The objective of this post is to explain how to fade a LED with the ESP32, using the LED PWM functionalities. Introduction The objective of this post is to explain how to fade a LED with the ESP32, using the LED PWM functionalities of the microcontroller. I will be using DFRobot’s FireBeetle ESP32 board to […]

HC-SR04 ultrasonic sensor modules, also commonly called ping sensors, are practically a dime a dozen, with many Asia online retailers selling them in the $2 to $3 dollar range each. While possibly not intended for an end solution or product, these sensors offer a more affordable option for prototyping and application development compared to the

I’m working on a prototype product(Wifi motion sensor) that will be powered from a battery source, it has a mega328(arduino bootloader, with sleep mode on and wake on interrupt,and WDT in case it hangs up), a PIR motion sensor , and a CC3000 break out board. Power saving is done in software, but what type

If you are contemplating building your own machine, then you probably already know a good bit about how pinball machines work. It’s basically series of electro-mechanical events where a steel ball activates a switch, which in turn fires a solenoid that drives a mechanism, sending the ball off in some other direction where it most likely hits another switch, and so

To see how RFM12B wireless compares to other similar wireless options (e.g Xbee, XRF etc..) check out this well compiled comparison overview by Stuart Poulton: http://blog.homelabs.org.uk/wireless-connectivity/. Overview Made by Hope RF, re-branded by RFsolutions in the UK. Sometimes called ‘Alpha RF’ Low cost RF transceiver (from Rapid, Farnell, or RS in the UK) Up to 300m transmission Up
