temperature with a ESP8266, and display the results on a web page. I grabbed a DS18B20 temperature sensor, and created a web server to display the results. I decided to use Ajax, so that the results would autoupdate without having to reload the page. The question came up, what IP address …
Do you want to learn Computers, Electronics, and Programming? For the last 40+ years kids and adults alike have been building their own computers instead of buying prebuilt, preloaded systems. Times have changed, and so has hardware and software. Some of the coolest tech comes in kit form, so not a lot of building is …
