Hi, lol. It's not heavy at all. Our cupboards are stupidly low - only about 30cm from the worktop surface as fitted by the builders!! We have a normal kettle too - which lives on the worktop !!I suggested to the wife that I make something similar for the toaster - she declined the offer 😀
View Instructable »Lol. The kettle matches the tea and sugar caddies whereas the one cup doesn't!! (It's a woman thing I think).I too love alexa and IOT. My wife just tolerates me lol.My favourite IOT is Milk in my fridge (see my instructable). It uses Thingspeak for a visual indication of how much milk I have. I made a similar device which tells me how much sugar I have in the cupboard too !Keep up the good work 😀

Hi, many thanks. I really enjoyed making it.
View Instructable »Hi there, thank you. Re one motor, as I said in my preamble I did try this with just one motor. I tried using 3D printed gears and lever type arrangements but I struggled for room and definitely a lack of engineering experience which is why I opted for the easy option (for me that is) !The motor driving the slide is noisier than intended but its not struggling, I tested it with 2 x2Kg weights in all positions on the turntable which it worked fine with.(A full kettle weighs around 3Kg). The motor does not turn for long and doesn't get warm. It was less than a fiver so expectations weren't that high :-).

Disadvantage of using ESP8266-01 & this circuit - on initial power up, both GPIO0 & GPIO2 must be high for normal boot ! The circuit holds GPIO2 sufficiently low to prevent a normal boot :-(.Replacing the 56 ohm resitor with a 3mm LED solved this !!
I had problems with the opto coupler in the hardware pictures. I had success with opto couplers labelled EL 4N35 528. I have built 3 of the switches using this component with no problems.Terry
HiI have tested with an ESP8266-01 using the circuit attached. Only mods to the program sketch are as follows:-Interrupt is now GPIO0 (was 13)relay is now on GPIO2 (was GPIO4)so all references to these pins need changing in the code.DO NOT have GPIO connected when uploading the sketch as it will fail !I have replaced the opto coupler with a BC337 & a 56 ohm resistor. Any NPN transistor should suffice. I use a resistor to limit the current - it was the value I had available that worked. I'm sure there is a mathematical formula for calculating this value :-)
View Instructable »Hi, it is ENable. This pin must be pulled high otherwise nothing works - it's the equivalent of the CH_PD on the esp8266-01Terry
- samsungite commented on samsungite's instructable Alexa and Switch Operated Lamp
Hi, your assumption is correct- I have not tested this with the esp8266-01as long as you can set one of the GPIOs as an interrupt and the other as an output the code should work.Just a note Re the opto coupler - I purchased 5 x 4N35 from the UK and the internal transistor would not turn on hard enough to enable the relay :-(. I will check the manufacture of the opto's which work and post the info tomorrow.Terry

HiThe protues software looks interesting !!It has been a while since I programmed the PIC chips.The code has to be compiled using Microchip MPASM and then uploaded to the PIC !Programming PIC chips using assembly code can be challenging and at times, frustrating.I changed to Arduino mainly due to the amount of free knowledge and examples there are on the Internet!Programming, debugging and testing are so much easier using the Arduino - and they are so cheap too!I am not too sure what your goals are, what are you trying to achieve please? Is it for learning or a particular project?kind regardsTerry

HiI think the display is blank because there is NO data in the eeprom!I made the project again with HC-06 and it works fine :-)First of all, copy these 8 lines of code and paste them AFTER the lineBTSerial.flush();EEPROM.write(1023,4);EEPROM.write(400,7);EEPROM.write(405,'L');EEPROM.write(406,'o');EEPROM.write(407,'c');EEPROM.write(408,' ');EEPROM.write(409,'4');msgsize=5;Recompile & upload the program to your Arduino.When uploaded, the display should show 'Loc 4'Now delete the 8 lines of code or /* rem them out */ as you only need to run this once. Re compile and upload the code again.The display should still display Loc 4.If your Bluetooth is connected correctly, you should see some strange characters on your android phone display ! (see image).The display connections are :- 5v &…

HiI purchased an HC-06 ! I have tested it with arduino and android. I can send & receive messages both ways ! Therefore, my previous statement ,'the HC-06 is receive only' is totally incorrect!The sketch should run with either HC-05 or HC-06 !Apologies for the confusion. - Let me know how you get on :-)kind regardsTerry :-)
View Instructable »Re the ESP-8266 Door Alarm - That is brilliant !!!Many things can, and do go wrong, even to experienced people! It is great that you did not give up - well done !!There is great satisfaction when a project finally works :-) :-)I used the ESP-8266 in my 'Milk in Fridge' Instructable over a year ago & it is still working !! I can go to www.thingspeak.com and see how much milk I have when I am shopping !Re the Matrix display.If I understand you correctly, you would like to display your own messages on the display ! This is simple :-)Enter any message. When it is in the display, send the "~" character followed by a number 0 to 9, for example, Enter the message **INSTRUCTABLES** and see it on the display.If you now enter ~3 (for example) the message **INSTRUCTABLES** will be st…

Thank you. These timers are ideal for controlled switched mains sockets and so cheap too.
- samsungite commented on samsungite's instructable 8x8 Matrix Display with BTView Instructable »
Its a GREAT Name :-) :-)it looks like you are correct, HC-06 is receive only.In theory, this should still work with one exception - on power up the EEPROM contents are read and sent to the mobile phone, this will not happen, however, it should still update the display as the Arduino is receiving the information !You may have to comment out any line starting with BTSerial.println, but it should work !Good luck
