Edit: The clock shield is not compatible with the Leonardo. The clock and relay shields need a set of stacking headers to fit together.
Edit again: The clock and relay shields are not compatible; the display control pins conflict with Relay 2 and 3.


I have discovered new circuit boards and have reconsidered my design for a self-bondage timer.

https://store.arduino.cc/arduino-uno-wifi-rev2

With these 2 boards, nearly anyone can build a self-bondage timer. Now, if only there was a display, some buttons, a RTC (real time clock), and a temperature sensor. Oh, wait.

A complete timer can be assembled with these parts without soldering. I bought 2 relay boards and some clock shields this morning and am looking forward to building a new alarm clock. Also going to make a bondage controller.

Anyone have any thoughts on this?

I once bought a set of 36 sensors for experimentation. There are also LCD screens. The Wifi shield is interesting to know, thank you Riddle.
Now electronics is within everyone's reach. You don't even have to solder for workarounds and you can get a variety of breadboards.

Neat links. The WiFi link goes to an Arduino controller with built-in WiFi, no shield required.

Received the relay shields and the clock shields yesterday. The clock shields came fully assembled. Using an Arduino Leonardo for the controller. The clock shield will not fit on top of the relay shield because of the ICSP female header on the bottom of the clock shield hits the screw terminals on top of the relay shield. Not sure what the white epoxy is doing on the bottom of the clock shield. The battery holder for the RTC is under the 7 segment display.

There is likely a "chip scale package" (bare silicon, sometimes called a "flip chip") chip under the epoxy, so best leave it alone. Bare silicon needs to be covered as even light can disturb it's function and cause it to fail. (a bright flashlight or the sun shining through the circuitboard might do it too, so be careful where you place that thing.)

If you buy some header strips (like those already on the board) of the correct pitch, you can stick those in between the 2 boards if you really want to stack the clock shield and the relay shield. Or remove the ICSP headers if you don't use those and have a soldering iron.

Found another issue. The SCL and SDA pins do not match between the clock shield and the Leonardo. The clock shield looks for SDA and SCL on pins A4 and A5. The Leonardo has SDA and SCL on 2 and 3. Guess this idea needs more work.

Another update: got proto shields for use as spacers and assembled it all together with an Arduino Uno compatible board. Still not working together .

The display control pins conflict with the relay control pins.

We'll get there. And don't be afraid to enlist the communities' help.

just a question why are you trying to stack them you can use wires and mount them separately then there is less fitment head aches

I wanted something that just plugged together and worked.
