Week 9 - WEMOS Testing and updatez
WEMOS D1 Mini Pro
Unlike the ESP-01 like before, this WEMOS has no need for an FTDI power converter. Where the ESP01 requires different configuration for AT command mode/ serial monitor display/ downloading of program, the WEMOS is able to connect a COM PORT simply and have serial monitor display/ downloading of codes done without much hassle.
The displayed serial monitor is able to indicate the WEMOS being connected to the Local WiFi network as well as showing the IP address of the WEMOS to connect to the web server. The web server is created by the program and accessed by typing in the IP address of the WEMOS into any browser.
December 8th, we received a WEMOS D1 Mini pro module from Mr. Joe to play around. We were tasked to replicate the simple task of controlling the LED using a web server created when a program is run by the WEMOS. This is the same program done by STEM Education on their Internet of Things Blog.

The web server is the same web server as before, allowing the user to on and off the built-in LED wireless using only WiFi as shown in the video above. Once the WEMOS has the program inside it, the WEMOS can be connected to just a battery pack and still be controlled from the web-server at the IP address, similar to the ESP-01
Update on our past schedule
Week 8 - MST Week
MST was still on-going during the previous week, week 8, as such the fab lab wasn't open when we visited it. It was open on Wednesday 7th Dec when we went for our laser cutting training in the afternoon. (In hindsight, we should have went to the fab lab @T14)
We focused on the software of our current speedometer and dashboard display, resulting in not much progress for the hardware (actual mount for the dashboard). We also talked to our supervisors regarding upcoming projects as well as defining the project scope that we would be focusing on after testing many different components
Week 9 - Holiday Week 1
We went to the fab lab straight away on Monday to work on our mount. We planned on doing 2 mounts to experiment. One mount consist of an acrylic sheet that is attached to a large wooden base while the other would be made out of acrylic. We sawed off the wooden part of the base as well as bent an acrylic sheet for the second mount. The sawing of the wood didn't go so smoothly and the edges were uneven. The acrylic bending was okay but it came out to be a little bit tall.
We were thinking how to attach the tablet to both mounts while ensuring it's easily attached/detached. There was also the 3 variable resistor that would need to be integrated into the mount. We built various circuit mount for our components but unexpectedly, the T10 lab was closed from Thursday to Friday so we didn't get a chance to work on our mount.

Main Objectives - Upcoming Tasks:
- Ensure that the Sensor are working
- Current Sensor (Amploc)
- Temperature sensor (DHT22)
- Speed-sensing (In progress, possibly looking into PWM)
- Integrating the Sensor into one system + LoRa
- Combining the variable resistor
- Integrate the sensors to the display (Tablet using Andriod studio)
- Finish up work on the mount
- Ensure that the tablet is secured onto the mount
- Drill holes for the 3 variable resistors
Carry on with the Slides for upcoming First Assessment
Side Objectives:
- Experiment the Wifi capabilities of the WEMOS
- Using HC-05/HC-6 modules as backup
- Start up a frame for the report
